High-pressure refrigerant-driven refrigeration and purification integrated machine and method

Abstract

The invention relates to a high-pressure refrigerant-driven refrigeration and purification integrated machine and a method, and belongs to the field of safety lifesaving. The machine is characterized by mainly comprising a high-pressure storage tank device, a cooling dehumidification device, an air purifying device and a water storage device. According to an air conditioning and purifying method of an non-electric air conditioning and purifying system, the method is characterized by comprising the following steps that: high-pressure liquefied gas in a high-pressure gas tank passes through a reducing valve, a primary evaporator, a hand valve, a pneumatic fan and a secondary evaporator to cyclically reduce temperature and dehumidify surrounding air. Due to the negative pressure effect of the pneumatic fan, air enters from an air inlet of the air purifying device, and then enters an air duct after being purified by an air purifying agent, a condensate water tray is used for collecting condensate water of the primary evaporator and the second evaporator, and the condensate water can flow into a collecting tank for use through a water purifier. Compared with a conventional mine escape capsule refrigeration and purification system, the high-pressure refrigerant-driven refrigeration and purification integrated machine has the outstanding advantages of strong heat transfer, excellent economic performance and simplicity in installation and maintenance.

Problems solved by technology

However, the design and research of the rescue chamber in our country is in its infancy, and the key technologies of the rescue chamber need to be further studied and explored, especially in the design of refrigeration, air purification and other systems, there are still many technical problems

At present, the cooling methods suitable for the rescue chamber mainly include ice storage refrigeration, electric storage refrigeration and high-pressure air source refrigeration, etc. Among them, ice storage refrigeration has a high failure rate of ice making equipment, which is not conducive to long-term use, and the power of the purification equipment remains low. Electricity storage is needed to guarantee; electric storage refrigeration needs to carry a large volume of explosion-proof battery, which is expensive, and the excessive operating current brings great difficulties to explosion-proof, and the refrigeration performance is easily affected by the outside world, which is not conducive to popularization and use; therefore , on the basis of ensuring good cooling and purification effects, how to achieve energy saving, environmental protection, and economical effects is the key to system design
