Description
Technical field
Solar energy dehumidifying heating all-in-one machine is a kind of by rotary dehumidifier panelized, directly regenerates adsorbent with solar radiant energy, again can the device of heat collection heating, belongs to field of heating ventilation air conditioning equipment.
Background technology
Along with Urbanization Process In China development, architectural energy consumption constantly increases, and the civil buildings power consumption of Chinese cities and towns accounts for 22% ~ 24% of China's gross generation, and in public building, air conditioning electricity accounts for 50% ~ 60% of total electricity consumption.Along with the lifting of China's living standard, residential electric power amount is also in continuous rising.The efficiency how promoting air-conditioning is the important direction of of research air-conditioning.
In order to maintain indoor good environment, a certain amount of new wind must be passed into indoor.The heavy load that new wind load duty is adjusted in summer is approximately 25% ~ 30%.Be divided into two parts in summer air-conditioning new wind load, a part is reduce the load of air themperature, and a part is except humidity load and latent heat load in addition.At Hot-Humid Area, as Guangzhou, summer of air-conditioning, latent heat load was more than 80% in cooling load from outdoor air, and the ratio accounted at hot-summer and cold-winter area is also more than 40%.The mode of what present air-conditioning often adopted is cooling and dehumidifying, by air by the equipment surface lower than air dew point temperature, water vapor condensation is dehumidified, at this moment require that the temperature of evaporator of refrigerator will lower than air dew point temperature, it reduce the EER of refrigeration machine, if refrigeration machine is only for reducing air themperature during process air, adopt other equipment to remove separately moisture in air, the EER of refrigeration machine can improve, thus improves the efficiency of air-conditioning.Visible, how effectively dehumidifying is very significant research.
Adsorbent dehumidifying is a kind of important method of dehumidifying, and wherein a lot of advantage that to dehumidify with Static Adsorption is compared in Dynamic Adsorption dehumidifying.Dynamic Adsorption dehumidifying is made up of adsorption process and regenerative process, and in regeneration, thermal regeneration is a kind of conventional regeneration.Thermal regeneration needs to consume higher energy traditionally, if adopt solar heat collector and heat reclamation device to reduce energy consumption, but system complex, invest larger.For the rotary dehumidifier adopted normal on HVAC, the equipment of complete set needs two Fans, a motor (driving runner), a regenerative heater (as solar thermal collector) or condenser, a total-heat exchanger and a desiccant wheel.Rotary dehumidifier is widely used now proves that it has lot of advantages, such as its dehumidifying part and regenerating section ratio are approximately 3:1, dehumidifying district and renewing zone can continuous low switchings, but also there are all shortcomings, the flow direction as the regeneration hot blast of rotary dehumidifier and the air of process is contrary, and the heat can't eliminating sorbent during regeneration completely takes dehumidifying district to.The method of thermal regeneration adsorbent uses solar energy heating air traditionally, and hot-air again by adsorbent, thus realizes regeneration, and this needs the air of constantly heating flow, although adopt recuperation of heat, thermal loss is still larger.If only heating and dehumidification agent ambient air is to higher temperature, adsorbent can be resolved completely, and air also can containing more water vapour.Adsorbent bed in adsorption refrigeration system is a kind of device using adsorbent as absorber, can absorb sunshine by day, and after temperature raises, adsorbent just starts to resolve, and this Technology application is in the utility model.
Summary of the invention
