Drying machine

Abstract

The invention discloses a drying machine. The drying machine comprises a cold pump, a hot pump and a compressor, wherein the cold pump is used for absorbing heat and moisture of fabrics, and a workingmedium passing through the cold pump has first humidity and a first temperature; the hot pump is used for receiving the working medium passing through the cold pump and exhausting heat to air, and the working medium has second humidity and a second temperature after passing through the hot pump; the first temperature is higher than the second temperature, and the first humidity is higher than thesecond humidity; the compressor is used for receiving the working medium of the cold pump, and compressing the working medium to be working medium steam with a high temperature and high pressure, andthe compressed working medium is supplied into the hot pump so as to increase heat for the fabrics. According to the drying machine, a hot pump principle is utilized to conduct dehumidification and heat absorption, therefore the fabrics are dried, compared with an electrical heating mode for drying, the cost of the drying machine is low. The condensation efficiency is improved, and a large amountof heat can be obtained by using few electric energy. The temperature can always be controlled to be constant, it is ensured that fabric fibers do not deform, and the fabrics are prevented from beingdamaged. Energy sources can be saved, 66% of energy can be saved by the drying machine, compared with common drying, meanwhile, the emission load of pollutants such as CO2 is reduced, the environmental protection requirements are met, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of thermal cycle, in particular to a dryer. Background technique [0002] Traditional fabric dryers are widely used for drying all kinds of clothing (clothing, bedding, beds, cushions) and textile materials. Most of them use electric heating or steam heating, and the drying cost is high; the drying temperature cannot be guaranteed to be constant. The emission of pollutants such as CO2 is high, and it cannot be widely used in the market. Contents of the invention [0003] Aiming at the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a dryer. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the embodiments of the present invention is: [0005] A dryer comprising: [0006] A cold pump, which is used to absorb the heat and moisture of the fabric, and the working fluid passing through t...
