R410A A+++ ERP R32 DC inverter Swimming Pool Heat Pump Air to Water
Hot Water Heater Pump
Features of EVI air to water (air source)heat pumps:
It applies A low-temperature heat pump system enthalpy-increasing
auxiliary circuit control method, a low-temperature heat pump
system and its enthalpy-increasing auxiliary circuit structure
belong to the technical field of refrigeration air-conditioning and
low-temperature heat pumps. It solves the problem of high cost and
complicated control of the existing electronic expansion valve and
thermal expansion valve, and the use of a single capillary tube
method cannot solve the problem that the high exhaust gas under the
extreme working condition of high compression ratio may easily
cause an alarm. The enthalpy-increasing auxiliary circuit structure
in the low-temperature heat pump system includes an economizer.
The economizer main circuit inlet on the economizer and the
external water-side heat exchanger, and the economizer main circuit
outlet and the external air-side heat exchanger are separated from
each other. One-by-one sealed connection and so on through the main
line. The advantages of the low-temperature heat pump system's
enthalpy-increasing auxiliary circuit control method, the
low-temperature heat pump system and its enthalpy-increasing
auxiliary circuit structure are: it reduces the production cost due
to the use of electronic expansion valves and the logic control is
simpler, while reducing the high temperature caused by the use of a
single capillary tube. Probability of alarming when the exhaust gas
is too high under the extreme conditions of compression ratio
EVI air source heat pumps are designed for domestic/commercial hot
water and house heating in cold areas where lowest air temperature
is above -25℃.

The casing of the unit is made of stainless steel anti-rust and
anti-corrosion material, which is durable, double-layer aluminum
foil fins for efficient heat dissipation and rapid defrosting.
The main engine adopts air supplementation and enthalpy technology,
which can operate normally at -30°C and good heating effects in
winter.
Imported electrical components have a failure rate as low as 0.1%.
The unit uses a special compressor for ultra-low temperature heat
pumps with a service life of more than 15 years.
