Spot cooling is an effective solution for a wide range of cooling problems. Spot coolers can be set up quickly and can be used just about anywhere due to their compact size. Once they are installed, spot coolers do not have to be constantly monitored, making them easy to maintain. Here are the top 5 uses for spot coolers:

1) Server Rooms/Data Centers - Unfortunately we can’t always rely on our building's central HVAC system. With these types of rooms there is a lot of concentrated heat being generated. Spot coolers can help keep the equipment cool and alleviate any hot spots. Building HVAC systems often shut down after hours or on weekends but luckily spot coolers can run 24/7.

2) Commercial Office Space - It is proven that workers are more productive in a comfortable environment. If the HVAC goes out or is just not keeping up with the heat, a spot cooler is a perfect solution for keeping the employees cool and comfortable.

3) Healthcare Facilities - Keeping patients and labs cool is crucial and oftentimes required. Whether it is a hospital, laboratory, assisted living facility, etc., spot coolers can maximize patient comfort and usage of the space.

4) Restaurants - When working anywhere where there is a kitchen, it is bound to get really hot. And if the HVAC system fails, you're left with the possibility of customers walking out and uncomfortable employees. A spot cooler is compact and portable enough to place in the dining area and in the kitchen.

5) Educational Facilities - Spot coolers are great for schools of any size because schools have so many individual rooms. When there is a cooling problem, you can place multiple units in spaces that you need to keep cool. This will ensure the faculty and students are comfortable.

Since 1987, Portable Air has been meeting the cooling needs of businesses in Florida and Texas. We serve clients 24/7 in Orlando, Central Florida, Houston, Pearland, Southern Texas, and the Southeastern United States. Contact us today!

Event Cooling: Back to the Basics

When it comes to party planning, even the most beautiful and festive décor will not count for much if guests are sweltering or shivering. Using the right portable cooling or heating equipment is vitally important to the success of an event. Here are the basics of providing portable equipment rentals for climate control in tents and other party locales.

How Can I Keep My Party Tent Cool?

An air conditioned tent makes for comfortable guests at an outdoor wedding, party or other event. Party tent air conditioner systems can be installed inside or outside of the tent. Read on to learn about the options.

Large 12- and 25-ton mobile air conditioning units are popular for event cooling because of their high cooling capacity. These units will typically be located outdoors with the cold air ducted in. Sometimes, however, multiple spot coolers of 1- to 5-ton capacity can do the job, and these air-cooled units may be located indoors or out depending on noise and space constraints.

Some customers prefer to use two or three smaller units instead of a single larger machine to provide redundancy in the unlikely event that one of the units experiences component failure. Once you’ve determined what layout you’d like, it’s time to consider how much cooling power you’ll need. Read on to learn more about cooling recommendations based on tent size.

How Much Cooling Does My Tent Need?

Having sufficient airflow to the tent is crucial for a steady and comfortable climate. As a rule of thumb, plan on one ton of cooling for every 100 to 150 square feet of area within a tent. That can add up to a lot of tonnages, but it will be needed to compensate for the thin walls of the tent and the resulting high level of air infiltration.

Whether you opt for the low or high end of this range will depend on the calculated heat load, which must take into account factors, including:

Since comfort is a big part of success, it is wise to build a little extra cooling capacity into the game plan for your air conditioned tent.

If the event is to take place indoors, the formula changes to about one ton of cooling for every 400 to 600 square feet of space. Again, the heat load must be calculated as above to determine more precisely how much cooling is needed. An experienced portable air conditioner company can help you determine the best course of action.

Portable Cooling in Open Tents and Open Areas

Portable AC for tents is not the only option for keeping guests cool. Another popular rental option for outdoor event cooling in open areas or open-sided tents is misting fans.

The Power Breezer misting fans have a cooling range of 3000 square feet and can cool a space up to 27 degrees without getting guests wet. Misting fans are compact, quiet and easy to assemble, ideal for various applications, including commercial sites and sporting events.

