Description

Technical Field

[0001] The utility model relates to the field of refrigeration equipment, in particular to a granary refrigeration equipment with moisturizing and water-retaining functions. Background Art

[0002] A low-temperature environment is very important for grain storage. However, the existing warehouse air conditioners can continuously provide low-temperature air during internal circulation. However, the water vapor in the air in the granary will continue to condense into condensed water when it encounters the evaporator, making the air humidity in the granary lower and lower, and eventually causing the grain on the surface of the granary to be completely dehydrated. It is unable to maintain the air humidity and grain moisture in the granary.

[0003] Utility model patent application number 202122662070.1 provides an integrated warehouse air conditioner. This system uses a water pan to collect condensed water from the evaporator and drain it into a vaporizer. An ultrasonic atomizer installed in the vaporizer atomizes the condensed water into atomized water vapor, which is then transported to the blower. The atomized water vapor mixes with the cold air and is then delivered into the grain bin. However, there are the following problems: 1. The amount of atomized water vapor replenished cannot be adjusted based on the humidity of the return air; 2. As the cold air circulates longer inside the granary, the humidity of the return air from the refrigeration equipment decreases, and the condensed water also decreases, making it impossible to maintain normal atomization requirements.
