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.
