The low-temperature river water/tap water/lake water (≥1℃) source heat pump unit uses underground shallow geothermal energy such as groundwater, soil, Yellow River water, lake water, etc. as the main energy source, and the driving energy as auxiliary energy. Through the advanced low-temperature water source heat pump air-conditioning system, it will take The development and utilization of the inexhaustible geothermal energy resources that remain within the low temperature range all year round make them available high-grade thermal energy to meet the needs of buildings for cooling in summer and heating in winter. The use of the unit is not affected by the environment and climate, and its operation is stable. It is a new type of heat pump air conditioning system that uses renewable resources, is efficient, energy-saving, healthy and pollution-free.

With water from the Yellow River and Weihe River (water temperature >1°C) as the cold and heat source of the system, water resources are very abundant. In winter, it is difficult for water to freeze when it flows, or it may be carried away as soon as it freezes into a mixture of ice and water (the ice-water mixture contains fine ice chips, and when flowing, the ice chips do not have enough time to form stable adhesion, making it difficult to freeze). When water forms fine ice chips, it releases a large amount of latent heat of vaporization (the latent heat of solidification of water under standard atmospheric pressure is 79.6kcal/kg, and the latent heat of vaporization is 538.8kcal/kg). The low-temperature water source heat pump unit can extract river water from ≥1℃ to an ice-water mixture of 0℃, and perform phase conversion heat extraction to extract heat. The heat exchange amount is large, and the heat exchange efficiency of the unit is high. The river water temperature is 0℃, and the hot water outlet temperature is 40°C. The unit energy efficiency COP can reach 3.98.

 

Container-type structural design, high pressure-bearing strength, and the exterior is decorated with reinforced color steel plates. The appearance is beautiful, and the steel plate is treated with multiple anti-corrosion spray paints. The box body is made of 10 cm sound-absorbing rock wool, sound insulation and thermal insulation cotton, which has good thermal insulation performance and small cooling loss.

 

Low-temperature water source heat pump units are favored by the market for their reliability, stability, energy saving and environmental protection. It can be widely used in hotels, hospitals, office buildings, cinemas, gymnasiums, commercial buildings, industrial and mining enterprises and other places with river/lake/wastewater around the building to provide hot (cold) water for the air-conditioning system. The unit can also recover the condensation waste heat of the refrigeration operation. Economically produce sanitary hot water and improve the quality of human life.
