A kind of air-conditioner closed-cycle system, comprise evaporator, flow controller, hydraulic ejector, water pump, high-pressure hydraulic pump, condenser holding vessel, globe valve, cooling tower, heat exchanger and blower fan, the evaporator top is connected in the hydraulic ejector sidewall by pipeline, and water pump is connected with the hydraulic ejector top by pipeline; The evaporator bottom is connected with the holding vessel bottom of condenser holding vessel by flow controller; Condenser one end in the condenser holding vessel is taken the bottom by high-pressure hydraulic pump, globe valve with cooling water and is connected, and the condenser other end in the condenser holding vessel is connected with the cooling tower top by pipeline; Evaporator inside is connected with tubulation in the heat exchanger by feed tube and liquid back pipe, and the blower fan discharge pipe is connected with the heat exchanger blast pipe, and the heat converter air-out pipe is connected to each air port, room by flange.
The installation connection description of air-conditioner closed-cycle system operation principle of the present invention, working medium, cooling-water flow process and equipment is as follows:
Evaporator is at least one, can be many, bottom in evaporator is marked with the working medium of liquid hydrocarbon, be transported to by feed tube in the tubulation of heat exchanger, outside the tubulation of outdoor normal temperature air in blower fan is sent to heat exchanger, make in the heat exchanger atomizing of being heated of the above-mentioned working medium in the tubulation by the outer fin of tubulation, the working medium after the atomizing enters into the top of evaporator by liquid back pipe, and then the working medium of evaporator internal upper part is gas-liquid phase working medium.
The evaporator top is connected in the sidewall of hydraulic ejector middle part by pipeline, on the condenser holding vessel, be provided with a water pump at least, can be many water pumps, liquid refrigerant in the condenser holding vessel pressurized back in water pump is transported at least one the top that also can be many hydraulic ejector that matches by pipeline, liquid refrigerant is flowed out downwards by trunnion by the hydraulic ejector top form throttling, then in hydraulic ejector, form negative pressure, its negative pressure value is about 0.097Mpa, simultaneously, make evaporator 1 top also form negative pressure, then the gas-liquid phase working medium of evaporator internal upper part enters into the condenser holding vessel through hydraulic ejector.
In the condenser holding vessel, pipe bundle condenser is arranged, mobile cooling water is arranged in the pipe bundle condenser, cooling water after condenser one end will be heated is contained in the pipeline globe valve by high-pressure hydraulic pump through string and delivers to the cooling tower bottom, cooling water in the cooling tower enters the other end of condenser under the gravity effect, then cooling water is circulating between condenser and cooling tower under the high-pressure hydraulic pump effect; Cooling water in the cooling tower carries out air-cooled through electric fan, make the temperature difference of Inlet and outlet water in the cooling tower reach 8～12 ℃, and globe valve is just used for the flow of regulating the above-mentioned recirculated cooling water of control.
In order to replenish the hydrocarbon working medium in the evaporator, at flow controller one end that the bottom of evaporator connects by pipeline, the flow controller other end is connected to condenser holding vessel inner bottom part, makes liquid refrigerant in the condenser flow into the bottom of evaporator.
Air-conditioner closed-cycle system advantage of the present invention is that equipment cost is cheap, and power consumption is little, and is energy-conservation, and the working medium of employing is the environmental protection hydrocarbon.
Description of drawings:
