Planning for The Temporary Cooling Systems at Your Next Event 

If you're hosting an outdoor event held in tents or similar structures, it's vital to consider how to keep those temporary structures cool for your guests.  Unless your event will be held in the winter, you'll be facing two separate issues when it comes to cooling - the hot weather itself, as well as the combined body heat of many guests packed into a relatively small space.

This isn't an issue you can overlook or cut corners on, either.  Every year, there are dozens of instances where event planners failed to properly consider their air conditioning solutions, leading to heat exhaustion - or even heat stroke - among their guests. It's always a possibility when too many people are in a space that's too hot for comfort, if the proper cooling calculations have not been completed and the proper system put in place.

No matter the size of your event, the solution is to rent one or more temporary cooling systems.  These portable, stand-alone units can be brought on site to provide the air conditioning you need, then removed after the job is done.  There are options to fit any size venue and event budget, and it's something you must consider carefully in your pre-event planning.

Your Ultimate Guide to Temporary Cooling Systems for Events

1 - Choosing a rental service

Unless you are in the business of hosting events specifically, there's no reason to buy a temporary cooling unit.  They're extremely expensive to purchase and maintain, so the ROI just isn't there in most cases.  It is far more cost-effective to rent one for a day or two - plus, you get the benefit of the rental agency's expertise in choosing and deploying your cooling unit.

You want experts who have many years' experience dealing with heating and cooling solutions - preferably contractors who have dealt with many different scenarios.  Those will be the ones best suited to evaluate your situation and help ensure you've chosen the right unit for your event.  In some cases, they may even be able to remain on-hand, just in case something unexpected comes up.

2 - Understanding how event size relates to cooler size

The major question that people ask when looking into temporary cooling systems is "How big of a temporary air conditioner do I need?"  In this case, "big" is defined in terms of tonnage - but that's not the weight of the unit.   It's actually left over from the pre-electric days when physical ice was used for refrigeration.  One ton of ice has to absorb a certain amount of heat (288,000 BTU) to melt over the course of a single day.  So, simply put, a one-ton air conditioner provides an equivalent amount of cooling as one ton of melting ice.

When it comes to planning for the cooling of a tent, heat loads need to be taken into account. Black and white materials have different cooling requirements. Another consideration is the events taking place in the tent. For one person sitting in the event, you’ll need 500BTUs, while for one person dancing in a tent, you’ll require 750 BTUs of cooling in the tent. Now, imagine a tent at a festival in which 200 people are dancing. This requires large amounts of power and a significant commitment to cooling safety. Factors such as lighting and food prep can also impact the heat load in a tent.

3 - What if you have limited power requirements?

OK, it's all well and good to say you need a 10-ton air conditioner... but what if you're at a remote location without power?  Well, one option is to rent a generator sufficient to power the A/C.

However, there are also cheaper options in temporary cooling systems. We can offer BAF for the budget conscious. These systems offer basic air movement to simulate a cooling effect in the tent. Evaporative units are a popular choice when you need to minimize power use.  These require a constant infusion of water or ice and will have fans blowing, but they are very energy-efficient since most of their cooling power comes from the water\ice. However, this is only an option in low humidity environments.

The other option here is spot coolers, which come in a range from 10T to 50T and are suitable for most event applications. Like spot heaters, these are small self-contained portable air-conditioners, capable of pumping out around one ton of air conditioning to the nearby area.  Because they're small, they also have lower energy requirements - however, you will have to put them within the venue itself, rather than being able to duct cool air in from the inside.  Also, fans will be necessary to spread the air conditioning around.

Those with larger cooling requirements may use additional units alongside implementation of a chiller/air handler combination. This style of cooling, in which a lot of distribution ducting is required, is used for applications 50T and larger.
