Abstract
A refrigerant hammer arrestor includes a housing having an internal compartment communicating with a refrigerant line, a piston received in the housing and dividing the internal compartment into a first chamber and a second chamber and a damping mechanism to dampen displacement of the piston within the housing. Various refrigerant loops are also described incorporating a refrigerant hammer arrestor.
Claims11
A refrigerant loop, comprising:
- a compressor;
- a condenser downstream from said compressor;
- a first expansion device downstream from said condenser;
- a first evaporator between said first expansion device and said compressor;
- a first shutoff valve between said condenser and said first evaporator;
- a first refrigerant hammer arrestor between said first shutoff valve and said condenser;
- a battery chiller, a battery chiller expansion device and a battery chiller shutoff valve between said condenser and said compressor and in parallel with said first evaporator, said first expansion device and said first shutoff valve;
- and
- a second refrigerant hammer arrestor between said battery chiller shutoff valve and said condenser.
