Commercial air heat pump water heater GB system to defrost of the air – heat – h
Heat Pump Network HC At 5 , the air can Heat Pump Water heater efficiency is relatively low, with 20% of energy consumption of cream and then run into financial can not afford to frost, that unit's life in danger, energy efficiency was also the greatly reduced. Indeed, the country introduced the subject of heat in the refrigeration and air conditioning Pump Equipment during the formulation of national standards for the most contentious is the differences of opinion during the discussion one of the largest standard so far is still in reasonable debate.
Air to heat pump water heater with air-conditioning heat pump are different, the two are not one thing, but very different, has the air to heat pump water heater business machine is the introduction of national standards that some nondescript, seems to be copying the air conditioning heat pump Chiller standard for pseudo-air heat pump water heater or a cottage covered with a cloak of legitimacy, you do this to interpretation.
Air heat pump water heater features and winter frost, is has been wrapped in the air can heat pump water heater technology a headache, do this through practice, testing and experiments in some shallow accumulated experience in this with you common share.
Current production air heat pump water heater has five categories a business specializing in air heat pump water heater manufacturers. 2, second: third-rate air conditioning manufacturers in transition. 3 Solar Energy Across to the manufacturers. 4 Home Appliances Class manufacturers. 5, and trade for OEM OEM manufacturers,. Country as a whole did not really do the efficacy of several low temperature, January 14, 2008 introduced the subject of commercial aircraft States, May 1 national standard implementation of commercial aircraft. Prior to making just a little more than a year, while the heat pump water heater products to enter the market but really only a short period of 5 years or even less than the national standard commercial machine is simply put the participating manufacturers invested 50,000 yuan to develop standards Hefei, the Committee to use standard functions of the cold rush release it, there is full participation of manufacturers Advertisement Operation suspect. Indeed, the State introduced the subject of refrigeration and air conditioning heat pump equipment in the domestic standard-setting process of the most contentious and also differences of opinion during the discussion one of the largest standard so far is still in reasonable debate.
Air to heat pump water heater according to national standard for working conditions, can be divided into two general types, and low temperature. Table of common thermal element that is the name of the air-side conditions of dry bulb temperature is 20 , wet bulb temperature of 15 , low-temperature thermal element that is the name of the air-side conditions of dry bulb temperature 7 , wet bulb temperature is 6 , 15 common type is the water, 55 water, water with low temperature is 9 , 55 water, from the standard point of view, to air heat pump water heater can be divided into two categories, one common type, Type II low temperature . This classification is not necessary. Currently the vast majority of manufacturers is common, that is pseudo-heat pump, cottage, and the development of a common type of standard, gave a low standard air heat pump water heater has an open door, so do not need technical efforts, as long as When the air conditioning heat pump water heater will be done on it, is to air heat pump water heater in the development and promotion of irresponsible, is central " Energy Saving "called blasphemy. We should learn from lessons of failure of other countries, knowing that is wrong, why go on?
Common type in the name condition dry bulb temperature 20 , wet bulb temperature of 15 above environments is quite possible. But the low-temperature conditions dry bulb temperature 7 , temperature and global temperature is 6 barely even when it is difficult to run, and low temperature conditions on behalf of dry-bulb temperature 7 , temperature bulb temperature 6 , low-temperature conditions of dry bulb temperature – 7 , temperature bulb temperature -8 , with variable loads common type 0 – 43 , low temperature -10 – 38 , short, common type of cold air to heat pump water heater is the low temperature conditions on behalf of workers conditions.
Standards such intention clearly established that the common type of air heat pump water heater in ambient temperatures below 5 to run is not enough. If the ambient temperature is below 5 to run, then select the low temperature of the air to heat pump water heater, then to the electric auxiliary heat into the national standard to create a high-sounding reasons, "if the application of common-type unit at low temperature down hard, serious consequences Even if the unit continuously, while the hot water produced by the temperature rise is difficult. "
Grounds under the national standard; air heat pump water heater is energy efficient from an overall sense, but with some adaptation, to adapt the scope of limited, if beyond the scope of the problems will emerge, so do not need technical efforts, as long as air-conditioning to improve click on the line, when necessary, use electric auxiliary heating, how much does not matter.
