Abstract

The invention discloses a capacity measuring device for a four-way reversing valve. The capacity measuring device comprises an air-conditioning refrigerating and heating system simulation part, an air-conditioning nominal condition adjusting part and an air-conditioning system parameter measurement part. According to the capacity measuring device, the air-conditioning refrigerating and heating system simulation part is used for simulating system compositions, in an actual air-conditioning system, of the four-way reversing valve, the air-conditioning nominal condition adjusting part is used for adjusting all component parts of the refrigerating and heating system simulation part to an air-conditioning nominal condition, and the air-conditioning system parameter measurement part is used for measuring all temperature and pressure parameters needed by calculating a capacity value of the measured four-way reversing valve. Accordingly, the capacity measuring device provides a testing platform conforming to standard requirements for measuring the capacity of the four-way reversing valve.

Description
