Introduction of Water Source Heat Pump

Shallow water sources on the Earth's surface (usually within 1000 meters), such as groundwater, surface rivers, lakes, and oceans, absorb considerable radiation energy from the sun entering the Earth, and the temperature of the water sources is generally very stable. The working principle of water source heat pump technology is to transfer low-temperature thermal energy to high-temperature energy by inputting a small amount of high-grade energy (such as electricity). The water body serves as the heat source for winter heat pump heating and the cold source for summer air conditioning, that is, in the summer, the heat in the building is "taken out" and released into the water body. Due to the low temperature of the water source, it can efficiently carry away the heat to achieve the goal of cooling the indoor buildings in summer; In winter, heat energy is extracted from the water source through a water source heat pump unit and sent to the building for heating.

Water source heat pump is currently the refrigeration and heating method with the highest energy efficiency ratio (COP) in air conditioning systems, with theoretical calculations reaching 7 and actual operation ranging from 4 to 6.

The water temperature that can be utilized by the 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 temperature of the water body is 18-35 ℃, which is lower than the ambient air temperature. Therefore, the condensation temperature of refrigeration decreases, making the cooling effect better than that of air-cooled and cooling tower types, thereby improving the operating efficiency of the unit. The water source heat pump consumes 1kW. h of electricity, and users can obtain 4.3-5.0kW. h of heat or 5.4-6.2kW. h. of cooling capacity. Compared with air source heat pumps, their operating efficiency is 20-60% higher, and the operating cost is only 40-60% of that of ordinary central air conditioning.

Water source heat pump is a heating and air conditioning system that utilizes solar energy resources stored in Earth's water bodies as a heat source, and low-temperature water naturally dissipated from Earth's water bodies as a cold source for energy conversion. The water bodies that can be utilized include groundwater or rivers, rivers and lakes on the surface, and oceans. Surface soil and water bodies are not only a huge solar collector that collects 47% of solar radiation energy, more than 500 times the annual energy utilization of humans (underground water bodies indirectly receive solar radiation energy through soil), but also a huge dynamic energy balance system. Surface soil and water bodies naturally maintain a relative balance of energy reception and dissipation. This makes it possible to utilize the almost infinite amount of solar or ground energy stored within it. So, water source heat pump is a technology that utilizes clean and renewable energy.

Using surface water as a cold and heat source to release or absorb heat, without consuming water resources and causing pollution to it; Eliminating facilities such as boiler rooms, auxiliary coal yards, oil storage rooms, and cooling towers, the area of the computer room is significantly smaller than that of conventional air conditioning systems, saving building space and also conducive to the aesthetics of the building.

The water source heat pump unit eliminates the need for boiler room systems such as coal, gas, and oil during heating, eliminating combustion processes and avoiding pollution such as smoke exhaust and sewage discharge; The cooling tower is omitted during cooling, avoiding noise, mold pollution, and water consumption from the cooling tower. So, the water source heat pump unit operates without any pollution, combustion, smoke exhaust, waste residue, wastewater, exhaust gas, and smoke, and does not generate urban heat island effect. It is very environmentally friendly and is an ideal green and environmentally friendly product.

The water source heat pump system can provide heating, air conditioning, and domestic hot water. One unit can be used in multiple ways, and one system can replace the original two sets of boiler and air conditioning devices or systems. Especially for buildings with both heating and cooling requirements, water source heat pumps have obvious advantages. Not only does it save a lot of energy, but using a set of equipment can simultaneously meet the requirements of heating and cooling, reducing the initial investment of the equipment. 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 traditional air conditioning systems, and the installation period is shorter. It is also easy to change and install.

Water source heat pumps can be applied to buildings such as hotels, shopping malls, office buildings, schools, etc. Small water source heat pumps are more suitable for heating and cooling in villas and residential communities.

The temperature of the water body is relatively stable throughout the year, and its fluctuation range is much smaller than that of the air. The relatively constant temperature of the water body makes the operation of the heat pump unit more reliable and stable, and also ensures the efficiency and economy of the system; Adopting full computer control, with a high degree of automation. Due to the simple system, fewer unit components, and stable operation, the maintenance cost is low and the service life is long.
