Problems solved by technology
[0002] At present, casing pipes or single pipes are usually used as evaporators in water refrigeration devices. In this way, in the process of making cold water, local water may freeze, resulting in difficulty or failure to discharge water.
In the prior art, the stop of the compressor is controlled by detecting the temperature of the cold water to prevent the cold water from freezing due to the low water temperature. Unstable, sometimes high and sometimes low, so the compressor may start and stop continuously, which will lead to a decrease in the cooling capacity of the compressor and damage to the compressor

The invention discloses a water refrigeration device and a control method for preventing cold water from freezing. The water refrigeration device includes a water pump and a water outlet pipe with a water outlet. The water pipe is refrigerated by a refrigeration cycle system, and the refrigeration cycle system includes a compressor and a condenser. , evaporator and liquid accumulator, the compressor has an exhaust port and a return air port, one end of the condenser is connected to the exhaust port, one end of the evaporator is connected to the return air port, and the other end of the condenser and the other end of the evaporator are connected A throttling element is connected in series, and a solenoid valve is provided between the other end of the evaporator and the exhaust port. According to the control method for preventing cold water from freezing in the water refrigeration device according to the embodiment of the present invention, by detecting the water pressure and water temperature of the water pipe and controlling the opening or closing of the solenoid valve, the cold water can be effectively prevented from freezing, and the opening or closing of the compressor can be accurately controlled. Shutdown to avoid unnecessary startup or shutdown of the compressor, so as to ensure the refrigeration effect of the compressor and prolong the service life of the compressor.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a water refrigeration device and a control method for preventing cold water from freezing. Background technique [0002] At present, casing tubes or single tubes are usually used as evaporators in water refrigeration devices. In this way, in the process of producing cold water, partial freezing of water may occur, resulting in difficulty or failure to discharge water. In the prior art, the stop of the compressor is controlled by detecting the temperature of the cold water to prevent the cold water from freezing due to the low water temperature. However, the frequency of the user’s use of cold water and the amount of cold water used each time are uncertain, resulting in very high temperature of the cold water. Unstable, sometimes high and sometimes low, so the compressor may start and stop continuously, which will lead to a decrease in the cooling capacity of the compressor ...
