TAKING ADVANTAGE OF FREE COOLING DURING THE SPRING SEASON
During this time of year economizer season is in full swing, if the temperature requires cooling to be needed. What are economizers and how can you best utilize this component during the spring season?
Economizers can provide free cooling when the outdoor temperature is below 60-65 degrees. Keeping these systems fully functional with thorough preventive maintenance testing and completing repairs as required, can save large amounts on electric utility consumption.
This is accomplished by introducing cold, outdoor air by opening a damper and tempering as needed to the space. The electric used to run the fan is needed in any cooling mode but operating in economizer mode saves a tremendous amount by not operating the compressor, which is the biggest electric load in the cooling system.
Economizer operations also prevent wear and tear on the mechanical cooling compressor by not running them in short intervals in cooler weather than they were truly designed for.
Units that do not have economizers are highly recommended to have one installed, if possible. Economizers also provide ventilation by introducing fresh air changes into the space, making the indoor environment non-stagnant and breathable.
Reduce energy costs, enhance comfort controls and reduce equipment footprint
With only two existing thermostats for over 14 classrooms and offices, Loyola Academy was looking for a better way to control the temperature in each classroom and office. Being located in the basement, the new system also had to be able to dehumidify to maximize its' occupants comfort.
With limited space above the ceilings, Loyola Academy and First Point's engineers worked together to find a system that would meet both the space limitations and provide additional comfort controls to the teaching staff.
First Point Mechanical designed and installed the Mitsubishi VRF system that provides each classroom and office simultaneous heating and cooling . This project turned two thermostats into 14 individual controlled zones! This project also freed up mechanical room space and allowed the building to utilize this additional space for storage and classroom use.
