The low temperature air source heat pump produced by PHNIX is
called Polaris, which can run at temperatures as low as **5℃. Why
can this series of heat pumps operate at such low temperatures?
First, the compressor used for Polaris is different from the
conventional heat pump’s compressor. The conventional compressor
has two boreholes, namely discharge outlet and suction inlet. But
the Polaris compressor has three boreholes. Besides the former two
boreholes, there is anther borehole, called injection borehole. And
because of this, Polaris compressor is called EVI compressor,
namely Enhanced Vapor Injection compressor.
Second,
the refrigerant liquefied in the condenser then flows through a
plate heat exchanger, also called economizer. The liquid
refrigerant from condenser divides into two ways. One goes directly
into the economizer called the main stream, the other flows through
an electronic expansion valve causing an abrupt reduction in
pressure and temperature and then flows into the same economizer,
called branch stream. The main stream and branch stream exchange
heat with each other. During the plate heat exchanger, the main
stream liquid refrigerant is cooled again, which decreases the
temperature of the refrigerant and the branch stream refrigerant
evaporates and flows into the injection borehole. That means
increasing the subcooling of the refrigerant. In the economizer,
then, the refrigerant passes through an expansion valve. In
conventional heat pump system, the liquid refrigerant from the
condenser flows directly into an expansion valve. Obviously, there
isn’t any temperature difference between the condenser outlet and
the expansion valve inlet theoretically. So, this is what’s
different from the Polaris heat pump system.
