Frostless ice house

Abstract

A small and medium frostless refrigeratory for keeping fresh of farm and sideline products is provided, which comprises a refrigeration compressor unit (1), a vaporize comb (2) and a reducing valve (3). The vaporize comb (2) is communicated with the refrigeration compressor unit (1) to form circulation, which is provided with the reducing valve (3); the vaporize comb (2) is arranged in a shallow pool (5) at bottom of a refrigeratory (4); the shallow pool (5) is internally provided with secondary refrigerant. The refrigeratory (4) is also internally arranged with a circulating pump (6) and a cascade device of a shower (7). The refrigeration compressor unit (1) sends the refrigerant to the vaporize comb (2) through the reducing valve (3) and the refrigerant can return to the refrigeration compressor unit (1) after absorb heat; the circulating pump (6) sends the secondary refrigerant to the shower (7) to spray in the refrigeratory (4). The invention is characterized in that: the cold volume is completely exchanged in the refrigeratory, so the invention has no dissipation and lose, large cold volume storage and is able to maintain a relative constant temperature of the refrigeratory, thereby reducing the times for opening and closing the refrigeration compressor, saving energy, prolonging the service life of the equipment, having no forest and high humidity, etc.

Description

1. Technical field: [0001] The invention relates to a small and medium-sized frost-free cold storage for storing and keeping agricultural and sideline products fresh. 2. Background technology: [0002] At present, in the small and medium-sized cold storages used for the storage and preservation of agricultural and sideline products, the evaporative refrigeration equipment in the cold room mostly uses air coolers and various forms of pipes, mainly through air convection heat exchange, the evaporator is easy to frost, and the humidity in the storage is low, which cannot reach To meet the requirements of high-humidity storage and fresh-keeping environment for fruits and vegetables. Using the method of humidifying in the warehouse can make the frosting of the evaporator more serious, and the cooling efficiency is greatly reduced, and the humidification effect is not ideal. The high-humidity cold storage designed with the principle of brine indirect cooling requires complex cons...

Problems solved by technology

[0002] At present, in the small and medium-sized cold storages used for the storage and preservation of agricultural and sideline products, the evaporative refrigeration equipment in the cold room mostly uses air coolers and various forms of pipes, mainly through air convection heat exchange, the evaporator is easy to frost, and the humidity in the storage is low. Requirements for high-humidity storage and fresh-keeping environment for fruits and vegetables

Using the method of humidifying in the warehouse can make the evaporator frost more serious, and the cooling efficiency is greatly reduced, and the humidification effect is not ideal

High-humidity cold storage designed with the principle of brine indirect cooling, the construction and installation of brine equipment and storage tanks outside the storage are complicated, requiring good heat insulation conditions, so the loss of cooling capacity is large and the cooling efficiency is low
