Web19 de jul. de 2010 · Trane CVHE420. I have been looking though all my books and manuals for the refrigerant charge on a Trane CVHE420. On the nameplate it is listed at 308kg, so we charged this amount into the machine. Started it up, and got only 45-50% full load amps, with the vanes at 100%. Massive discharge superheat of 40+ degrees C and high … WebDischarge temperatures can be 180-225 degrees before triggering a safety (assuming it has one) temps above 225 will breakdown the oil and cause damage. That said any temp above 130-140 will result in burns if you are in contact long enough. As others have said here take measurements of the system to troubleshoot.
Heat Pump Efficiency Improvement by Discharge Superheated …
WebHigh discharge pressure can be described as, the pressure of the compressor in the refrigeration system is produced by the discharge gases is usually more than the normal pressure generated in the outside of the compressor. Causes of the high discharge pressure: 1. When the compressor of the air conditioning system carry the cooling medium. Web3 de jul. de 2013 · This research presents how to improve the heat pump efficiency by using Discharge Superheat Control (DSH). Normal heat pump uses Suction Superheat Control (SSH) about 5 K. At this condition, it is an optimum condition for cooling COP but it is not the highest cooling capacity. To improve Heat Pump efficiency, it needs to get … shuffle blues backing track
