The R32 EVI DC inverter heat pump is a high-efficiency, energy-saving heating and cooling device that integrates R32 refrigerant, EVI jet enhancement technology, and DC inverter technology.

R32 Refrigerant: R32 is a new environmentally friendly refrigerant with a low Global Warming Potential (GWP), no ozone depletion effect, high heat transfer efficiency, and good fluidity, which can improve the overall performance of heat pump systems.

EVI Jet Enthalpy Boost Technology: EVI, or Enhanced Vapor Injection, involves adding an injection port in the middle of the compressor to inject low-temperature, low-pressure refrigerant into the compression chamber, reducing the compression ratio and enhancing the system's heating capacity in low-temperature environments.

DC Inverter Technology: By changing the power frequency supplied to the compressor, its speed can automatically adjust according to the actual load demand, achieving precise temperature control, while providing higher energy efficiency during partial load operation.

Compression process: The DC inverter compressor draws in low-temperature, low-pressure refrigerant gas and compresses it for the first time to intermediate pressure. At this time, the EVI injection valve injects a small amount of liquid refrigerant into the compression chamber. The liquid refrigerant quickly vaporizes, mixes with the original gas, and is then compressed a second time to the condensation pressure.

Heat exchange process: The high-temperature, high-pressure refrigerant gas after compression releases heat in the condenser, achieving heating (or absorbs heat in the evaporator to achieve cooling), and then passes through a throttling device to reduce pressure and temperature before entering the next cycle.
