摘要： A multi-connected air conditioner unit and method of operating the same, wherein, when an air-side heat exchanger is put into operation, and a water-side heat exchanger is not put into operation, a four-way valve is used to control a refrigerant to pass through said air-side heat exchanger, in realizing the refrigerating or heating operation of said unit; when said air-side heat exchanger is not put into operation, and said water-side heat exchanger is put into operation, said four-way valve is used to control said refrigerant to pass through said water-side heat exchanger to heat water, in achieving full recovery of heat; when both said compressors are put into operations concurrently, a dispenser is used to transport refrigerant oil separated by a second oil separator to an oil inlet pipe, then it is input to said compressor via an air suction pipe; and when a portion of compressor is put into operation, and another portion of compressor is not put into operation, since said air suction pipe is installed upright, said refrigerant oil getting into said compressor not in operation will return to said dispenser under action of gravitational force, then it will move into said compressor in operation, hereby ensuring safety of compressor operations.

摘要： A screw type wind-chilling water chiller unit including a chassis and a compressor, a shell and tube heat exchanger, a fin-type heat exchanger and an expansion valve, and a control cubicle disposed on the chassis. The expansion valve is disposed between the compressor and the shell and tube heat exchanger. The shell and tube heat exchanger is provided with three tubes, a first tube connected to the compressor, a second tube is connected to a liquid storage can via the expansion valve and a transmission tube. A heat exchange tube in the fin-type heat exchanger is connected to a collection tube, and the liquid storage can is connected to the third tube, and a handle of a cubicle door of a control cubicle is connected to a power switch inside a power supply box, so as to improve the performance, operation stability, equipment safety of the unit.
