What is the expansion valve in HVAC & How it
works ????????????
Answer Posted / pjagan89
Expansion valve is nothing but the Throttling valve.
Refrigerant in the condenser is at high pressure and is in
the liquid state. So, Throttling valves are used to reduce
the high pressure fluid before entering into the evaporator
in order to cool the environment.
Answer: High pressure fluid from the condenser has to be
reduced before entering into the evaporator so that flash
evaporation can take place at a desired temperature.
