Description

Air conditioning method with passive cooling of internal air water circulation and device thereof

The invention relates to the technical field of HVAC, and is an air conditioning method and device with passive cooling of internal air water circulation, which is suitable for air conditioning of various living buildings, public buildings and industrial buildings, especially in dry and hot areas. Applications in all types of buildings.

Background technique

China’s 2005 “Energy Efficiency Design Standards for Public Buildings” states that: China’s building energy consumption has exceeded one-fourth of the country’s total energy consumption, and will gradually increase to more than one-third as the people’s living standards improve. Among the building energy, the energy consumption of HVAC accounts for about 27.4%. Therefore, vigorously promoting HVAC energy conservation plays a vital role in building a resource-saving and environment-friendly low-carbon society.

The cooling load of the air-conditioning equipment in summer is mainly composed of the cold load of the air-conditioned room, the cold load and the fresh air load that need to be eliminated by the heat production of the unit itself. According to different regions, different meteorological conditions, different equipment conditions, and different envelope structures, the proportion of cold load occupied by the three parts is different, but the cold load formed by the heat of the air-conditioned room is the main weight part. Caused full attention. The total cooling load of the room consists of the following parts: 1. The amount of heat dissipation from personnel and indoor electrical equipment; 2. The cold load formed by the solar radiation of the window; 3. The wall, roof, etc. through heat conduction and convection The formed cold load; 4. The cold load formed by the outdoor fresh air infiltration through the doors and windows.

(1) Energy-saving analysis of windows and sunshade methods

According to relevant information, in the building envelope, the energy consumption of doors and windows is about 4 times that of the wall, 5 times of the roof, and 20 times of the ground, accounting for 40% to 50% of the total energy consumption of the building envelope. Therefore, enhancing the thermal insulation performance of doors and windows and reducing the energy consumption of doors and windows is an important part of improving the quality of indoor thermal environment and improving the energy-saving level of buildings.

For the indoor environment of the building, solar radiant heat is a very important external disturbance. In the envelope structure, the outer window has a significant influence on the air conditioning cooling load. Since the heat transfer coefficient of glass is much larger than that of non-transparent enclosures such as walls and roofs, the proportion of air-conditioning cooling load formed is much larger. According to statistics, the heat lost through the window accounts for 46% of the building energy consumption. The hot and cold load of the glass through the solar radiation accounts for about 20% to 30% of the air conditioning cooling load. Must be given full attention. According to the study, half of the cold load of global residential buildings and non-residential buildings is the heat load of solar radiation, and the solar radiation through the windows is the most important.

Therefore, the window is the weak link of building energy conservation, the black hole of building energy consumption, and the main direction to control building energy consumption. The solar radiation reaching the ground through the atmosphere includes direct radiation and scattered radiation, and the outer surface of the building envelope receives three scattered radiation from the air, namely sky-scattered radiation, ground-reflected radiation and atmospheric long-wave radiation. Normally (incident angle <60°), when sunlight is applied to the surface of ordinary glass, 7.3% of the energy is reflected and will not become The heat of the room; 79% directly into the room through the glass, all become the heat of the room; and 13.7% is absorbed by the glass, which increases the temperature of the glass. Of this absorbed energy, 4.9% will be transmitted to the room by long-wave heat radiation and convection, and the remaining 8.8% will also be radiated to the outside by long-wave heat radiation and convection, and will not become the heat of the room. Therefore, the higher the reflectivity of the glass, the lower the transmittance and the absorptivity, and the less heat the sun gets.

In order to effectively block solar radiation and reduce summer air conditioning load, the use of shading facilities is currently a common method. According to the location, it can be divided into external shading facilities, internal shading facilities, or between external shading facilities and internal shading facilities. The way to install the louvers between two layers of glass is called a double-layer leather curtain wall.

The infra-radiation heat that enters the room through the glass window is the solar radiation that is directly into the room through the window glass (referred to as the transmission of the solar radiation) and the window glass absorbs the solar radiation, and then transmits the heat in the room in the opposite direction and the radiation method (abbreviated as absorption and heat release). ) These two parts are composed.

