Heat pump dryer working principle

A heat pump dryer is a device that utilizes heat pump technology for clothes drying. Its working principle is based on the heat pump circulation process and is suitable for drying clothes, bed sheets, towels and other textiles.

The working principle of heat pump dryer is as follows:
1. Compressor: The compressor in the heat pump dryer compresses the work material (usually refrigerant) from a low-temperature, low-pressure state to a high-temperature, high-pressure state. Through the compression of the mass, its internal molecular spacing becomes smaller, and the temperature rises. 2.

2. Evaporator: the high temperature and high pressure of the substance through the expansion valve into the evaporator. In the evaporator, the temperature and pressure of the work material drop, so that it absorbs heat and evaporates. In the process of evaporation, the work material is changed from liquid state to gas state, and the heat absorbed is extracted from the drying articles.

3. Heat exchanger: The moisture in the drying articles is evaporated and turns into moisture gas. The moisture gas flows through the heat exchanger and transfers heat and mass with the moisture in the dried articles to vaporize the moisture in the moisture gas. The condenser on the heat exchanger causes the moisture in the moisture gas to condense into water for subsequent processing.

4. Recompression: After passing through the heat exchanger, the work material enters the compressor in gaseous form. Through recompression, its temperature and pressure are raised again. 5.

5. condenser: after recompression, the mass enters the condenser. Condenser through the external environment of the cooling medium (usually air or water) to make the material cooling. During the condensation process, the mass releases heat and turns into liquid. 6.

6. Expansion valve: the condensed mass through the expansion valve into the evaporator, the cycle back to step 2.

Through the above cycle process, the heat pump dryer can continuously absorb and release heat and extract the moisture from the humidity. The drying items are supplied with sufficient heat in the process, thus realizing a fast and ** drying effect.

To summarize, the principle of the heat pump dryer is to use the heat pump cycle process to complete the treatment of moisture in the moisture in the heat absorption, compression, evaporation, condensation and so on, so as to realize the drying of clothing and other textiles. This type of drying is characterized by **, energy saving and is environmentally friendly, thus it is widely used in homes and commercial places.
