Characteristics of air-cooled heat pump unit
1. Saving water resources, environmental protection and high utilization rate of equipment.
2. Installed outdoors, such as roofs, balconies, etc., without the need to build dedicated machine rooms, do not occupy the effective building area, save civil investment.
3. Cooling in summer and heating in winter save the boiler room, which is beneficial to engineering construction and landscape design.
4. The cooling water system and cooling tower, cooling water pump, pipe network and water treatment equipment are omitted, which saves the investment and operation cost.
5. Heating in winter saves electricity. Heat pump heating saves about two-thirds of the electricity compared with direct electricity heating.
6. Heat pumps come in many forms. Low noise heat pumps have relatively small impact on the surrounding environment.
7. Safety protection and automatic control are installed in one body at the same time. It runs reliably and is easy to install and use.
8. The longer the running time is, the more advantageous it is and the lower the maintenance cost is.
Selection of Unit Application
For the design of central air-conditioning system in large buildings, there is no fixed special mode, which needs to be considered in combination with the local objective conditions at that time. Whatever equipment form is adopted, it must cooperate actively with architecture, structure and other related electromechanical specialties. As a professional design, the most important thing is to combine the actual situation of the project, consider various factors comprehensively, satisfy the principle of optimum use and economy, and realize the wishes of investors on the premise of ensuring technical feasibility, safety and reliability.
Water-cooled units and air-cooled units have their own characteristics. They should be selected according to different use environment, space, refrigeration capacity of units needed, and different cities and regions. The larger the building is, the preference is given to water-cooled units. The smaller the building is, the better the air-cooled units are.
Air-cooler is mainly used in dry and water-scarce areas. Its advantages are that it saves room area, is easy to install. Compared with water-cooled units, its operating conditions are unstable under the influence of environmental temperature, while water-cooled units are mainly used in areas with relatively sufficient water sources. Its operation is stable. However, due to the problem of anti-freezing of cooling water, it is relatively hemp in winter. Trouble, because of the simple use of cooling towers, the north can not heat in winter, need to choose water or ground source heat pump system, refrigeration heating effect is better, is the best choice at present, air cooler in the North using heat pump heating has some difficulties, need electric auxiliary heating water device, in order to improve.
