System for eliminating ice block of supercooled water ice-making apparatus by using heat of condensation

Abstract

The invention discloses a system for eliminating ice block of a supercooled water ice-making apparatus by using heat of condensation. The system comprises a refrigeration system composed of a compressor, a four-way reversing valve, a heat exchanger, a throttling device and a first plate type heat exchanger, a secondary refrigerant system composed of a first circulating pump, the first plate type heat exchanger, a second plate type heat exchanger, a first stop valve, a secondary refrigerant water tank and a second stop valve and a supercooled water system composed of the second plate type heat exchanger, a supercooling relieving device, an ice storage tank, a first filter and a second circulating pump. According to the invention, since the refrigeration system is provided with the four-way reversing valve, functions of the plate type heat exchangers are switched to realize supply of heat; the secondary refrigerant system is provided with a pipeline specially used for elimination of ice block; heat of condensation is used as a heat source of the system, so energy consumption of the supercooled water ice-making apparatus can be effectively reduced; during elimination of ice block, it only needs to heat a small amount of a secondary refrigerant in the pipeline, so the total amount of the secondary refrigerant needed to be heated can be decreased, energy consumption of the system in elimination of ice block is reduced, and the speed of elimination of ice block and ice re-making can be accelerated.

Description

technical field [0001] The invention belongs to the field of supercooled water ice making, and more specifically relates to a device and method for deicing a supercooled water ice making system by utilizing the principle of a heat pump. Background technique [0002] my country's energy is increasingly scarce and there are obvious peaks and valleys in electricity consumption. Therefore, the use of supercooled water ice making technology in the field of cold storage has gradually received attention. The state of supercooled water is unstable, and it is easy to cause ice blockage due to disturbance or low temperature when flowing through the heat exchanger, resulting in intermittent operation of the system, and may damage the heat exchanger in severe cases. At present, when using the supercooled water method to make ice, there are mainly two methods for removing ice blockage: one is to heat the heat exchanger or the medium with an electric heater, and transfer the heat to the i...

AI Technical Summary

Problems solved by technology

However, using an electric heater as a heat source to remove ice blockages consumes a lot of high-grade energy, and there are certain safety hazards; using the condenser to heat the fluid to remove ice blockages, the system is more complicated, the investment is large, and it is not suitable for small systems.

Generally speaking, the deicing and blocking methods used in the existing supercooled water ice making method are relatively scarce and have many shortcomings. The popularization and application of cold water ice making method is of great significance
