Summary |
| |
DHF 4-way reversing
valve, the key part of the heat pump air conditioner, diverts the
direction of the refrigerant flow under the electromagnetism of the
pilot valve to supply either heating in winter or cooling in summer
to the conditioned place. The character of the design of the DHF series
is twice-opening, the diversion is controlled by the pilot valve,
ensuring the high reliability of operation.
