Embodiment Construction

[0015] Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

[0016] see figure 1 and figure 2 , The air conditioning system includes: a carbon dioxide supercritical cycle heat pump and a solution cycle system. The cold energy generated by the carbon dioxide supercritical cycle heat pump evaporator is used to produce high-temperature chilled water (15-18°C) to remove the sensible heat load of the building; the heat exhausted by the cooler is used to heat the solution or hot water (the temperature is 80- 90°C) to provide heat for concentration and regeneration of the solution; the concentrated solution is used to remove the latent heat load of the building, thereby realizing independent adjustment and control of temperature and humidity. The dehumidification solution used in the present invention uses lithium bromide, lithium chloride, etc.

Abstract

The inventive air-conditioning system consists of a carbon-dioxide supercritical circulating heat pump and a solution regenerating cycle device. The said heat pump includes a compressor, a cooler, an internal heat exchanger, a throttle valve, an evaporator and a liquid-storage tank. The said solution regenerating cycle device includes a gas-liquid spray module, a solution pump, an air heat regenerator and a plate-type heat exchanger. In the air-conditioning system, the independent control of the moisture-temperature index can be realized because of using the solution system to control the indoor moisture and using the carbon-dioxide supercritical circulating heat pump to control the indoor temperature.

Description

technical field [0001] The invention relates to an air-conditioning system combining a carbon dioxide supercritical cycle heat pump and solution dehumidification, and belongs to the technical field of heating, ventilating and air-conditioning. Background technique [0002] In conventional air-conditioning systems, condensation dehumidification is generally used to adjust the humidity of the air. This dehumidification method needs to cool the air below the dew point temperature to achieve the task of dehumidification. In many cases, further reheating is required to make the air supply parameters reach Although this method can more accurately control the temperature and humidity of the air supply, there is a double energy waste of overcooling and reheating in the process. In many buildings, no reheating device is installed in the air-conditioning system, and the low-temperature air after condensation and dehumidification is directly sent into the room, resulting in low-tempera...
