ABSTRACT:
In a multizone air conditioning system, a controlled leakage of refrigerant is provided from the high pressure side of the system to an inactive fan coil circuit to raise the pressure therein, such that when that circuit is later brought into an active state, the flow rate of refrigerant suddenly entering the circuit, and the resultant noise, is reduced. In one embodiment the controlled leakage is provided by an orifice formed between the high and low pressure sides of a valve, while in another it is provided by capillary tubes interconnected between active and inactive fan coil circuits.
