DX system with filtered suction line, low superheat, and oil provisions |
摘要 |
A heating/cooling system has improved operating efficiencies due to low superheat provisions and a specially configured compressor oil return. For certain systems, such as direct exchange geothermal heating/cooling applications having sub-surface heat exchanges extending at least 100 feet below the surface and using R-410A refrigerant, a specific compressor oil may be used to further improve efficiency. |
