Embodiment Construction
[0023] see in conjunction Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, the heat pump system includes a fan 1, a refrigerant circulation circuit and a heat storage circuit, the refrigerant circulation circuit includes a compressor 2, an evaporator 3, a condenser 4 and a first throttling device 5, and the heat storage circuit The heat storage device is included, and the heat storage device is used to absorb the heat of the compressor 2 and / or the fan 1, the refrigerant flows through the heat storage circuit, and transfers the heat absorbed by the heat storage device to the refrigerant circulation circuit.
[0024] The heat pump system can recover the heat of the compressor 2 and / or the fan 1, which is energy-saving and environmentally friendly. It can also use the heat to heat the refrigerant, thereby reducing the heat that the evaporator needs to absorb, and effectively solving the problem of system startup and low environment. Insuffici...

The invention provides a heat pump system and a drying device of a heat pump. The heat pump system comprises a draught fan (1), a refrigerant circulating loop and a heat accumulation loop, the refrigerant circulating loop comprises a compressor (2), an evaporator (3), a condenser (4) and a first throttling device (5), and the heat accumulation loop comprises a heat accumulation device; the heat accumulation device is used for absorbing heat of the compressor (2) and / or the draught fan (1), a refrigerant flows through the heat accumulation loop, and heat absorbed by the heat accumulation deviceis transmitted to the refrigerant circulating loop. According to the heat pump system, the problems that in the starting stage, heating of the drying device is not enough in the running state at thelow environmental temperature, and the frosting phenomenon occurs on the evaporator, so that heat exchange is influenced are solved.
Description
technical field [0001] The invention belongs to the technical field of drying equipment, and in particular relates to a heat pump system and a heat pump drying device. Background technique [0002] At present, the air circulation of most existing heat pump drying devices is roughly as follows: the air heated by the condenser in the heat pump system is sent into the clothes drying room by the fan, and the hot and humid air after heat and moisture exchange with the wet load is sucked back to the evaporator The dehumidified air is heated by the condenser again and sent to the drying room, so that the cycle is repeated to achieve the dehumidification and drying effect. [0003] The heat pump system of the existing heat pump drying device is mostly composed of a compressor, a condenser, a throttling device, and an evaporator connected in sequence. The drying device using this heat pump system is the simplest and most basic. Although it is simple and easy to implement, it has gre...
