WebMar 30, 2014 · Iv'e been working on a side project that I can't quite get to work. It's a Copeland semi-hermetic compressor running 404a. The problem is that the suction side keeps going into a vacuum, while my high side is running at 215 psig. After the system is shut off the system balances out to equal pressure on both the high and low side. WebApr 11, 2016 · 0. Every thermodynamics cycle needs to do negative work to the environment, which lower its total positive work. For example, in Carnot cycle, the most efficiency possible: 1/ Engine receives heat from hot reservoir, expands and do positive work to surround. 2/ Surround does work to engine, compresses it and heat is rejected to cold …