Operating the Power Breezer misting fan is a breeze. The misting fan conveniently runs off a generator (under 900W) and has easy universal controls. The misting fan has a 100-gallon water tank capacity, providing 4 to 5 days of continuous use.

It’s important to note that evaporative coolers do not offer the level of performance and comfort control associated with air conditioning. However, they still provide a good way to cool on a budget.

How Does Portable Cooling in a Tent Work?

Now that we’ve covered some of the party tent air conditioner options let’s discuss how the equipment performs. As you bring conditioned outdoor air into the tent, you will want to direct the air up or down to avoid blowing directly on individuals.

Cold air will fall and form a layer of comfort here before it is drawn back into the return air duct to be re-cooled. With this approach, smaller units distributed throughout the perimeter of the tent will be advantageous. Keeping the event cooling equipment outside the tent is preferable if possible. The area should be as sealed as possible to prevent cooling loss.

An alternative method is to pressurize the tent with no return ducts, which is a very common method to deliver even cooling distribution throughout the tent. The best approach will hinge on the size of the tent, conditions outside, and other factors.

Power Sources for An Air Conditioned Tent

You also will need to consider the available power supply for your tent with AC. Will you be drawing electricity from an adjacent building or home, and if so, what type of power?

A generator is often needed to support adequate tent cooling. Determine the length of electrical cable required to hook up the portable unit(s) to the power supply. The greater the length, the bigger the size needed to maintain voltage and current draw.

Event tip: Don’t forget cable ramps to hide the cables and prevent trip hazards. Diffusers should also be considered for ease of installation.

To the untrained eye, a server room looks like a mass of humming machines that take up space. But to a company that relies on the data stored in servers, this room powers multiple operations, keeping the business on a forward-moving path.

If your business has a large server room, protecting it from damage must be a top priority. Jumps in temperature are a threat to the security and efficiency of your server room.

In fact, inadequate server room cooling can lead to a halt in operations. This was the case for Microsoft when a portion of the company’s servers suffered a heat spike that rendered two of its websites out of service for 16 hours and impacted cloud storage software.

Understanding your options for server room cooling systems and the backup plans available arms your company with a protective shield in the face of unexpected situations.

Read on to learn about the types of data center cooling systems and how to protect your server room.

When A/C won’t cut it for server room cooling

Think that cranking up the air conditioner is a server room cooling strategy you can rely on? You may want to reconsider that. An air conditioner is a permanent system that cools a server room. But as server usage increases or the size of the server room grows, this initial system will be insufficient.

The reality is that large server rooms require more than air conditioning to regulate machine temperature. Here’s why:

Air conditioners don’t always meet data center cooling requirements. Data centers need around the clock cooling. Most air conditioners are not meant to run 24/7. Running your A/C at all times puts a strain on the machine and runs up the electric bill. So when it comes to server room cooling, air conditioning is not an ideal solution.

Another way air conditioning falls short of data center cooling requirements is the limited capability to regulate factors outside of temperature. In other words, air conditioners can’t protect your equipment from potentially damaging humidity. When humidity levels rise, condensation can form on machines, and problems ensue. Air conditioners are not designed to decrease the amount of moisture in the air and address humidity in the way that true server room cooling systems can.

Lastly, changing seasons impacts A/C settings. Data center cooling requirements indicate that servers need an environment between 68 and 72 degrees to continue operating. In the winter months, the heater is switched on in place of the air conditioner. Even when an air conditioner is running in your server room, the rise in temperature elsewhere in the building has an impact.

As you can see, an air conditioner won’t suffice for cooling a large server room. Fortunately, there are server room cooling systems that meet the needs of the equipment. Let’s explore them below!

Data center cooling solutions

We’ve covered the ways that air conditioners alone fall short of data center cooling requirements. Now it’s time to talk about a solution that can fulfill your server room cooling needs—spot coolers.

An A/C is a permanent system that needs support in cooling a server room. A supplemental machine that aids in temperature control is the ideal support system. Spot coolers are portable cooling machines designed to supplement a cooling source and address multiple temperature control issues. They operate by taking in ambient air through the return, which passes over a closed-loop coil containing refrigerant, reducing the room temperature. The cold air is then pumped back out into the room through the supply.

