A control method and control device for a heat pump-type double-circulation hot-air drying system, relating to a device for supplying or controlling air or gas for drying solid materials or products, and in particular to a control method and control device for a heat pump-type hot-air drying system. The method comprises: configuring a temperature control parameter, and saving a preset temperature control curve parameter; detecting and monitoring an outlet air temperature, and the temperature and humidity of a drying room; dynamically adjusting a set temperature according to a preset temperature control curve; and selecting, according to a current set temperature, a double-circulation dynamic operation mode of a system. The control device uses a micro-processor to realize program control. By building an inner circulation loop for large-volume air circulation, the latent heat of condensation in a refrigerant is fully absorbed, to improve the basic air temperature.

Control method and control device for variable-frequency and variable-capacity heat pump hot-air drying system

Disclosed is a cold energy recovery-type variable-capacity air-source heat pump system, relating to combined heating and refrigerating systems running in an alternating or synchronous manner, wherein a first subsystem and a second subsystem share a double-channel variable-capacity heat exchanger; a heat exchanger main body includes two manually independent refrigerant pipe pass channels, and a refrigerant in the two channels synchronously carries out heat exchange with hot medium water in a shell pass channel; the shell pass channel establishes a water-medium heat-supplying circulation via a hot water circulation pipeline and a hot water circulation pump; the first subsystem and the second subsystem are connected to the two refrigerant pipe pass channels via a control valve group.
