Abstract

The invention belongs to the technical field of refrigeration equipment and particularly discloses an all-fresh-air frostless low-temperature air cooler. The air cooler comprises a heat exchanger. A refrigeration air inlet and a defrosting cold-air outlet are formed in the left end of the heat exchanger from the top to the bottom successively. A defrosting air inlet and a refrigeration air outlet are formed in the right end of the heat exchanger from the top to the bottom successively. The heat exchanger is connected with a first air channel and a second air channel are connected with the heat exchanger. One end of the first air channel is connected with the refrigeration air inlet, and the other end is connected with the defrosting air inlet. One end of the second air channel is connected with the defrosting cold-air outlet, and the other end is connected with the refrigeration air outlet. A first three-way valve is arranged at one end of the first air channel, which is close to the refrigeration air inlet. A second three-way valve is arranged at one end of the second air channel, which is close to the refrigeration air outlet. The air cooler is simple in structure, good in cooling effect and capable of not stopping the machine during defrosting, saving energy and improving the efficiency.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an all-new air frost-free low-temperature air cooler. Background technique [0002] As we all know, refrigeration equipment with a refrigeration temperature below zero must be shut down to defrost after a period of operation, and the heat exchanger of the refrigeration equipment cannot exchange heat efficiently without defrosting. [0003] At present, the traditional low-temperature refrigeration equipment such as cold storage is to set the heat exchanger in a closed space, and the cooling is done through the finned evaporator and the fan, so that the air in the storage and the evaporator are repeatedly contacted and circulated to cool down. This type of equipment circulates in a closed space, so the moisture entering the storage is limited, but when the personnel open the cold storage door, humid air will also enter the storage, and when the humid air...
