Claims

[Scope of utility model registration request]

In an aircraft ground air conditioning system that has two independent refrigerant systems, a heater system, a blower system, and a control system, and supplies cold and warm air to various electronic equipment rooms and passenger cabins of the aircraft on the ground, the above-mentioned 2. Each evaporator in the refrigerant system of the system,
The first stage and the second stage are arranged in parallel to form a two-stage, one-housing structure, and the refrigerant is passed from the main refrigerant passage of one refrigerant system to the first stage of each evaporator through an expansion valve. The refrigerant is supplied from the main refrigerant passage of the other refrigerant system to the second stage of each evaporator via an expansion valve, and
An aircraft ground air conditioner, comprising control valves for controlling opening and closing of refrigerant supply passages to either one of the first stage and one of the second stage.
