The concept and working principle of low temperature and special gas 1 water source heat pump technology Water source heat pump technology is the use of low-level thermal energy resources formed by shallow surface water on the earth's surface, such as geothermal water and underground water, as well as lakes and geothermal energy absorbed by lakes. Using the principle of heat pump, a small amount of high-level electric energy input is used to realize the low-level thermal energy to high-level thermal energy. The shallow water source on the earth's surface, such as the groundwater and the rivers, lakes, and oceans with depths of 10001 and 1, absorbs the sun and enters the earth. The phase's radiant energy 1. And the temperature of the water source is very stable. The principle of the water source heat pump unit is to transfer the heat in the building to the water source in the summer. Because the water source temperature is low, the heat can be removed efficiently, and in winter, it is from the water source. The medium extraction can be sent to the building after the temperature is raised by using medium gas or water as a coolant in accordance with heat pump looseness. Di often water source heat pump consumes 1 energy, the user can get more than 41 calories or cold.
Compared with the heating system of boiler electric fuel and air source heat pump, the water source heat has the advantage of helium. The heating boiler mouth can convert 9 to 98 electric energy or 7 calories of 9 peppers into fuel for the household. Flash source heat source saves more than 23 kilowatts of electricity than electric boiler heating and saves more than 12 kilowatts of energy than fuel boilers. Since the heat source temperature of the water source heat pump is relatively stable throughout the year, it is generally 1025, and its cooling and heating coefficient can reach 3.54.4. Compared with the traditional air source heat pump, it is about 40 or so higher, and its operating cost is 506 of an ordinary central air conditioner. Therefore, nearly 10 years, especially in recent years, the water-source heat pump system has been rapidly developed in North America such as Midea Canada, Central Europe and Northern Europe, Sweden, Sweden, and other countries. The water-source heat pump market in China is also increasingly active and can be counted. This technology will become the most effective heating and cooling technology in the 21st century. 2 Water source heat pump features Water source heat pump technology uses ground water as a cooling and heating source for air conditioning units, so it has the following advantages.
2.1 Renewable Energy Utilization Technology Water source heat pump is a water resource that can be used in the heating and air-conditioning system that can benefit from the use of solar energy resources stored by thieves in the Earth’s water body as a source of heat and cold, including groundwater or some rivers and lakes in river areas. The marine soil and water body is not only a huge solar collector, but also collects 4 views of solar radiant energy, which is more than 500 times of the annual use of human energy. Underground water receives solar radiation energy indirectly through the soil. The dynamics of the giant can balance the system. The soils and waters of the land naturally maintain a relatively balanced acceptance and divergence. This makes Lee, Received the date of 2001 Yeye 718 water source heat pump system's outline analysis 郛 Zhijun, Wang Min Dalian Bingshan Group Co., Ltd., Dalian, Liaoning 6033 technology is the use of renewable energy technology rice detailed description of the characteristics of water source heat pump system And there are some problems in the promotion and application of cold, hot and cold systems making it possible to use almost unlimited solar energy stored therein. So, water source heat pumps use clean renewable energy sources 22 Energy efficient water source heat pump units have good water body Winter is 12 22, water body temperature is higher than ambient air temperature, so the heat pump cycle 35. Water body temperature is lower than the ambient temperature, so the cooling condensation temperature is reduced, so that the private cooling effect is better than the air-cooled and cooling economy, the unit efficiency is improved. 23 Operation stable and reliable The temperature of water body is relatively stable, its fluctuation range is far less than the change of air, it is a very good source of heat and air conditioning, and the characteristics of constant water temperature make the heat pump unit more reliable and stable. Ensures the high efficiency and economy of the system There are no difficulties in winter defrosting of air source heat pumps, etc. The power consumption of a good water source heat pump unit is equivalent to that of the air source heat pump, which is equivalent to reducing the refrigerant used in the water source heat pump technology of more than 7 tender. It can be 622 or the operation of the water heating unit without any pollution, and it can be built in the residents. , No broil, no smoke, no exhaust, no need to store fuel waste, no long-distance transport of heat, more than 25 machines, a wide range of applications, water source heat pump system can heat air conditioning also available for domestic hot water.
Multi-purpose machine. The system replaces the original two sets of boilers and air conditioners or systems, especially for buildings where heating and cooling are required at the same time. The small water source heat pump is more suitable for the heating and air-conditioning 26 of the villas. Because of the stable working conditions of the heat pump unit, a simple system can be designed with fewer parts, the unit operation is simple and reliable, and the maintenance cost is low. The high degree of automatic control can be achieved with long service life. Of course, everything has its two sides, and the water source heat pump also has it. The water source conditions used by the 7-foot source heat pump can theoretically use cut water resources, but in actual projects, the cost difference of different water resources utilization is quite large, so whether there is a suitable water source in a non-areas area becomes a water source heat pump The key to the application is that in the current water-source heat pump utilization mode, the closed-system cost is relatively high, and for the open-system, the 7-foot source requirement must satisfy the fixed temperature water quantity and cleanliness for the use of the underground pumping and recharging. The geological structure of the site must be taken into account. Ensure that wells can be found in economically conditional wells. Also consider the geological and soil conditions of the land to ensure that recharge of tail water can be achieved due to the different users and national energy policy fuel prices in different regions. The impact of the basic conditions of the water source, sub-investment and operating costs will vary with the user's different, although overall, the water source heat pump operating efficiency is relatively low cost, but with the traditional air-conditioning cooling heating method In contrast, under the different requirements of different regions, the investment economy of the 7-foot source heat pump will be very high. 3 Currently, there are water exploration and extraction technologies in China's water source heat pump applications, and the cost of sweat extraction should reduce groundwater irrigation. The technology should be considered in connection with local conditions. The design of the water source heat pump system for the irrigation system should consider the cooperation of the entire system. Water source heat pump unit is a green product with great potential for development. The advantages of human beings are high-efficiency, energy-saving and economical, and the use of maintenance and installation is very simple. However, the promotion and application of water source heat pump requires more people in all fields of various professions to work together to cooperate and design and manufacture the system from the government policy. All parties involved in the management, such as management, had to share the misfortune and make the water source heat pump widely used by users.
