A traditional system

My neighbor works at one branch of a popular chain of stores in our city. Spring seems to be coming in earlier this year so everybody is out shopping for springtime goodies. Things ranging from lighter, cooler clothing, to seeds for the garden to invigorate the soil. The problem at this store though is with the temperature. After the freezing cold winter season had passed, the heating system in the store was still pouring out warm air! To the discomfort of everyone there, the store was far too hot. Instead of the gas furnace and AC seen with the traditional HVAC system, the air quality in this store is regulated by a geothermal heat pump. These particular heat pumps are used mainly in moderate climates, and are much more energy-efficient than central air units. The heat pump functions much like a refrigerator, shifting warm air to cool spaces and vise versa. This is the air-source heat pump and it’s even better with dehumidifying the air than the typical HVAC unit. So instead of generating heat in addition to cold, heat pumps move the air from inside to outside or the reverse, to achieve the desired temperature. In the case of our friend’s store, there was some confusion with the thermostat, and it felt like the desired cool air was being cancelled out by warm air coming from the heat pump. From what I hear, this is a minor problem which may be corrected. I sincerely hope so! I’ve always favored Summer over Winter, but this heat can be downright atrocious.
