| 摘要 |
The present disclosure provides a method of operation of a refrigerant system, which comprises a main refrigerant circuit, a reheat circuit, and a flow control device, which has a first position isolating said reheat circuit from said main refrigerant circuit, and a second position placing said reheat circuit in fluid communication with said main refrigerant circuit. The refrigerant system further comprises a controller in electrical communication with said flow control device. The controller is configured to move the flow control device to the first position during a cooling mode, and to move the flow control device to the second position during a reheating mode or an oil recovery mode. The refrigerant system controller can execute an oil recovery mode in continuous or intermittent manner.