Unlike air conditioners, spot coolers have capabilities that tackle humidity. As mentioned above, high humidity levels lead to condensation on machines. Water droplets on machines is a server room nightmare. Spot coolers suck excess moisture out of the air to keep humidity levels in check.

In addition to their dehumidification abilities, spot coolers are also energy efficient. They utilize less power than air conditioners while delivering powerful cooling results. Since energy-efficient technologies are better for the planet and your bottom line, spot coolers are a win-win in this department. See how much energy different spot coolers require in this handy chart.

With spot coolers, you don’t have to deal with complex machinery and high maintenance types of data cooling systems. The user-friendly aspect of spot coolers is what draws many businesses to them. Installation is typically done within a couple of hours, and selecting the desired temperature is a simple process.

Why you need a backup cooling system

The importance of server room cooling systems is evident. But having a reliable backup system like a portable cooler is just as pivotal.

One key reason to add a backup cooling system is to save equipment in the case of unforeseen disasters. When hurricanes cause mass electrical power outages, air conditioners fail and leave ill-prepared companies with server rooms with no other means of regulating temperature.

Another benefit of a backup cooling system is its ability to power up at a moment’s notice. If a cooling system fails, a portable cooling system can be brought in to keep the temperature regulated. Because spikes in temperature can damage servers in a short amount of time, having a backup can prevent a company from shelling out hefty sums due to damage.

From natural disasters to machine malfunctions, there are certain situations that even the most organized companies never see coming. In these cases, you can rent a portable data center cooling system while the problem is addressed. Knowing that your servers are well protected brings peace of mind.

Keep your technology intact with portable cooling

Your servers are an asset worth safeguarding. To ensure that your server room is well-equipped for emergencies, having a supplemental cooling system is critical.

With an array of cooling systems including chillers, DX package units and spot coolers, Portable Air has the solution for your server room.

As the United States continues reopening job sites during the COVID pandemic, increased implementations of safety measures for employees and staff have become a crucial concern. This is especially true during the summer months, when the heat is unrelenting and sometimes brutal. And when you venture inside, safe air quality is something that should be a top priority, as good ventilation and airflow are vital with worries surrounding COVID. Check out Portable Air’s tips below to increase safety measures and garner quality airflow!

Ventilation and airflow

Experts such as ASHRAE have mentioned that proper ventilation can dilute virus particles in the air and help slow the spread of COVID. Experiment with airflow at your site to determine a pattern that works best for all. Airflow is essential for the health and safety of employees, so try to direct clean air towards less clean air if you can, and use open windows to bring in fresh air from outside on occasion as well. However, try not to use outside air too much, as it can impede your HVACs function by making your cooling system work overtime in summer and drive up energy costs. When outside air isn’t an option, mechanical ventilation can work beautifully as well, controlling the amount of outside air that enters your space and using ducts and fans to direct the fresh air where its needed, and to exhaust air from other spaces such as kitchens or restrooms. 

Check on your filter

A high-quality air filter can make all the difference, especially when viral contaminants are a concern. Check your air filters thoroughly to see if they need replacing and make sure to do your research when upgrading, as filters vary when it comes to the amount of particles they can remove from the air. The MERV system is a good metric to go by when it comes to this. The MERV (minimum efficiency reporting value) shows how well your filter is working and filtering the air. Higher MERVs mean more particles removed; therefore the filter will be better able to reduce the spread of damaging contaminants. Your HVAC system was made with a specific amount of airflow designed to work with it, therefore the MERV should be carefully considered for the appropriate balance of efficiency and airflow your site needs. If you need to discuss with an HVAC expert, we got you there!

Safety measures for surfaces

Healthy environments need to be maintained in the air and on commonly used surfaces as well. Make sure to regularly disinfect and clean your site, and lay out plans regarding social distancing. Keep cleaning products readily on hand as well for spontaneous clean-ups where needed. While you’re transitioning back to normal, keep an eye on health official recommendations about which practices to incorporate into your site.
