The compressor is equipped with a low temperature antifreeze
electric heating belt, which is beneficial to the low temperature
start of the compressor;
Introduction
The ultra-low temperature air source heat pump is a device that
uses air as a low-grade heat source for heating or hot water
supply. Its characteristic is that the quasi-secondary compression
jet heat pumping heat pump system can ensure the normal heating of
the unit at -25 °C, which realizes the possibility of heating the
air source heat pump in cold regions.
Features
Comfortable
The air energy heat pump is regenerative type, and the heating
function is automatically started according to the temperature in
the water tank or the air conditioning load to ensure sufficient
supply of hot water and air conditioning load for 24 hours. When
heating the hot water, there is no need to satisfy multiple faucets
at the same time as the gas water heater. With the problem of using
hot water, there will be no problem that the capacity of the
electric water heater is small and many people need to wait for a
bath. Instant hot water, large water output, stable water
temperature, to meet all your expectations for hot water.
Safety
Because it is not directly heated by electric heating elements, it
is a safety hazard for electric water heaters. Compared with gas
water heaters, there is no safety hazard such as gas leakage or
carbon monoxide poisoning, so it has better safety performance.
Low carbon fashion
Today, energy conservation and emission reduction have become the
trend of the times. Saving energy and reducing carbon emissions are
the most fashionable lifestyles. The air energy heat pump adopts
the inverse Carnot principle to transfer the energy in the air to
the water. It is not directly heated by the electric heating
element, so its energy efficiency can reach 4 times that of the
electric water heater, that is, heating the same amount of hot
water, and the power consumption is equivalent. One quarter of the
electric water heater greatly saves electricity consumption. 70% of
China's electricity is generated by coal burning in thermal power
plants. Saving electricity means reducing carbon emissions.
