Tech tips : Let’s learn about the role of an injection in AWHP

Injection not only helps warm faster, but it also saves energy. Let’s find out more about injection through a theoretical approach.

Injection increases the refrigerant flow rate and lowers the discharge temperature by additionally injecting refrigerant into the middle stage of compression of the compressor

Maximum frequency increases as the discharge temperature decreases.

The room heating efficiency improves as the range of frequency widens.

The user feels at ease when the end-user is able to reach the desired temperature through increased performance.

In case of some refrigerants, high-temperature discharge can reached without an injection, but water outlet temperature may decrease due to an insufficient flow rate.
