Abstract
The utility model relates to a liquid impact prevention device for a compressor, in particular to an electric liquid impact prevention device for an air-cooling heat pump air conditioner, comprising a gas-liquid separator, a first liquid level sensor, a second liquid level sensor, an output pipe, an input pipe, a controller, a solenoid valve, a compressor exhaust pipe and a compressor. The compressor is connected with a condenser, a throttle valve, an evaporator and the gas-liquid separator in a closed-loop manner; the solenoid valve is mounted on the input pipe; and the first liquid level sensor and the second liquid level sensor are mounted in the gas-liquid separator. The electric liquid strike prevention device has the advantages of preventing the situation that a liquid refrigerant is sucked into the compressor to cause liquid impact due to the overhigh liquid level of the gas-liquid separator; reducing the size of the gas-liquid separator, saving manufacturing materials and space; and being simple in mounting and easy to realize production operation.
Description
Technical field
The utility model relates to the anti-liquid hammer device of compressor, the electronic anti-liquid hammer device of especially a kind of air-cooled heat pump air-conditioning.
Background technology
Existing air-cooled heat pump air-conditioning system heats in the work in the winter time, because outdoor environment temperature is low, the heating capacity decay is very big, has often satisfied not the requirement of air-conditioning thermic load, and indoor air temperature in air conditioned building reduces, degree of comfort decreased.At this moment; The air-cooled heat pump air-conditioning system can increase the pressure of refrigeration system condenser, reduces the pressure of evaporimeter, makes whole refrigeration system many when needing cold-producing medium than refrigeration when heating; When working conditions change; Having does not have the evaporated liquid cold-producing medium to get back to compressor and be compressed, because the incompressible characteristic of liquid, with " liquid hammer " fault that causes compressor.In order to prevent " liquid hammer ", present air-cooled heat pump air-conditioning system, at the bigger gas-liquid separator of compressor air suction mouth installation volume, this improper increase cost, and take up space.
Summary of the invention
The purpose of the utility model is to overcome defective of the prior art; Adopt the electronic anti-liquid hammer device of a kind of air-cooled heat pump air-conditioning, magnetic valve turned down when liquid was too much in gas-liquid separator, prevented that liquid refrigerant is inhaled into compressor and causes liquid hammer; Easy operating is installed simply.
For realizing above-mentioned purpose; The technical scheme of the utility model is to adopt the electronic anti-liquid hammer device of a kind of air-cooled heat pump air-conditioning, comprises gas-liquid separator, first liquid level sensor, second liquid level sensor, efferent duct, input pipe, controller, magnetic valve, compressor exhaust pipe, compressor.Described compressor is connected with condenser, choke valve, evaporimeter, gas-liquid separator closed loop successively, and described magnetic valve is installed on the input pipe, and described first liquid level sensor and second liquid level sensor are installed in gas-liquid separator inside.
The output circuit of said controller is connected on the coil of magnetic valve, the input circuit of said first liquid level sensor and the second liquid level sensor access controller.
The basic principle of the utility model: after using the utility model, when the liquid refrigerant that flows to gas-liquid separator is many, refrigerant level raises; When refrigerant level was elevated to second liquid level sensor, magnetic valve signal, closed electromagnetic valve were closed in controller output; Gas-liquid separator does not have the liquid refrigerant of input; The liquid level of gas-liquid separator descends, and does not allow compressor from efferent duct inhalant liquid cryogen, effectively prevents compressor liquid hammer fault.
The beneficial effect of the utility model is:
(1) when liquid is too much in the gas-liquid separator, closed electromagnetic valve prevents that liquid level is too high in the gas-liquid separator, and liquid refrigerant is inhaled into compressor and causes liquid hammer.
(2) reduce the size of gas-liquid separator, save the material of making, save the space.
(3) install simply, be easy to production operation.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Fig. 2 is the use sketch map of the utility model.
Among the figure: 1, gas-liquid separator 2, first liquid level sensor 3, second liquid level sensor 4, efferent duct 5, input pipe 6, controller 7, magnetic valve 8, compressor exhaust pipe 9, compressor.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2 the utility model specific embodiment is further described:
The technical scheme that provides according to the utility model; The electronic anti-liquid hammer device of a kind of air-cooled heat pump air-conditioning comprises gas-liquid separator 1, first liquid level sensor 2, second liquid level sensor 3, efferent duct 4, input pipe 5, controller 6, magnetic valve 7, compressor exhaust pipe 8, compressor 9.Described compressor 9 is connected with condenser, choke valve, evaporimeter, gas-liquid separator 1 closed loop successively, and described magnetic valve 7 is installed on the input pipe 5, and described first liquid level sensor 2 and second liquid level sensor 3 are installed in gas-liquid separator 1 inside.
The output circuit of described controller 6 is connected on the coil of magnetic valve 7, the input circuit of said first liquid level sensor 2 and second liquid level sensor, 3 access controllers 6.
The course of work of the utility model is: in the refrigeration system of air-cooled heat pump air-conditioning, compressor 9 is connected with condenser, choke valve, evaporimeter, gas-liquid separator 1 closed loop successively, behind use the utility model; When the liquid refrigerant that flows to gas-liquid separator 1 is many, refrigerant level raises, when refrigerant level is elevated to second liquid level sensor 3; Magnetic valve 7 signals are closed in controller 6 outputs, and magnetic valve 7 cuts out, and gas-liquid separator 1 does not have the liquid refrigerant of input; Compressor 9 constantly from gas-liquid separator 1 sucking-off refrigerant gas side by side to condenser; The liquid level of gas-liquid separator 1 is descended, prevent that compressor 9 from from efferent duct inhalant liquid cryogen, effectively preventing the liquid hammer fault of compressor 9; When liquid level drops to the position of first liquid level sensor 2; Magnetic valve 7 signals are opened in controller 6 outputs, and magnetic valve 7 is opened, air-cooled heat pump air-conditioning system operate as normal.The advantage of present embodiment is, when liquid was too much in the gas-liquid separator 1, magnetic valve 7 cut out, and prevented that liquid level is too high in the gas-liquid separator 1, and liquid refrigerant is inhaled into compressor 9 and causes liquid hammer; Reduce the size of gas-liquid separator 1, save the material of making, save the space; Install simply, be easy to production operation.
