What kind of environmentally friendly dryer is suitable for you?

From the perspective of occupying the air, due to the merger of the all-in-one machine, it must be more space-saving than the independent type. However, from the perspective of drying efficiency, the independent type dryer has the advantages of fast heating and high drying efficiency because of its single function. If it is divided into detailed drying principles, it can be divided into heating drying and condensation drying. Each has its own strengths. Heating drying is a method of heating to bake the moisture in clothes into the air, and then the air activity reduces the humidity, like the heating principle we usually use to blow hair. The principle of condensation drying is that the humidity formed at low temperature is reduced. When reheated to normal temperature, this process can achieve the purpose of drying.

The dryer is a device used to stop the drying operation. After heating, the moisture in the material (commonly referred to as water or other volatile liquid components) is vaporized and escaped to obtain a solid material with a regular moisture content. The dryer can be divided into four types according to its shape and different uses: rotary dryer, flap dryer, mesh belt dryer, vertical dryer. Different industries have different needs. Choose the right one according to my needs.

The environmental protection dryer is mainly composed of four parts: a finned evaporator, a compactor, a finned condenser, and a throttle valve. After the working fluid is evaporated from time to time, it absorbs the heat from the outdoor environment (or the water vapor in the drying room) → The thermal cycling process of tightening → condensation (releasing heat in the indoor drying room) → throttling → re-evaporation, thereby transferring the heat in the external low temperature environment (or the water vapor in the drying room) to the drying room, and the refrigerant in the The compactor circulates in the system. It completes the gaseous step-up and temperature rise process (temperature up to 100 ℃) in the compactor. It enters the internal machine and releases high-temperature heat to heat and dry the air in the room. At the same time, it is cooled and converted into a liquid state. When it runs to the external machine After that, the liquid rapid endothermic evaporation turns into a gaseous state again, and the temperature can drop to -20 ° C to -30 ° C. At this time, the air around the heat sink will constantly transfer heat to the refrigerant.

When the integrated dryer works, like ordinary air conditioners, it absorbs energy in the medium in the evaporator QA: It consumes a local energy, that is, the power consumption of the compactor QB: When the working fluid circulation system is in the condenser Release heat QC, QC = QA + QB, so the efficiency of the heat pump drying unit is (QB + QC) / QB, so the heating efficiency of the heat pump drying unit is far greater than the efficiency of other heating equipment. It can be seen that the heat pump drying unit is used as the drying installation. It can save energy and save no emissions of CO2 and other pollutants, and achieve the effect of energy saving and emission reduction.
