Problems solved by technology
[0002] At present, the air cooler in the crop fresh-keeping cold air storage is easy to frost, and the cooling effect decreases after frost, and the cold storage does not cool down in severe cases
At the same time, the frosting of the air cooler will also cause the humidity of the cold storage to drop, which will increase the dry consumption of fresh-keeping products and greatly affect the fresh-keeping effect.
Therefore, the existing conventional air coolers need to defrost in time, and defrosting is a process that consumes a lot of energy, and causes a high rise in storage temperature, which is not conducive to the preservation of agricultural products

Embodiment Construction
[0009] The accompanying drawing is an embodiment of the present invention, which includes a refrigeration compressor unit 1, a cooling fan 2, a calandria evaporator 3, etc., and the calandria evaporator 3 is arranged in a shallow pool with a refrigerant at the bottom of the cold storage. One end of the calandria evaporator 3 communicates with the refrigeration compressor unit 1, and the other end communicates with the air cooler 2 installed in the cold storage. The other end is communicated with the refrigeration compressor unit 1, so that the refrigeration compressor unit 1-→ calandria evaporator 3-→ air cooler 2-→ refrigeration compressor unit 1, forming a cycle.
[0010] The refrigerant in the refrigeration compressor unit 1 first enters the calandria evaporator 3 for evaporation and cooling, and then enters the air cooler 2 for evaporation and cooling. In the calandria evaporator 3, part of the refrigerant evaporates, and the steam formed here and the remaining refrigerant...

This invention is a double-evaporators high humidity defrosting-free coldstorage for keeping agricultural product fresh. It includes refrigerating compressor unit, cold air machine and grid evaporator. The grid evaporator is arranged in the shallow pool filled with refrigerating medium. The shallow pool is arranged at the bottom of coldstorage. One end of the grid evaporator communicates to refrigerating compressor unit. The other end communicates to the cold air machine in the coldstorage. The other end of cold air machine communicates to the refrigerating compressor unit. The refrigerating medium firstly enters into the grid evaporator for vaporizing and cooling down. Then, the refrigerating medium enters into cold air machine for vaporizing and cooling down. Spraying device including spraying pipe or pump can be arranged. The spraying pipe is on the surrounding wall of the coldstorage and at the upper side of cold air machine. The spraying pipe communicates to the shallow pool through the pump. This invention can reduce the frosting of cold air machine. It also keeps high humidity and constant temperature of the coldstoage. Thus, it greatly increases the fresh-keeping effect of agriculture product.
Description
1. Technical field: [0001] The invention relates to a double evaporator high-humidity defrost-free refrigerator for keeping agricultural products fresh. 2. Background technology: [0002] At present, the air coolers in the crop fresh-keeping cold air storage are prone to frosting, and the cooling effect decreases after frosting, and the cold storage does not cool down in severe cases. At the same time, the frosting of the air cooler will also cause the humidity of the cold storage to drop, which will increase the dry consumption of fresh-keeping products and greatly affect the fresh-keeping effect. Therefore, the existing conventional air coolers need to defrost in time, and defrosting is a process that consumes a lot of energy, and causes a high rise in storage temperature, which is not conducive to the preservation of agricultural products. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a double evaporator high-humidity defrost...
