Description

The air-conditioning system of air source heat pump solid absorption dehumidifying
Technical field
Patent of the present invention relates to the air-conditioning system of a kind of solid absorption dehumidifying, belongs to building energy saving field.
Background technology
The air-conditioning system of the solid absorption dehumidifying of development in recent years, owing to not needing low-temperature heat source to dehumidify, not only energy-conservation but also be conducive to health, using air source heat pump as this technology of the cold and heat source of this system, develop to some extent, but, due to the necessary pair-wise combination of solid adsorption dehumidification device, after its adsorption and dehumidification, regenerative process is also wanted to run continuously, therefore, two cover air source heat pump lists be adopted for dehumidifying service, then uneconomical.How to make two cover heat pumps used both bear room cooling, can bear dehumidifying again, and can realize independent temperature-humidity control, be the problem needing to solve.
Summary of the invention
The present invention, in order to overcome above-mentioned air source heat pump solid absorption dehumidifier shortcoming, proposes following technical scheme: namely by the fin tube bundle A of the bonding silica gel of a pair parallel connection, B, replaces the condenser in an air source heat pump, retains its remaining part, i.e. compressor C, the indoor fluorine of capillary 1 and the evaporimeter as heat pump heat distribution system---air heat exchanger 3, so the heating forming air source heat pump, can realize the heating of silica gel, regeneration, then by the fin tube bundle A of the bonding silica gel of described parallel connection, B, replaces the evaporimeter in another air source heat pump, retains its remaining part, i.e. compressor D, capillary 2 and the outdoor fluorine as its condenser---air heat exchanger 4, form air source heat pump refrigeration system, can realize the cooling of silica gel, described heat pump heats, in refrigeration system, with A in parallel, the inlet tube that B is connected has import threeway 17, 18, outlet has outlet threeway 19, 20, conflux arm and the shunt pipe of each threeway is equipped with magnetic valve, namely magnetic valve 9 is housed on 17, 10, be equipped with 11 on 18, 12, be equipped with 13 on 19, 14, be equipped with 15 on 20, 16, amount to eight.
Eight described magnetic valves, are divided into two groups, periodically open in turn, namely 9,10,11,12 open simultaneously, coordinate compressor C to open, silica gel A regeneration regime can be obtained, after a period of time, 13,14,15,16 open simultaneously, coordinate compressor D to open, silica gel cooling absorption working condition can be obtained.
Described indoor fluorine---air heat exchanger 3 is mounted in air-conditioned room, compressor C suction temperature, pressure can be made higher, thus outlet obtain high temperature, high pressure, meets silica regeneration requirement, meanwhile, indoor fluorine---air heat exchanger 3 is to air-conditioned room cooling.
Solid absorption dehumidifier/air-conditioning system of the present invention is formed by above-mentioned silica gel heating regenerative system and cooling adsorption system summation.
