Electrical control means for use in a heat pump system having dual compressors wherein the operation of each compressor can be staged independently and automatically except for those periods when the outdoor heat exchanger is undergoing defrost wherein both compressors are placed in operation.JAMES J...
A thermal zone demand controlled dual cascade arranged heat pump system and system controller for building spaces, having first and second heat pumps and having an air circulation system for circulating air to and from said thermal zones and including a conditioned air chamber having first and secon...
Air source heat pump is not direct heating by the heating element, but with a small amount of electric driving the main unit's compressor to work, the low temperature air is compressed to high temperature air, through the pipeline circulation system to heat the water, ...
A local Carrier expert can help you choose a heat pump system with an impressive HSPF and SEER rating that might qualify for local utility rebates. What Does a Heat Pump Do? Wondering, what is a heat pump? You’re not alone – it’s a common question. An air source heat pump is a...
How does a hybrid heat pump work? A hybrid heat pump system, also called a dual energy system, integrates a heat pump (air source or ground source) with your traditional gas furnace or boiler heating system – and potentially even hydrogen boiler in the future. A hybrid heating system monit...
