Constant-temperature and constant-humidity defrosting and refrigerating device

Abstract

The constant-temperature and constant-humidity defrosting and refrigerating device comprises a box body, and a variable-frequency compressor and a condenser are installed at the bottom end of the box body; the evaporator assembly is assembled in the box body, and the evaporator assembly comprises but is not limited to a roll-bond evaporator and a fin evaporator; according to the technical key points, switching control over the multiple evaporators adjusts the frequency of a variable-frequency compressor according to the sizes of the different evaporators, and it is ensured that in the switching process, the temperature in a box can be maintained, and a fan can drive air flow to pass through frost layers on the surfaces of the evaporators to be removed in cooperation with the actual temperature and the operation time of the compressor after frequency modulation; the humidifying device is of a combined structure, a high-temperature refrigerant flows through the heating pipe and is attached to the metal water tank, the water temperature in the metal water tank is higher than the temperature in the refrigerating chamber, the humidifying effect of the wet film net can be effectively improved, and it can be guaranteed that the interior of a product does not freeze when the temperature reaches 0 DEG C; the whole device has the characteristics of safety, stability, effectiveness and easiness in control.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, in particular to a constant temperature and humidity defrosting refrigeration device. Background technique [0002] The existing constant temperature and humidity refrigeration products are mainly refrigeration products that have strict requirements on humidity and temperature, such as meat moisturizing and storage of cigars. The temperature range required by the product is 0~25 degrees, and the humidity requirement is between 55~85; The products are all equipped with an evaporator in a single room. When the product is running and cooling by the compressor, it is equivalent to dehumidifying the product, resulting in a decrease in the humidity fluctuation in the product space. After reaching the cooling temperature, it needs to be stopped immediately. system, it is easy to cause frost and ice on the surface of the evaporator, and regular defrosting is required; at present, the defrosting of ...

Problems solved by technology

Using ultrasonic atomization and oscillation humidification, the humidification speed inside the product is fast, but the disadvantages are that the water molecule particles are large, the control is not precise, and the service life of the ultrasonic wave is affected, which is unreliable; the disadvantages of using wet film immersion and fan blowing are: slow humidification, When the water temperature is below 5 degrees, the humidification will lose its effect
