Open temperature and humidity independently control the solar direct -drive air -conditioning system and its working method

Abstract

The invention provides an open independent temperature and humidity control solar direct-driven air conditioning system. The open independent temperature and humidity control solar direct-driven air conditioning system comprises one of a dew-point type evaporative heat exchanger (2) and an indirect evaporative cooler (7), a runner (1), a solar photovoltaic and photothermal integrated component (3), a condensing heat exchanger (4), a first water pump (5), a first draught fan (8) and a second draught fan (9), wherein a first air outlet of the runner (1) is connected to an inlet of a first flow channel of one of the dew point type evaporative heat exchanger (2) and the indirect evaporative cooler (7); and a second air outlet of the runner (1) is connected to an inlet of a first flow channel of the condensing heat exchanger (4). The invention also provides a working method of the air conditioning system. The air conditioning system provided by the invention completely depends on solar energy to realize the air conditioning of buildings in summer; spray water required for air supply cooling is self-sufficient by the system; and the air conditioning system reduces the consumption of electric power and water resources and alleviates the pressure of the power grid.

Description

technical field [0001] The invention belongs to the field of air-conditioning systems, and in particular relates to an open solar direct-drive air-conditioning system with independent temperature and humidity control and a working method thereof. Background technique [0002] With the progress of society and the improvement of living standards, residents have higher and higher requirements for thermal comfort of buildings. Air conditioning is still the most common cooling method in summer, but the power consumed by its operation has increased the burden on the grid, and its dehumidification function requires additional energy consumption. At present, three new refrigeration methods using solar energy as the main energy source have been proposed, including solar air-conditioning, solar-driven dehumidification system and solar-driven adsorption refrigerator. The solar air conditioner adopts indirect utilization of solar energy, that is, converts solar energy into electrical e...

AI Technical Summary

Problems solved by technology

The solar air conditioner adopts indirect utilization of solar energy, that is, converts solar energy into electrical energy through photovoltaic panels, and the utilization efficiency is low, and the price of photovoltaic panels is relatively expensive; the solar-powered rotary dehumidification system can realize independent control of temperature and humidity, but The air temperature is relatively high, and it needs to be cooled by a cooling heat exchanger, which consumes a large amount of spray water; the solar-driven adsorption refrigerator uses the evaporation and heat absorption of the working fluid in the evaporator during the adsorption process to achieve cooling of the building, but the indirect heat transfer efficiency is low. And does not have dehumidification function, the system structure is complex

The above-mentioned electric-driven air conditioners and the current three solar-powered air-conditioning technologies cannot take into account energy saving and emission reduction as well as effective regulation of temperature and humidity.
