Beauty of cold and heat source system is introduced
Central air conditioning heat and cold source has many forms, common water source heat pump, air source heat pump, gas boiler, bromide chiller t straight gas turbine, etc.;
Water source heat pump system in all kinds of cold and heat source, air source heat pump system (such as air-cooled hot and cold water unit) with the highest heating efficiency of heat pump technology, and the heating efficiency is much big JJloo %, water source heat pump system can effect comparing the coP in 4 to. So, does that mean water source heat pump system is the best way to heat and cold source? Of course, the answer is "no" can't simply c good and bad in system to determine what effect, the key is to see whether is suitable for construction needs, what the lowest form of less investment, operation cost and best effect. So, want to consider the location of the building situation of groundwater resources and whether there are other water, electricity price, the price of natural gas, etc., should also consider using different ways of investment.
For example, has a construction area of 2 delete m 'hotel, hotel, the location of the groundwater resources are very abundant, groundwater temperature for 13 y, direct use of groundwater refrigeration summer; Winter can use central heating, central heating heating fee is 205 / m z, a heating period heating fee of $40000. If heating with water source heat pump units, the operation cost of a heating period of about 3 delete nine heating equipment investment
About 100000 yuan, and takes up a 20 m 'room c in this case use central heating is better than using water source heat pump units. A year can save $1 mm on the surface, and can be installed t coffee oo yuan for water source heat pump units, used for other investment will get how much profit each year, less occupied - 20 m 'room, and quite inch: save the how much rent? So, the best way of heating is central heating.
Electric refrigeration l gas boiler system is one of the most common in the central air conditioning system, also is a kind of technology is very mature.
Water source heat pump system using water source heat pump units is developed on the basis of water chillers, its structure and working principle are basically identical with chiller, technology is mature, can effect comparing the coP is commonly 4. 5.
Wave process cooling in China's rapid development is at the end of the 20th century, this is mainly due to the various countries' scientists found that affect the earth's environment is an important problem is the destruction of the ozone layer, and freon is one of the main material of destruction of the ozone layer. Therefore, international health cattle organizations and governments have announced deadline to stop production, the use of freon. No freon, freon refrigeration system will lose the foundation of existence. User when choosing water chillers, for fear of using freon refrigerant water chiller will be washed out, even if the unknown today, after the production of refrigerant will be eliminated, then the chiller maintenance will be a problem, when the price of diesel is low, coupled with excessive publicity media on the evolution of his unit, makes possible the high speed development of his bromide refrigeration unit. Most users when choosing water chillers, first consider using his bromide chiller. But with oil prices rising and people's understanding and recognition of freon, the new research into alternative material success, the evolution of his direct-fired machine demand growth began to decline. But for the places where waste heat and waste steam is very suitable for using his bromide steam refrigeration units, such as: skin steam of the place such as power plants, smelters, Thomas Edison power plant with now is wedge bromide steam refrigeration unit. For natural gas supply, the price is lower region by using natural gas as fuel of direct-fired machine is feasible, and, of course, with the development of science and technology, absorption refrigeration technology is also in constant development.
