Problems solved by technology

Among them, refrigeration and ice-making units (or dual-working condition units) have complex structures, high investment, and large floor space; ethylene glycol (or ethylene glycol-like) refrigerants are required for ice-making conditions, which increases the initial investment and the risk of leakage , in the cold storage mode, the efficiency of the refrigeration host is about 60-70% of that of the air conditioner, and the efficiency attenuation is relatively large. Generally, the heat removed by refrigeration is converted into waste heat and released to the environment, which intensifies the urban heat island effect

Embodiment Construction

[0081]The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0082] Such as figure 1 , a spray-type artificial snow-making refrigeration and storage system, including

[0083] (1) Air filter

[0084] Using a renewable molecular sieve air filter, the air in the atmosphere is directly sucked in as the working medium raw material, and the filtered air is pressurized by the compressor:

[0085] ① Dust (> 2μm) filtration efficiency ≥ 95%;

[0086] ② Remove H 2 O.CO 2 、C x h y Wait for VOC;

[0087] ③The filtered air enters the compressor.

[0088] (2) Compressor

[0089] The core power device of this system provides negative pressure for the air sucked by the filter, provides pressure for the working fluid in the injection process, and produces domestic hot water by-product.

[0090] ① Compress the purified air (or circulated dehumidified air) to 0.45MPa;

[0091] ② Use tap water for indirect heat exchange to cool...

Abstract

The invention discloses an injection type artificial snow-making refrigeration and cooling storage system which comprises an air filter, a compressor, a heat exchanger, an ejector, a separator, a cooling storage chamber, a moisture ejector, a cold release heat exchanger and a heat storage water tank. The injection type artificial snow-making refrigeration and cooling storage system consumes a small amount of electricity to drive the compressor, through an injection and ejection system, heat in water (ice) is transferred to domestic hot water, cooling capacity is provided for the outside, and at the same time domestic hot water can be produced incidentally.

Description

technical field [0001] The invention relates to a refrigeration storage system. Background technique [0002] Traditional cold storage is mainly divided into ice cold storage and water cold storage according to the cold storage medium. Among them, water cold storage mainly stores and releases cold energy in the form of temperature difference of water, which is sensible heat cold storage, and the cold storage density is only 2-3.5RTh / m 3 ; Ice storage mainly stores or releases cold energy in the form of ice-water phase transition, which is latent heat storage, and the storage density can reach 10-14RTh / m 3 . Because the cold storage density of water cold storage is relatively small, the mainstream cold storage is mainly ice cold storage. Static ice storage has the disadvantages of high thermal resistance in the ice-making process, small specific surface area and low speed in the ice-melting process; dynamic ice storage has disadvantages such as poor operational stability, c...
