1.5.2. How heat pumps work
The heat pump system is mainly composed of four major components:
compressor, condenser, throttling device and evaporator. Its working principle is to
use electric energy to drive the compressor to compress the low-temperature and
low-pressure gaseous refrigerant into high-temperature and high-pressure steam,
then condense and dissipate heat in the condenser (plate heat exchanger), and release
the heat to the heat transfer medium (water ), the heat source is provided to the user
through the heat transfer medium (water) for heating or domestic hot water; the
condensed medium-temperature and high-pressure refrigerant becomes a low-
temperature and low-pressure liquid after being throttled by the throttling device,
and then passes through the evaporator (fin Plate heat exchanger) absorbs heat into
the air environment and vaporizes to form a low-temperature and low-pressure gas,
which enters the compressor again to be compressed, thus forming a repeated cycle.
