TECHNICAL TERMS

In the next few days, I am going to explain some technical terms pertaining to your Heating, Ventilation, and Air Conditioning (HVAC)system:

There are many technical terms used in the description of Heat Pump systems; most of them are self-explanatory, but I will help to explain what they mean. We will do a few a day.

Heat Pump: A heat pump is a device for transferring energy in the form of useful heat from one place to another. It cannot store, make or destroy heat energy – it simply moves it. There are a number of techniques that exploit heat transfer; the commonest in use is the Refrigeration Cycle. A heat pump is capable of transforming a large quantity of low grade, low temperature heat. Some air source systems will operate in winter ambient conditions down to -15ºC. Heat pumps are available that can operate in a variety of media Air, Water, glycol, etc.

Heating Only Heat Pump: Ground Source heat pump systems are often optimised specially to deliver heating only. These units are often capable of delivering greater overall energy efficiencies than reversible units because the system is designed for a constant unvarying load above the freezing point of water at the evaporator section and can dispense with the Defrost Cycle.
