Panasonic compressor + EVI technology is Enhanced Vapor Injection.
Inverter-type control of the 4Heat pump compressor makes it possible to achieve its optimum operation by adjusting the power of the device to fast changing heat demands. This ensures efficiency that is 20% higher than other heat pumps. This is particularly important during extremely cold nights with temperatures as low as -35 degrees and warm sunny days, when the temperature increases up to several degrees above zero. A solution to the key problem is to ensure an adequate process of evaporator defrosting. Reducing the process of freezing and optimizing the whole heating system is only possible owing to the special design of the 4Heat evaporator and adequate drainage of condensate.

The heat pump may also be used for active cooling in the summer. For this purpose, we have a special four-way valve built in in the device. In this case, it is enough to reverse the direction of pumping of the compressor and the expansion valve, owing to which the flow of the refrigerant is altered and thus the direction of heat flow. We achieve this through the scheme of a reversible heat pump, i.e. in the heating medium circuit. The compressor is connected through a special valve, which makes it possible to reverse the direction of its powering. The four-way valve allows to fit one of the two expansion valves into the circuit. In the heating mode, the pump has a slightly higher power and efficiency compared to the cooling mode.
EVI Panasonic compressor + EVI technology = Enhanced Vapor Injection – this makes it possible to direct a portion of the refrigerant to an additional element of the circuit – a second heat exchanger in the external unit – by means of an additional expansion valve. The medium is evaporated in it, which then enters the compressor prepared for work in the EVI technology for the optimization of the 4Heat pump at a lower outside temperature. For this purpose, stepless control of the performance of Panasonic inverter compressors, which use EVI, is implemented in addition to controlled rotational speed of brushless fans.
The casing is built from high-quality steel, which owing to special profiles withstands high loads without deformations.
