Air supply warmth pumps switch warmth, both from the skin air right into a constructing (heating) or from the constructing into the skin air (cooling). Their effectiveness in heating decreases because the outside temperature drops. At a sure low temperature, the warmth pump’s capability to extract warmth from the skin air turns into inadequate to satisfy the constructing’s heating calls for, necessitating supplemental heat.
Relying solely on the warmth pump in extraordinarily chilly climates might result in occupant discomfort and doubtlessly pressure the system, shortening its lifespan. The inclusion of a backup heating factor ensures constant indoor temperatures are maintained, no matter exterior climate situations. This built-in method enhances the general reliability and person satisfaction related to warmth pump techniques.
