Double-source type high-temperature heat pump drying equipment

Abstract

The invention discloses double-source type high-temperature heat pump drying equipment. The double-source type high-temperature heat pump drying equipment comprises a compressor, a condenser, a throttle valve, a primary evaporator, a fin heat exchanger, a shell-and-tube heat exchanger, a ventilation pipeline, a PTC ceramic heater, an air supply fan, a solar heat collector, a solar hot water circulating pump, a circulating heat pump, a heat storage water tank, a first electric valve and a second electric valve, wherein an outlet of the compressor, the condenser, the throttle valve, the primaryevaporator, the first electric valve, the shell-and-tube heat exchanger and an inlet of the compressor are sequentially connected, the connecting end of the primary evaporator and the first electric valve is connected with an inlet of the fin heat exchanger through the second electric valve, and an outlet of the fin heat exchanger is connected with the inlet of the compressor. According to the double-source type high-temperature heat pump drying equipment, the double heat sources adopted are solar energy and air energy and both are clean energy sources, the combined operation efficiency is high, and no pollution is generated to the environment.

Description

technical field [0001] The invention relates to a dual-source high-temperature heat pump drying equipment. Background technique [0002] At present, traditional drying equipment generally uses a single heat source, which has low efficiency, and the single heat source is easily affected by the outdoor environment, the operation of the equipment is unstable, and the quality of the dried object is poor; The temperature of the air outlet is limited, and the maximum can only reach 70°C. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a dual-source high-temperature heat pump drying equipment. The dual heat sources used are solar energy and air energy, both of which are clean energy sources. The joint operation efficiency is high and the environment is not polluted. And the outlet air temperature can reach above 85°C. [0004] The technical solution to achieve the above purpose is: a dual-source hig...