The internal shading device can reflect part of the solar radiation, but a part of the outward reflection will be reflected back by the glass, so that the reflection is weakened. The inner sunshade only temporarily isolates the solar radiant heat from the inner sunshade, but the radiant heat is partially absorbed by the outdoor, most of which is absorbed by the sunshade and the glass, and then re-enters the room through radiation and convection, all of which become indoor heat. Did not fundamentally reduce the indoor air conditioning load;

The external shading facilities are better than the internal shading facilities. Because the external shading facilities are exposed to the harsh external environment all the year round, they have to withstand long-term sun and rain and variable wind loads, which are easily damaged and polluted in the external atmospheric environment. After reducing its ability to reflect the sun's rays, it is not easy to clean; affecting the shape of the building, not beautiful; some improper shading measures can not achieve effective insulation, but also bring more inconvenience to living.

The double-layered leather window wall combines the characteristics of the inner and outer sunshade. The louver is arranged between the two layers of glass. Although some disadvantages of the outer shading device are eliminated, the temperature of the louver heats up the glass interlayer due to the heat absorption. Part of the heat will be transmitted to the room to reduce its heat insulation capacity. At present, the technology is to adopt ventilation measures in the glass interlayer, and the heat of the glass layer is discharged to the outside through natural ventilation or mechanical ventilation, so that the sunshade can be insulated. The effect is closer to the external shading facility. The main disadvantage is that the thickness of the air layer between the two layers of glass is usually small, resulting in limited air flow and limited cooling effect. Secondly, the laminated louvers still have the problem of air pollution, and the cleaning after pollution is even more difficult than the external shading facilities. In addition, the overall production cost is high, and it is difficult to cooperate with the building. With different use time and different solar angles, the opening angle of the louver requires an electric adjustment mechanism, which increases the initial investment cost and the cost of maintenance.

(II) Energy-saving analysis of HVAC systems

The cold heat required by the HVAC system is generated by the heat source and the cold source, and the output of the cold or heat carrier is usually cold water or hot water. After the transmission and distribution system to the end of the air handler or system, the cooling capacity or Heat.

For the most used fan coil + fresh air conditioning system in construction projects, the wind system will ultimately transfer energy. Give the room to be adjusted to achieve the required room temperature and humidity parameters. Only the fan coil handles the indoor circulating wind, while the fresh air is the treated outdoor fresh air introduced by the air handler.

The fresh air required by the air conditioning system mainly has two purposes: one is to dilute the concentration of harmful gases in the room to meet the health requirements of the personnel, and the other is to supplement the indoor exhaust and maintain the indoor positive pressure. In recent years, with the improvement of people's living standards, the occurrence of sick building syndrome incidents in traditional air-conditioned closed rooms has caused serious consequences, which has caused people to pay attention to indoor air quality and their own health. There is an increasing trend in air conditioning fresh air volume in standards and specifications.

This creates some problems. First, the increase in fresh air volume will undoubtedly increase the building energy consumption, because the outdoor air temperature is higher than the indoor circulation wind. The second is the balance of room air volume. Even if the fresh air volume does not increase, a certain amount of fresh air is sent in. From the room air volume balance, the same amount of exhaust air must be discharged, otherwise the fresh air cannot be sent into the room normally. Therefore, for some fresh air systems that require functional air conditioning systems to have fresh air, or dry air evaporative cooling, how to remove fresh air entering the air-conditioned area?

There are usually the following situations:

1, no use to drain. If the fresh air volume is small, it can be discharged from the gap between the door and window by natural positive pressure.

2. The fresh air to be drained is collected and exchanged with the incoming air of the new fan for energy recovery. The pipeline is complicated, the investment is large, and the energy consumption is high.

The discharge mode of the above two conventional fresh air in the air-conditioned air-conditioned room, the first way, the energy of the fresh air is not recycled, there is a situation of low-grade energy waste, and the second way, due to the need to additionally increase the heat exchange equipment, There are many problems such as investment and building space coordination.

Therefore, from the control of the stable indoor air environment, to the building form and the envelope structure, the overall control must be required. The enclosure structure will achieve complete isolation between the interior and exterior of the building, whether it is natural lighting, air penetration or heat transfer. Thorough isolation between indoor and outdoor can effectively regulate the physical parameters of the indoors. Relatively speaking, the less energy consumption is required, the more energy-saving. However, starting from the improvement of the environment, we must first pursue natural lighting, natural ventilation, and even the heat transfer performance of the envelope structure. Some regions sometimes want the enclosure structure to become an "energy transmission channel" connecting indoors and outdoors. These two concepts will pursue completely different forms of architecture and form of enclosure.

In summary, windows are the weak link in building energy conservation, and the main factors causing the increase of indoor thermal and thermal load. However, it has not been seen that it can meet the needs of indoor air conditioning and can greatly reduce energy consumption and cost. Low methods and reports of their devices.
