Abstract

PURPOSE:To provide an ice making plant which is capable of manufacturing ice in particle sizes proper to the purpose of users by eliminating a cooling surface on which ice can be deposited easily as in the case of indirect cooling and adjusting a hole size of a water diffusion nozzle and physical properties of an intermediate medium substance. CONSTITUTION:This ice making plant comprises a refrigerator 1 which cools an intermediate medium, such as oil or CFCs and a heat exchanger 2 which heat-exchanges an intermediate medium with refrigerant and an ice making apparatus 3 which manufactures ice d by diffusing water c into the intermediate medium and a heat accumulator 4 which stores the ice d manufactured with the ice making apparatus.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice making facility using an intermediate medium such as oil or freon which is indirectly cooled for ice making.

[0002]

2. Description of the Related Art Most of the ice makers employ a so-called indirect cooling system in which a refrigerant is supplied to one of the heat exchangers and ice brine is supplied to the other of the heat exchangers to make ice. For this reason, a part of the ice-made ice adheres to the cooling surface, grows, and eventually blocks the pipe. Therefore, in order to continue ice making, it is necessary to remove the attached ice.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned drawbacks, and its purpose is not only to provide a cooling surface to which ice is likely to adhere, such as indirect cooling,
An object of the present invention is to provide an ice making facility capable of producing ice with a particle size suitable for the purpose by adjusting the physical properties of the intermediate medium and the hole diameter of the water dispersion nozzle.

[0004]

Means for Solving the Problems The ice making equipment of the present invention which can achieve the above object is a refrigerator for cooling an intermediate medium such as oil and freon, and a heat exchange for exchanging heat between the intermediate medium and a refrigerant. It is composed of a vessel, an ice maker that produces water by dispersing water in an intermediate medium, and a heat storage tank that stores the ice produced by the ice maker.

Thus, a refrigerator for cooling an intermediate medium such as oil or freon, a heat exchanger for exchanging heat between the intermediate medium and a refrigerant, and ice making for dispersing ice in the intermediate medium to produce ice. By including a heat storage tank that stores the ice produced by the ice cooler and ice maker, there is not only a cooling surface such as indirect cooling where ice is likely to adhere, but also the physical properties of the intermediate medium and the hole diameter of the water dispersion nozzle By adjusting, ice having a particle size suitable for the purpose can be produced. Furthermore, since the intermediate medium and water are in direct contact, there is no heat exchange loss.

Here, the intermediate medium is oil, freon,
There is a difference in specific gravity from water such as mercury, and the freezing point is -10.
It is as low as ℃ or less, and does not coagulate near the operating temperature and does not easily mix with water (organic medium,
Any inorganic medium).

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a refrigerator, 2 is a heat exchanger, 3 is an ice maker, 4 is a heat storage tank, and a refrigerant a cooled by the refrigerator 1
Is sent to the heat exchanger 2 through the pipe 5a and exchanges heat with the oil b, and then returned to the refrigerator 1 through the pipe 5b.

Oil b cooled by refrigerant a is pipe 6
It is returned to the ice maker 3 through b. Then, the water c dispersed in the form of droplets from a large number of dispersion nozzles 7 provided in the ice maker 3 is cooled by the oil b while floating in the oil b to become ice d. Oil b in which cold heat is applied to water c
Is returned to the heat exchanger 2 through the pipe 6a and cooled again.

On the other hand, the generated ice d floats to the upper layer of the oil b due to the difference in specific gravity, and then is conveyed to the heat storage tank 4 through the duct 8a. The water c in the heat storage tank 4 is supplied to the ice maker 3 through the pipe 8b. In FIG. 1, 10 and 11 are pumps.

[0010]

As described above, according to the present invention, a refrigerator for cooling an intermediate medium such as oil and freon, a heat exchanger for exchanging heat between the intermediate medium and a refrigerant, and water in the intermediate medium are provided. Since the ice making equipment is composed of an ice maker for dispersing and producing ice and a heat storage tank for storing the ice made by the ice maker, the following effects can be obtained.

By adjusting the physical properties of oil and the dispersion nozzle of water, it is possible to produce ice having a particle size suitable for the purpose. Since oil and water are in direct contact, there is no cooling surface such as indirect cooling where ice is likely to adhere. Therefore, clogging due to adhesion and growth of ice on the cooling surface does not occur. Since it is in direct contact, there is no loss of heat exchange. You can make ice with water without adding additives.
