Problems solved by technology

The important defect of this method of dynamically making liquid ice with supercooled water is that the supercooled water is easy to freeze in the pipe and cause ice blockage, which will greatly reduce the stability of the system and even fail to operate.

Embodiment Construction

[0021] Attached below figure 1 The technical scheme of the present invention is further described:

[0022] The compressor 5 and the condenser 4 of the present invention provide refrigerant to the ice making plate 2. The flow of the refrigerant is controlled by the electronic expansion valve 3; the refrigerant passes through the ice making plate 2, and the water in the water tank 1 passes through the outer layer of the ice making plate 2. ; The refrigerant evaporates in the ice-making plate 2 to absorb heat and freezes the outer water; at this time, close the electronic expansion valve 3, cut off the refrigerant passage of the ice-making plate, and continue to supply water to the outer layer of the ice-making plate; Without the supply of cold energy and absorbing the heat of the water, the ice layer on the ice making board cannot stay on the ice making board. Under the action of gravity, it falls into the ice storage tank 6 together with the water and collides with it. After crus...

Abstract

The invention relates to a method for preparing gravity fluid state ice and a device for preparing the same. The device comprise a water tank, ice making sheets, an electronic expansion valve, a condenser, a compressor and an ice storage tank, wherein a refrigerant outlet of the compressor is connected with a refrigerant inlet of the condenser; a refrigerant outlet of the condenser is connected with a refrigerant inlet of the electronic expansion valve; a refrigerant outlet of the electronic expansion valve is connected with refrigerant inlets of the ice making sheets; refrigerant outlets of the ice making sheets is connected with a refrigerant inlet of the compressor; water flows out from a water outlet of the water tank, and sprays to the outer surface of the ice making sheets; and ice outlets of the ice making sheets are correspondingly provided with an ice storage tank. The method and the device realize good preparation effect, does not occur the ice block phenomenon, and achieves the aim of better energy saving.

Description

Technical field [0001] The invention relates to a method and a device for preparing gravity-type fluid ice. Background technique [0002] With the emergence of energy shortages, the energy consumption of air-conditioning systems caused by the widespread use of refrigeration and air-conditioning equipment has aroused widespread concern in the current society. Energy conservation has become an urgent requirement under the new situation in the refrigeration field. my country has also proposed sustainable development. Country-building strategy. Ice storage is of great significance as an energy-saving design idea, and fluid ice has become the first choice for ice storage due to its good thermal characteristics. [0003] Compared with the traditional static ice making method in the existing ice storage air conditioner, the dynamic ice making method with supercooled water is adopted, because the heat transfer resistance between the refrigerant and the water is smaller, and it will not i...
