Ground Source Heat Pump Technology And Its Advantages

by: zhonglv   Keywords: air, to, water, heat, pump

Ground Source air to water heat pump Is actually a very old technology, 40 years have applied, only the last five years related technology development, to rapid commercialization. Ground Source air to water heat pump manufacturer name first appeared in a 1912 Swiss patent literature, 20th century Europe 50 years the use of ground source air to water heat pump there the first climax. In the meantime, Ingersoll and Plass Kelvin line source according to the concept of proposed underground penstock Heat exchanger The line heat source theory, but when low energy prices, the system of high cost, have not been widely used. 70's, the oil crisis to people's attention to the energy-saving, cost-effective use of energy, so that the development of ground source air to water heat pump supplier into the climax stage, then the amount of underground buried pipes has been replaced by early plastic pipe. During this period the establishment of a number of European level heat exchanger of ground source air to water heat pump, but is mainly used for winter heating.

The early 80s, the United States, Canada carried out for the Ground Source air to water heat pump Heating and Cooling in the research work reported in the literature of many different types of ground source air to water heat pump manufacturer ground heat exchanger in the heat transfer process and the model, and run some projects summary and performance comparison.

 

U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (E PA ) Have confirmed that ground source air to water heat pump system is the most efficient, most environmentally friendly hot water, heating and cooling systems. On the one hand it underground soil or rock is relatively stable to heat and temperature Air conditioning System can maintain efficient operation throughout the year, for the ground source air to water heat pump supplier to save electricity 20-50% of users.

 

Calculated results from the literature can be seen, multi-zone against the wind system, single-zone against the wind system, cold water system and multi-zone variable air source air to water heat pump system is more efficient than were 1.54kw/ton, 1.40kw / tom, 1.23kw/ton and 0.88kw/ton, kw / ton, said power consumption kW / ton cooling capacity. Can be seen, compared with traditional air conditioning, ground source air to water heat pump manufacturer system is more efficient than the best.

 

The other hand, under the same conditions, using a ground source air to water heat pump system can reduce maintenance costs of buildings. Ground source heat pump is durable, its mechanical moving parts are missing, all the parts are not buried in the ground is installed in the room, avoiding the bad weather outside, it can be guaranteed for 50 years underground, above ground can be guaranteed for 30 years, Therefore, ground source air to water heat pump is maintenance-free air conditioning, saving maintenance costs, so that the user's investment can be recovered in about three years. Lincoln City and Nebraska on these two places and 20 schools had the air conditioning system maintenance cos air to water heat pump ts of the investigation. This 20 schools using 4 different cooling methods: ground source heat pump system (G HP ), With hot water Boiler Air cooler (ACC / GHWB), the water cooler with hot water boiler (WCC / GHWB), with steam boilers of the water cooler (WCC / GSB). .

 

In Atlanta on every family with an annual cost of air-cooled heat pump system is 826 U.S. dollars, the cost of the ordinary air-conditioning system 686 U.S. dollars, using ground source heat pump system costs 397 U.S. dollars. Visible, ground source heat pump system operating cost compared to other air conditioning system is very low.

 

More importantly, ground source heat pump system uses Refrigerants Injection in the factory was completely sealed, no leakage during use, the user need not fill any time refrigerant, thus reducing damage to the ozone layer. The system can be used for different structures, different area of residential buildings, it can be installed in new building construction can also be used for the transformation of old buildings, its design flexibility makes it a very attractive air-conditioning options. Ground Source Heat Pump dehumidifiers have particular strengths, which makes it very suitable for hot and humid summer weather, if the air distribution device with air conditioner, ground source heat pump characteristics at this point will become more prominent, so to to indoor air quality standards, ground source heat pump system is a very good option.

 

Ground source heat pump is that there are more advantages, government offices, apartments and restaurants. According to the U.S. A civil power companies could be Oklahoma State's user surveys in the Red River Valley: If you want to 10 points within 1 minute rate, 99% of the ground source heat pump users of its cooling capacity during the summer to play for more than 8 points , 73% of users hit out of 10 points.

