Hotel DHW 10.8Kw Inverter Pool Heat Pumps 380V With Low Temperature

Features of EVI air to water (air source)heat pumps: 

With patented low-temperature heat pump system, wherein the scroll compressor includes at least one injection interface, which is connected to heat exchanger A, heat exchanger B, heat exchanger C, accumulator, gas-liquid separator, throttling mechanism and cut-off The mechanism keeps the flow path in communication to form a low temperature heat pump system with a supplemental gas injection system; it also includes: an injection pipeline system, a pipeline from the inlet and/or outlet of the heat exchanger C is connected to the original low temperature heat pump through the throttling mechanism The supplemental gas injection system in the system is formed on the pipeline, and the injection pipeline system and the original supplemental gas injection system are jointly connected to the injection interface of the scroll compressor through the pipeline. The system includes a supplemental gas injection system and another injection pipeline system, which can ensure the safe and reliable operation of the low-temperature heat pump system at a lower ambient temperature, and expand the operating range of the low-temperature heat pump system. In addition, because of its simple structure, easy production, and low cost, it is suitable for wide promotion in low-temperature heat pump systems.

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.

The low-temperature heat pump system includes: a compressor, a first solenoid valve, a first heat exchanger, a combination valve, an outdoor heat exchanger, a second heat exchanger, a second solenoid valve, and a coolant circuit; the low-temperature heat pump system is in the first In one mode, the compressor, the first solenoid valve, the first heat exchanger, the combination valve, the outdoor heat exchanger, the second heat exchanger, and the second solenoid valve Connected sequentially to form a first circuit; wherein, the second heat exchanger is also connected to the cooling liquid circuit for heat exchange with the cooling liquid circuit. It can be seen from the above technical solutions that the present invention adds a heat exchanger that absorbs heat from the coolant circuit in the low-temperature heat pump system, which can absorb heat from the heat flow in the coolant circuit, thereby improving the stability of the compressor in the low-temperature heat pump system.
