Abstract: Water ring heat pump air conditioning system is a kind of application of small water / air heat pump unit. That is, the water loop connects the small units in parallel to form a heat pump cooling and heating air-conditioning system which takes the waste heat inside the building as the main feature. This paper mainly analyzes the advantages and disadvantages of water ring heat pump air conditioning system.
Keywords: water ring heat pump heat pump air conditioning, water ring heat pump air conditioning system is a small water / air heat pump unit of an application. That is, the water loop connects the small units in parallel to form a heat pump cooling and heating air-conditioning system which takes the waste heat inside the building as the main feature.
Second, the system's advantages:
1, household settings, easy to use, flexible, fully realized household usage measurement.
2, when the building area within the area, and the inner area of ​​the internal load is large occasions, the use of the system is very beneficial.
3, in the building at the same time to achieve cooling, heating function.
4, no need to set up a separate room, less management staff.
Third, the deficiencies:
1, the cooling tower cooling need to be set, this time the system is basically similar to a water-cooled air conditioning system and deduct the energy consumption of cooling water system, the COP value (energy consumption ratio) depending on the manufacturers only between 2.6-3.2, Compared with screw chillers, there is no energy saving effect can be talk about, while substantially increasing the initial investment of equipment.
2, heating, if there is no waste heat within the building or when the heat is very small, the use of this system, it is bound to add a boiler. High-temperature boiler heat will heat the circulating water loop, into a low-temperature heat source (15-25 ℃). Then by the water / air heat pump unit consumes the energy will cycle low heat raised to high heat, to the indoor heating of this use is very unreasonable. It is pointless to use this system on this occasion, even more than the fan coil system.
3, high end equipment costs
4, if this system is used, outdoor cooling towers to be set, and the tower generated aerodynamic noise, the basic can not be eliminated, and the high cost. The screw machine mechanical friction noise easily overcome. In the middle of residential areas, it is clear that no one can ignore the noise pollution for many years. At the same time, the relevant government departments can not sit idly by.
5, the name of the great differences between the specifications of the brand equipment, can not be compatible, only for a brand of equipment, separate design of pipes and duct systems.
6, the compressor placed in the room, the noise is difficult to control.
7, due to the water system, the wind system is basically the same, on the host device alone. Prices are high on other forms of hosting.
To sum up: The system is not as publicity as energy-saving and convenient, but just a propaganda skills only, no value in this project.
