The method of making ice and storing ice on the ice surface by using cold wind in winter

Abstract

The invention relates to technical fields of ice making and storage and refrigeration, and discloses a method for making and storing ice on an ice surface through cold wind in winter. A rectangular deep underground or semi-underground ice making and storage tank (1) is built, and comprises a concrete-structure tank bottom (2) with a thermal insulating layer, a tank wall (2), a large-span steel-structure tank top (4), a ventilating zone (5), a controllable water spray system (6) comprising a water pump, a water pipe and a spray head, and a thickened zone (7) with adhesives. In winter, cold air is blown into a water tank through the ventilating zone, the water surface begins to be frozen when meeting the cold air, after the water surface is completely frozen, a thin layer of water below ice is uniformly sprayed on the ice surface through the controllable water spray system, cold wind is directly blown to the water surface till water is frozen again, the circulation is continuously operated, and finally water in the tank is completely frozen. After ice is made, light thermal insulation material is used for tightly covering the ice. The method adopts natural cold resource to make ice, improves the ice making efficiency, reduces the cost, reduces manpower and energy consumption, and does not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of ice making and ice storage, in particular to a method for making ice and storing ice on an ice surface by using cold wind in winter. Background technique [0002] It is a good thing for environmental protection and energy saving to turn waste into treasure, and it has always been a good wish of people to store cold resources in nature in winter and use them as cold sources for cooling down in hot weather, or cold sources for fruit and vegetable cold storage. In ancient times, there were records of harvesting ice from rivers and ponds, storing it in ice cellars, and taking it when it was hot. Now in Northeast my country, there is still the original practice of harvesting ice from rivers and rivers in winter to store fruits. In the last 30 years, scientific and technical personnel from many countries in the world have devoted themselves to the research on the utilization of natural cold resources, and have ...

Problems solved by technology

[0009] Aiming at the problems existing in the above-mentioned prior art, the object of the present invention is to propose a method for making ice and storing ice on the ice surface by using the cold wind in winter, which overcomes the problems in the past that either cost a lot of manpower, or consume a lot of energy, or have low ice-making efficiency and low ice-making efficiency. Small amount of ice, or high climatic conditions, can not make large-scale use of natural cold resources to produce ice and store ice
