The specific embodiment
Embodiment 1:
It comprises indoor apparatus of air conditioner, air-conditioner outdoor unit the water temperature self adaptation water source air conditioner system of the utility model; Air-conditioner outdoor unit comprises frequency-changeable compressor 12, gas-liquid separator 11, subcooler 10, electric expansion valve 8 and 9, heat exchanger 13, cross valve 2; They are connected to form the loop in order, and air-conditioner outdoor unit also comprises pressure sensor, and pressure sensor comprises high pressure sensor 1 and low pressure sensor 3; High pressure sensor 1 and low pressure sensor 3 are connected to the exhaust side and the suction side of compressor; Air-conditioner outdoor unit is provided with controller, and above-mentioned parts all are connected with controller, carries out comprehensive regulation by controller; Tracheae temperature sensor 4, liquid pipe temperature sensor 9, aqueous temperature sensor are set on the heat exchanger; They also are connected with controller, and the aqueous temperature sensor comprises inflow temperature sensor 6 and leaving water temperature sensor 5, and the input module that can import aqueous solution freezing point value is set on the controller.
Its control flow is such,
A) set up evaporator refrigerant temperature and low pressure value PS1 (evaporating pressure) database one to one, and set the freezing point value=evaporating temperature+water of the aqueous solution and the heat transfer temperature difference of refrigerant;
B) pass through the freezing point value that input module is imported the aqueous solution;
C) controller is sought corresponding low pressure value PS1 according to the freezing point value of input from database;
