Heat Pump School: Why choose water source heat pump for heating?
As we all know, energy is the material basis for the existence and development of human society and the guarantee for human survival. The development of human society and energy utilization are inseparable. Water source heat pump heating is one of the frontier topics in the international air conditioning and refrigeration industry. It is the main form of renewable energy utilization such as solar energy and geothermal energy, and is also the most promising energy-saving and environmental protection device and system.
Working principle of water source heat pump
The shallow water source on the earth's surface absorbs the radiation energy from the sun entering the earth, and the temperature of these water sources is generally very stable. The working principle of the water source heat pump unit is to transfer the heat in the building to the water source in summer. Because the temperature of the water source is low, the heat can be carried away efficiently. In winter, the energy is extracted from the water source. The heat pump principle is to raise the temperature through air or water as a refrigerant and then send it to the building.
Generally, the water source heat pump consumes 1KW of energy, and users can get more than 4KW of heat or cooling capacity. Water source heat pump uses water as the heat source and cooling medium in both heating and cooling processes, that is, switching the working medium circuit to realize the operation of heating and cooling. As the medium of heat pump heating and cooling process, water can be used if the following two conditions are met: first, the temperature of water is between 7 ℃ and 30 ℃, and second, the amount of water should be sufficient. The source water can be various industrial waste water, domestic water, sea water, river water, etc., and even various industrial waste heat.
Remarkable advantages of water source heat pump heating
1. Significant environmental benefits
Water source heat pump is a heating and air-conditioning system that uses surface water as a cold and heat source for energy conversion. During heating, the boiler room systems such as coal, gas and natural oil are omitted, and there is no combustion process to avoid pollution such as smoke exhaust and sewage discharge; During cooling, the cooling tower is omitted, and the noise, mold pollution and water consumption of the cooling tower are avoided. Therefore, water source heat pump uses a technology of clean and renewable energy.
The available water temperature of the high-efficiency water source heat pump unit is 12~22 ℃ in winter, and the water temperature is higher than the ambient air temperature. Therefore, the evaporation temperature of the heat pump cycle is increased, and the energy efficiency ratio is also improved. In summer, the water temperature is 18~35 ℃, which is lower than the ambient air temperature. Therefore, the condensation temperature of refrigeration is reduced, which makes the cooling effect better than that of air cooling and cooling tower, and improves the unit efficiency. According to the estimation of EPA of the United States Environmental Protection Agency, a well designed and installed water source heat pump can save 30-40% of the operating costs of heating, cooling and air conditioning for users on average.
2. Energy saving
The electric energy used by water source heat pump is a kind of clean energy in itself, but when generating electricity, it consumes primary energy and causes emissions of pollutants and carbon dioxide greenhouse gases. Well designed water source heat pump unit can reduce power consumption by more than 30% compared with air source heat pump and 70% compared with electric heating. Therefore, while saving energy, water source heat pump also reduces and reduces the pollution emissions and greenhouse effect generated in the process of primary energy consumption during power generation.
3. Wide application range
It can be widely used in central heating and cooling of hotels, office buildings, schools, commercial villas, residential quarters, and other commercial and industrial buildings, as well as in swimming pools, dairy processing, beer brewing, cold rolling forging, cold storage, indoor planting, constant temperature breeding and other industries. One set of equipment can be used for cooling, heating and domestic hot water. For air conditioning systems, one heat pump provides two types of heat sources, which can save one-time investment. Its total investment is only 60% of that of traditional air conditioning systems, and it is easy to install. The installation workload is less than that of other air conditioning systems, and the installation period is short. It is also easy to change the installation.
The above is the principle and advantages of water source heat pump heating shared by Comfort100. Let's respond to the national energy policy of energy conservation and consumption reduction, promote the large-scale application of water source heat pump technology in China, and create a clean and beautiful urban environment for China.
