Solution dehumidification/regeneration heat and moisture independent treatment air conditioning device and energy-saving operation method thereof

Abstract

The invention discloses a solution dehumidification / regeneration heat and moisture independent treatment air conditioning device and an energy-saving operation method thereof. The solution dehumidification / regeneration heat and moisture independent treatment air conditioning device consists of a solution dehumidification / regeneration device, a dual-evaporator / dual-condenser compression-type refrigeration heat pump unit which is driven by a dual-air-suction-pressure compressor, and a radiating coil, wherein refrigerant is divided into two paths after flowing from an outlet of the dual-air-suction-pressure compressor, one path enters the dual-air-suction-pressure compressor from a first input end, the other path enters the dual-air-suction-pressure compressor from a second input end; cold water is sent to a second water cooling evaporimeter from a water pump, a water oulet of the second water cooling evaporimeter is connected to a water inlet of a second liquid-liquid heat exchange, the water outlet of the second liquid-liquid heat exchanger is connected to the radiating coil, a back-water valve is arranged on a back-water pipeline of the radiating coil, and a branch provided with a third valve is arranged between a cold water supply pipe and the back-water pipeline. The system can operate at lower concentration of dehumidifying solution, the solution regeneration demand can be met by using condensation heat and the energy saving effect of the system is more remarkable.

Description

technical field [0001] The invention relates to a heat-moisture independent treatment air-conditioning system with solution dehumidification and regeneration, application of double-suction pressure compressors, and radiant coil cooling, as well as its energy-saving operation mode and scheme, belonging to the technical field of refrigeration and air-conditioning system design and manufacture. Background technique [0002] With the diversification of building functions and the continuous increase of population density, the energy consumption of building air-conditioning is also increasing, and reducing the energy consumption of air-conditioning systems has become an important measure for building energy conservation. At present, the air-conditioning system used in large quantities consumes a large amount of electric energy and causes serious environmental pollution problems due to its own structure and defects in air treatment methods. Therefore, it is more urgent and practical...
