Monoblock-type 4Heat pumps use the same technology as split-type pumps built around Panasonic compressor + EVI.
Advantages of EVI – Enhanced Vapor Injection:
A smaller compressor is needed to achieve the same heating efficiency, i.e. lower costs, weight, vibrations, and noise.
Constant performance at changing temperature of evaporation and constant parameters of compression.
Very wide so-called work envelope – shown on the graph.
Steam postinjection protects the compressor itself against excessive pressure and temperature
Cooling efficiency higher by 25%; performance higher by 20 %, especially at higher pressure ratios.
Possible control of performance by means of steam injection.
Smaller diameter of liquid circulation to the main evaporator.
Smaller amount of R32 medium in the circuit.
In the Monoblock version, you do not need the F-GAZ allowance. Theoretically, this makes it possible to install the heat pump yourself. Of course, knowledge and experience are welcome 😊 Monoblock is not equipped with an internal unit – warm water or, ideally, glycol is pumped inside the building to the hydraulic part. In the case of a power failure, the best solution is using glycol, which will not freeze and burst the device.
