How Does HVAC Pre-cooling work?

By combining 2 scientific principles:
  • Enthalpy of Vaporization: When water evaporates, latent heat energy is used to break the bonds between water molecules, allowing them to transition from a liquid state to a gaseous state. As a result, the surrounding environment is cooled.
  • The principle of increased surface area: A larger surface area allows more molecules to escape into the air, facilitating a faster evaporation process.
The result:

By creating an ultra-fine mist of water droplets, measured in mere microns, almost all of the water is exposed to the air immediately. The resulting evaporation is so fast that a tremendous amount of heat is absorbed in the process. As that cooled air passes through your condenser coils, it removes heat more effectively than hot air.

Addressing The Scale Issue

An Obstacle That Can Be Overcome

A Common Question?

"What about the scale and minerals in the water? Won't they build up on the condenser coils? Won't it lead to corrosion, clogging, and shorten the life of the equipment?"

The Solution - Proper Filtration

To mitigate the risk, we employ advanced water treatment solutions. Our sediment filtration system removes impurities and most minerals that can cause scale buildup and corrosion, while the anti-scale function in our filtration prevents mineral deposits from sticking to your coils, even if they get through the filter. This safeguards your investment by minimizing maintenance needs and extending the lifespan of both the misting and A/C components.


Designing Your HVAC Precooling System

For Residential A/C:

  • Our DIY kits come with everything you need to install the system- filter, feed line, control box, lines, fittings, and nozzles.
  • No pump is needed, simply hook it up to your water source.
  • The control box ties directly into the 24VDC signal wire solenoid at the condenser, so it only mists when your unit is on.
  • Each nozzle effectively covers approximately a 1 foot radius from its center point. For smaller units, this usually means just one nozzle on each side of the condenser. For units that are 3 feet or taller, 2 nozzles may be needed on each side.
  • The pre-built kits come in multiple sizes, so you can choose the option that matches your needs.

For Commercial and Industrial Applications:

  • Water Source Requirements: Most of our misting pumps require a water pressure of 40PSI - 60PSI coming into the pump while it is running. Having too little pressure and flow could shorten the pump's life span, lead to unwanted vibrations, or even prohibit operation.
  • Power Source Requirements:  We have pumps available for 110VAC, 220VAC, and 460VAC power types. Knowing what type of power you have available will be important when choosing the right pump(s).
  • Determining Pump Location: Power and water supplies are normally present near HVAC equipment, so finding a central location for the pump is usually easy. Unlike many of our competitors, our pumps come standard with a rust-proof, weather-rated enclosure, so it is okay for the pump to be out in the elements, as long as it will not be flooded or submerged. The pump should also be able to sit level.
  • Water Quality and Filtration: Excellent filtration is a high priority in HVAC precooling. For systems between .15 - 2 GPM, the individual sediment and scale filters are both recommended. For larger systems, the industrial sediment and scale filter is required.
  • System Control Options: Relay controls that rely on a thermostat signal are a common configuration. Many customers also add our built-in thermostat to their pre-cooling pump so that it only activates when ambient temperatures are above a certain level. Our goal is full automation without waste.
  • Tubing: Flexible tubing is easy to work with and suitable for most small-to-medium commercial systems. A common layout is displayed in the pictures and videos at the top of this page. Magnetic attachments are available to prevent drilling or installing fasteners near sensitive areas. For larger industrial applications, flow rates, pressures, and heat characteristics may require the use of stainless steel tubing. 
  • Measuring for Your System: 1 foot spacing between nozzles, both horizontally and vertically, is recommended for each condenser coil face. For Example:
