Open low-temperature heat source refrigerating system

Abstract

The invention belongs to the technical field of air conditioners and refrigerating engineering, and relates to an open low-temperature heat source refrigerating system device which combines solution heat transfer and mass transfer processes and heat pipe energy-saving technology and implements refrigeration by using solar energy, geothermal energy, various excess heats, waste heat and the like. Eleven subsystems of open air flow, N-stage solution treatment, Q-stage heat pipe cold reclamation, N1-stage water circulation, solution flow and storage, M-stage solution regeneration, P-stage heat pipe regenerative heat, L-stage air cooling tower, cooling water circular flow, frozen water circulation and temperature control are organically communicated with a low-temperature heat source to form an integrated low-temperature heat source refrigerating system, wherein the N is more than or equal to 1 and less than or equal to 20, and the N, the Q, the N1, the M, the P and the L are equal. The device has the advantages of low power consumption in the cooling process, high COP, simple machining and manufacturing process, stable system operation, safety and reliability, and is widely applied tothe places needing cold energy such as industry, house and the like.

Description

Technical field: [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering, and relates to a high-efficiency heat and mass transfer process realized by direct contact between a solution and air and a heat pipe energy-saving technology to realize open-type heating by solar energy, geothermal energy, various waste heat, waste heat, etc. Low temperature heat source refrigeration system device. Background technique: [0002] Refrigeration systems are widely used in industry, commerce and people's family life and other fields. For example, central air conditioners in industrial and commercial fields, and various air conditioners used in people's home life are also inseparable from refrigeration systems. The energy consumption of the refrigeration system is very huge. According to statistics, the total energy consumption of buildings in my country reached 350 million tons of standard coal in 2002, accounting for 27.6% of the total energ...

Problems solved by technology

At present, there are three main ways to realize refrigeration systems using low-temperature heat sources: absorption refrigeration, jet refrigeration and solid adsorption refrigeration. Although people have a long history of research on these refrigeration methods, these refrigeration methods are for 50- For the refrigeration process of a low-temperature heat source at 80 °C, due to the low COP of the performance coefficient and the vacuum environment in the closed system is easily damaged and cannot operate normally, it has not been widely used.
