Regenerative evaporative cooling air conditioner

Abstract

The invention relates to a regenerative evaporative cooling air conditioner belonging to the technical field of refrigeration engineering. The air conditioner comprises a multi-stage rotor dehumidification subsystem and an evaporative cooling subsystem which are mutually connected in series. The rotor dehumidification subsystem comprises a dehumidification rotor, a motor, a transmission mechanism, a reheater, a heater and a regeneration fan. The evaporative cooling subsystem comprises a precooler, an evaporative cooler, an indoor heater exchanger, a cooling water pump, an evaporative cooling fan and an indoor heater exchanger fan. The air conditioner realizes the efficient processing on latent heat and sensible heat load and improves air conditioning energy efficiency by utilizing the driving of regenerative energy, such as exhaust residual heat, solar energy and the like, and combining with the advantages of the isoenthalpic dehumidification of rotor dehumidification and the isohumidity cooling of regenerative evaporative cooling. The air conditioner is simple in structure, accurate in control and environment friendly. The air conditioner is completely driven by low grade heat sources, which is instrumental in building health and comfortable living environments. The invention provides a green energy-saving type refrigeration unit.

Description

technical field [0001] The invention relates to a device in the technical field of refrigeration engineering, in particular to a regenerative evaporative cooling air conditioner. Background technique [0002] Rotary dehumidification and air conditioning technology uses air and water as working fluids, driven by low-grade heat sources such as solar energy, and uses the hydrophilicity of desiccant to achieve heat and humidity treatment. This technology not only effectively avoids the problems of power consumption and CFC refrigerant, but also helps energy conservation and environmental protection. It also overcomes the shortcomings of conventional air-conditioning dew point dehumidification, and can realize independent control of temperature and humidity, thereby creating a healthy and comfortable living environment. Therefore, the development of new and efficient rotary dehumidification air-conditioning technology is of great significance for improving the thermal environment...
