technical field

The invention belongs to the application field of heating, ventilating and air-conditioning technology, and relates to an indoor thermal comfort adjustment and system energy-saving process, in particular to a solar energy winter and summer solid humidity control system.

Background technique

In the world's growing energy consumption, building energy consumption accounts for a large proportion of the total energy consumption of each country, and building energy consumption in developed countries accounts for about one-third of their total energy consumption. In my country, the operating power consumption of urban civil buildings (non-industrial buildings) accounts for 22-24% of my country's total power generation, and the coal consumption for heating in cities and towns in northern China accounts for 15-18% of my country's non-power generation coal consumption. It accounts for 21-24% of the national commodity energy. With the continuous improvement of the degree of urbanization in my country, the increase of the proportion of the tertiary industry in GDP and the adjustment of the manufacturing structure, the proportion of building energy consumption will continue to increase and will approach the level of developed countries.

In particular, my country's energy consumption per unit building area is 2 to 3 times that of developed countries, causing a heavy energy burden and serious environmental pollution to the society. According to relevant data, the total area of China's existing buildings is more than 40 billion m2, and it is estimated that by 2020, the new building area will be about 30 billion m2, and the building energy consumption will reach more than 1/3 of the country's total energy consumption. It can be seen that, Building energy consumption will have a long-term and huge impact on my country's energy consumption.

The distribution of solar radiation in northern my country is very rich. Taking Xi'an as an example, Xi'an is located at the southern end of the cold region in the thermal division. The average temperature of the coldest month is 0-10°C. The heating period lasts for four months, and the energy consumption for heating accounts for 50% of the energy consumption of the entire building. The daily average total radiation during the heating period can reach 5-10MJ/m ² , and solar energy has important utilization value. However, solar energy is an unstable energy source, which is greatly affected by factors such as seasons, weather, and geography during use, especially at night, and cannot provide sufficient and continuous energy supply. At present, the biggest obstacle to large-scale thermal utilization of solar energy is that the acquisition of solar energy is subject to climatic factors, and it cannot supply heat stably around the clock. Solar heat storage technology uses the phase change heat storage of heat storage materials, which can effectively reduce the volume required for energy storage and realize the full and continuous and stable utilization of solar energy. It is a good way to solve this problem.

Solid dehumidification technology is the key to the realization of temperature and humidity separate control technology, and it is also one of the important directions for the development of HVAC. The existing solid dehumidification is mainly used in the total heat recovery device, which recovers the latent heat while recovering the sensible heat in the room. The recovery amount is limited, and it is required to be used in the air conditioning system with return air. At present, the commonly used dehumidification method in the HVAC industry is freezing dehumidification, which has a good effect, but it needs to be prepared by electric-driven refrigeration units or absorption refrigerators driven by gas, steam, and high-temperature hot water, and it also needs to consume high-quality energy. Solution dehumidification is a relatively advanced dehumidification technology that has developed rapidly in recent years and has a good dehumidification effect. However, solution dehumidification generally has a large volume and requires large power consumption or hot water above 80°C to achieve regeneration.

The Chinese patent application number 201110209559.1 discloses a rotary dehumidification air conditioning system using heat pipe heat recovery and ultrasonic enhanced regeneration. Carry out recycling and use ultrasonic enhanced regeneration technology to reduce the requirements of the dehumidifier on the regeneration air temperature of the runner dehumidifier, so as to achieve energy saving of the dehumidification air conditioning system. and system work is more complex. The Chinese patent with the application number 200710045901.2 discloses a two-stage dehumidification and air-conditioning device using low-grade heat sources in the field of refrigeration and dehumidification technology. The system performs humidity and temperature processing on outdoor fresh air or indoor return air. The first-stage dehumidification rotor and the second-stage dehumidification rotor are completed, and the temperature treatment is mainly completed by a heat exchanger and an evaporative cooler. This system can realize continuous operation of dehumidification, which involves a low-grade heat source, but it is not described and utilized in detail. The Chinese patent application number 201210417716.2 discloses a solar dehumidification air conditioning system with energy storage effect. The system uses a solid dehumidifier energy storage bed to store solar energy, and the solid dehumidification energy storage bed uses the dehumidifier to absorb potential energy to convert and heat the air. Storage across seasons requires a large volume and limited heat storage. The Chinese patent with application number 201010252741.0 discloses a solid adsorption dehumidification device, which only designs the internal structure of the solid dehumidification device: it includes a vertical air duct, a dehumidification base arranged therein, a heat source, a cold source, and the dehumidification base includes multiple Finned tubes arranged vertically, multiple flat fins in longitudinal contact with each finned tube, and silica gel adsorbent bonded on the surface of the substrate; the heat source is connected to the dehumidification substrate to form a hot water circuit; the cold source is connected to the dehumidification substrate A cold water circuit is formed; the hot water circuit and the cold water circuit work alternately through the opening and closing of the valve. The Chinese patent with application number 201220638809.3 discloses an absorption refrigeration and solid wheel dehumidification air conditioning system based on solar heat recovery. It is an air conditioning system that integrates solar heat recovery, absorption refrigeration and solid wheel dehumidification.

The refrigerant water prepared by the evaporator is used to cool the dehumidified air. The low-temperature energy storage of the first-level solar collector of the system The liquid medium in the tank is water, and the temperature is in the range of 92-97°C. The liquid medium in the high-temperature energy storage tank of the secondary solar collector is nano-heat transfer fluid, and the temperature is in the range of 180-200°C.
