Let’s talk about the differences between air-cooled heat pump units and water-cooled heat pump units
I. Air-cooled units
Wind (air) is used for heat exchange to take away and absorb heat to produce cold water and hot water.
II. Water-cooled units
Cooling with water takes away heat to produce cold water.
III. Economic and Technical Comparison of Air-cooled Heat Pump Unit and Water-cooled Heat Pump Unit
The initial investment of air-cooled units is slightly higher than that of water-cooled units, and the unit refrigeration power consumption is slightly higher than that of water-cooled units. However, the annual comprehensive cost of air-cooled units is basically equal to or slightly lower than that of water-cooled units. The longer the annual running time of water chillers is, the more favorable it is for air-cooled units. The initial payback period of air-cooled units is shorter than that of water-cooled units. The amount of cooling water replenishment is an important factor affecting the cost of water-cooled units. Strengthening maintenance management and reducing water consumption are important aspects to reduce the cost of water-cooled units.
Characteristics of water-cooled heat pump unit
1. Wide application and low cost.
2. The most mature technology is also the most widely used air-conditioning system.
3. The cold and heat sources are generally centralized and easy to operate and maintain.
4. High refrigeration efficiency and energy efficiency ratio in summer.
5. Initial investment is relatively low, and the cost of material is greatly reduced in the water pipe system without thermal insulation.
6. The number of noise sources is lower than that of air-cooled units.
7. The requirement of the engine room is not high. It only needs to meet the general ventilation and ventilation requirements.
8. The service life of the unit is much longer than that of the air-cooled unit.
9. Relatively small in size and small in area.