Air Source Heat Pump Applications

by: zhonglv   Keywords: air, to, water, heat, pump

An overview of   In accordance with the “language of heating ventilation and air conditioning technology standard” (GB50155-92), air to water heat pump Is defined as the evaporator and condenser to achieve conversion of the cooler features. We can also called reverse Carnot cycleair to water heat pump manufacturer principle based on the work of both can be used to refrigeration, it can be used to heating units. Variety of air to water heat pump manufacturer classification, if the press with an air to water heat pump evaporator and condenser heat transfer medium in different categories, heat pumps can be divided into: air – air heat pump, air – water heat pump, water – water heat pump, water – air heat pump, soil – Air heat pump, and soil – water pump and so on. In which the air – water heat pump, that air-source air to water heat pump supplier water heater unit in engineering more widely used.

 

Heat pump research, production and application of seventies of the twentieth century began in the United States and other developed countries take the road of healthy development. China in Shanghai in 1980 to design and production of the first to R12 as working fluid, air compressor power 55KW? Water air to water heat pump, and put into practical engineering application. Has been the late eighties to the twentieth century, air to water heat pump manufacturer research, production and application in China have developed quickly. At first, application of heat pump works mainly to set the conditions for the boiler or no price premium is too expensive or non-chilling room of the building space available for only a few selected units imported brands, compare the form of a single unit, mostly for piston compression Integral air-cooled air to water heat pump units. Heat pump works in recent years, both in geographical or architectural features and scale in all the major breakthrough, the brand of air to water heat pump supplier units, type of options greatly expanded, both in many imported brands, and numerous Domestic brands have piston compression heat pump units, there are screw-type unit, with integral unit, but also modular air to water heat pump units, single-unit cooling capacity from 3RT-400RT, everything, and the unit’s cooling and heating performance, quality and reliability are improved significantly.

 

2, heat pump features Air source air to water heat pump has the following characteristics:

 

1, Air Conditioning System in one, and placed on the building roof, no need to set a special freezing room, boiler room, but also eliminates the need for chimneys and cooling building space occupied by water pipes.

 

Busy section of the city for the high cost of land building, or unconditionally set the boiler room building, air source air to water heat pump manufacturer is certainly a more appropriate choice.

 

2, no cooling water system, no cooling water system power consumption, no cooling water loss.

 

Air conditioning systems, such as using water-cooled chillers, evaporative water loss is not only the loss, leaching losses, as well as the sewage damage, water loss in winter frost, Xia Jiqi flush with the system when the loss, diluted loss chemical cleaning, etc., all The total loss of cooling water circulation of water about equal to 2? 5%, depending on the nature of chillers, cooling capacity equivalent to the loss of unit volume 2-4t/100RT? h. This is some of our serious lack of the city, is a relatively substantial amount. Moreover, a considerable part of the project under part load conditions remain the same volume of cooling water. Or according to the number of host operating units, only a few units for the corresponding adjustment. Our economy is relatively little previous attention to this.

 

3, since no boiler, no corresponding fuel supply system, no smoke, no cooling water system security, health, simple.

 

Road for warm professional, the boiler room with a possible security risk, In addition, the formation of the cooling water Legionella infections has been written, from the perspective of health and safety, air source air to water heat pump has a clear advantage.

 

4, less and focus on system equipment, operation, maintenance and management simple and convenient. Small systems can do the start-stop control by indoor fan coil air to water heat pump switches.

 

5, unit capacity from 3RT to 400RT, specifications, engineering adaptability, which will help refine classification system can be hierarchical, block, sub-systems, user element independent set.

 

6, summer, water-cooled unit is running lower than the COP value, more power, the winter run to save energy consumption. Nanjing this summer and cold winter for the city’s general building heat, the air to water heat pump manufacturer system of annual energy consumption of the boiler below the water-cooled unit plus air-conditioning system, but at current energy prices, the annual running costs of heat pump system than water cooling unit plus boiler program.

 

7, cost more. As a source of hot and cold air conditioning system’s investment in equipment, air source air to water heat pump costs higher than the boiler water-cooled unit plus cost of the program’s system integration cost 20? 30% have only a cold source such as equipment, air to water heat pump prices about water-cooled machine + boiler 1.5-1.7 times.

 

8, air source heat pump year-round exposure to the outdoors, operating conditions worse than the water-cooled chiller and its corresponding life expectancy shorter than that of water-cooled chiller.
