Problems solved by technology

Therefore, dryers are widely used in production, but while the existing dryers are heating, a large amount of cold air generated is not recycled, but is directly discharged into the atmosphere, resulting in waste of resources and environmental damage. influences

Embodiment Construction

[0011] Such as figure 2 As shown, an air energy heat pump drying and refrigeration system includes a drying room 21, a cold storage room 26, an airtight room 23 and an air energy heat pump 27. The outlet is communicated with a closed room 23 through a connecting pipe, and the evaporator 11 of an air source heat pump 27 is arranged in the closed room 23 , and the cold air outlet 24 of the closed room is communicated with a refrigerating room 26 through a pipe 25 .

[0012] according to figure 1 It can be seen that the air energy heat pump 27 includes an evaporator 11, a condenser 12, a compressor 13 and an expansion valve 14. By allowing the working medium to continuously complete evaporation (absorb heat from the outdoor environment)→compression→condensation (in the indoor drying room release heat in the middle) → throttling → re-evaporation thermodynamic cycle process, so as to transfer the heat in the external low-temperature environment to the drying room 21, and the refr...

Abstract

The invention designs a drying refrigeration system for an air-source heat pump. The drying refrigeration system comprises a drying room, a refrigerating chamber, a sealed chamber and the air-source heat pump. A moisture exhaust pipeline is arranged in the drying room. An outlet of the moisture exhaust pipeline is communicated with the closed chamber by means of a connecting pipe. An evaporator of the air-source heat pump is arranged in the sealed chamber. A cold air outlet of the sealed chamber is communicated with the refrigerating chamber by means of a pipeline. The drying refrigeration system for the air-source heat pump has following beneficial effects: the long-term problem in a drying field that moisture exhaust gas is discharged to the atmosphere is solved such that residual cool of a dyer after heating operation is recycled for utilization; refrigeration cost is saved; and the drying refrigeration system is applicable to storage of agricultural seeds and refreshment and refrigeration of agricultural and sideline products and can be used for the field of industry and other mechanical manufacture fields and is in accord with the national policy of energy conservation and emission reduction and has obvious advantage.

Description

Technical field [0001] The invention relates to an air energy heat pump drying and refrigeration system. Background technique [0002] In agricultural production, many agricultural products such as Chinese herbal medicines, vegetables, meat, melons and fruits, etc. need to be dried in the sun. However, the ordinary drying time is long and the number of times of drying is high, resulting in long production cycle and high labor costs. It has become a stumbling block restricting the development of agricultural industrialization. Under this background, the dryer technology plays a vital role in solving the drying and drying technology; similarly, the dryer can also be used in building materials, textiles, leather, ceramics, electroplating industries and other fields. Therefore, dryers are widely used in production, but while the existing dryers are heating, a large amount of cold air generated is not recycled, but is directly discharged into the atmosphere, resulting in waste o...
