Description

variable energy air conditioner

Technical field

The invention belongs to an air conditioner, in particular to a variable energy air conditioner.

Background technique

The existing variable energy air conditioner realizes the variable energy control by changing the frequency of the motor through the frequency conversion compressor. The cost of the frequency conversion motor is high and the control circuit is complicated, which is not conducive to popularization and application.

Contents of the invention

The present invention provides a variable energy air conditioner aiming at the deficiencies of the prior art, which adopts a fixed frequency compressor and a solenoid valve to control the variable energy output of the air conditioner, so that the refrigerant of the indoor unit can be effectively distributed to achieve energy-saving effect, and the cost is low .

The purpose of the present invention is achieved through the following technical solutions: a variable energy air conditioner, including a compressor, a condenser, a liquid receiver, an evaporator, a four-way reversing valve, connecting pipelines and a control circuit, characterized in that the The compressor described above is a fixed-frequency scroll compressor. The upper scroll of the compressor is a floating type. The unloading valve on the top of the compressor is connected to a bypass pipe, and the other end of the bypass pipe is connected to the suction pipe of the compressor. A solenoid valve is connected in the pipe, and the solenoid valve is connected with the control circuit.

One outdoor unit can be configured with multiple indoor units.

1. The present invention adopts a fixed-frequency scroll compressor, and a bypass pipe is connected to the suction pipe of the compressor at the unloading valve interface on the top of the compressor, and the compressor is loaded by controlling the opening and closing of the electromagnetic valve connected in the bypass pipe. Or unloading, the purpose of variable energy output and energy saving can be achieved. Its structure is simple and its cost is low.

2. One outdoor unit can be equipped with multiple indoor units, which can effectively distribute the refrigerant of each indoor unit of the air conditioner with variable energy output, and save electricity.

Detailed ways

Referring to Fig. 1 , a one-to-two variable energy air conditioner includes a compressor 10, a condenser 2, a liquid receiver 1, an evaporator 12, a four-way reversing valve 3, connecting pipelines and a control circuit. The machine 10 is a fixed-frequency scroll compressor, the upper scroll 11 of the compressor is a floating type, the unloading valve interface 5 on the top of the compressor 10 is connected to a bypass pipe 6, and the other end of the bypass pipe is connected to the suction pipe 8 of the compressor. A solenoid valve 7 is connected to the bypass pipe 6, and an electronic expansion valve 13 is connected to the refrigerant delivery pipeline of the evaporator 12, and the solenoid valve 7 and the electronic expansion valve 13 are respectively connected to the control circuit.

When the solenoid valve 7 is opened, the upper scroll 11 of the compressor rises, and the compressor 10 unloads, which is no-load output; when the solenoid valve 7 is closed, the upper scroll 11 of the compressor descends, and the compressor 10 is loaded, which is full-load output. By controlling the loading and unloading time of the compressor 10 within a fixed cycle, the purpose of variable energy output and energy saving can be achieved.

In FIG. 1 , the direction indicated by the solid arrow is the flow direction of the refrigerant during cooling, and the direction indicated by the dotted arrow is the flow direction of the refrigerant during heating.
