AIR SOURCE HEAT PUMP INSTALLATIONS: A START-TO-FINISH APPROACH

摘要

An air source heat pump (ASHP) is a renewable heating technology, which operates in a similar way to a fridge, but in reverse. ASHPs collect air from outside a property and feed it through a heat exchange system to provide reliable, efficient and cost-effective space heating and hot water. ASHPs use a fan on the front of an outside unit to draw air into the internal system. Here it meets an evaporator, which contains a refrigerant that turns into gas when the air hits it (even at sub-zero temperatures). A compressor then brings the gas up to a high enough temperature to be transferred, via a condenser, to the hot water storage system. This feeds into the property's heat emitters. Meanwhile, the refrigerant reverts to its original liquid form, ready for the process to begin again. Utilising renewable heat from the air outside means ASHPs are a highly efficient solution for homes and commercial buildings. NIBE's ASHPs also use inverter-driven compressors to regulate electrical input, thereby minimising mains power demand and boosting system efficiency further. They can even operate in reverse to provide cooling in warmer temperatures.
