Central air conditioning for most people understand, and air can also borrow the east wind of coal to electricity is well known, what is the difference between the two, the public perception of the two all correct? Most of the domestic air heat pump manufacturers are producing air water heaters, or production of air-source heat pump water heating equipment, most manufacturers and distributors believe that air-source heat pump products and central air-conditioning products are two completely different things, in the face of a shiny “golden bowl” in front of, we tend to just see it as a “copper rice bowl”. “Copper rice bowl”.
Air source heat pump and central air conditioning cognitive misunderstanding:
Some people think: air source heat pump is “heating”; central air conditioning is “cooling”. The two are different areas, different performance products.
In fact, the central air-conditioning products are also a kind of air source heat pump products, it is in the case of high temperature “handling” thermal energy, and the heat is emitted (thrown away); and the air heat pump products not only can be in the case of high temperature “handling” thermal energy, but also in winter Low temperatures in the case of “handling” heat energy, and the coolness emitted (thrown away). In other words, the central air conditioning is a low-performance heat pump products; air-source heat pump is a high-performance central air conditioning products.
Heat pump is “handling” heat energy tool, it is running, the heat end of the temperature in the lower, the exothermic end of the temperature in the higher. Heat pump “cooling” “heating” is in the evaporator and condenser ends at the same time: summer central air-conditioning indoor in the “cooling”, outdoor in the “heat production”; the heat pump is a high-performance central air-conditioning products, the heat pump is a “transport” thermal energy tool, it runs in the heat end of the temperature is reduced, the temperature of the heat release end is rising. Heating”; winter air source heat pump indoor ‘heating’, outdoor ‘cooling’. The pursuit of certain people to reduce the cost of developing simple heating heat pump products, which is an unrealistic idea, this product does not exist. Some people believe that: the principle of reverse Carnot cycle is the principle of heat pump heating; Carnot cycle is the principle of air-conditioning refrigeration principle. This is a misunderstanding of the working principle of heat pumps and air conditioners.
Some people think: air-source heat pumps in the cooling performance is far worse than the central air conditioning
Many people believe that: the main function of air-source heat pumps is heating, it is far worse than the central air conditioning performance in cooling. Therefore, many manufacturers are air-source heat pump products used in floor heating and hot water production, the other half of the air-source heat pump cooling function is ignored, due to the neglect of the professionals, making the user to the heat pump as an energy-saving boiler products, for which it is a central air conditioning and turn a blind eye.
In fact, air-source heat pump products evaporator area, evaporator heat transfer air volume, fin spacing are greater than the central air conditioning. Summer refrigeration evaporator into a condenser, condenser in the outdoors play a role in the dissemination of heat, therefore, it exudes heat performance is superior to the central air conditioning, that is to say, it is in the refrigeration performance is superior to the central air conditioning (the same type of air-cooled unit), of course, this conclusion applies to the ordinary heat pump compressor, except for the injection enthalpy, the second compression.
The actual operating conditions of the heat pump unit is also the case: if the air source heat pump in the winter -10 ℃ ambient temperature operation, then, the evaporator (heat-absorbing end) discharged at least -15 ℃ below the temperature of the cold air; condenser (exothermic end) discharged heat temperature in the 50 ℃ or more. And ordinary air conditioners in summer cooling discharged cold air temperature is only 7-12 ℃, the temperature of the exothermic end of the 35-45 ℃. Therefore, ordinary air-source heat pump products in the summer cooling, the performance is superior to the central air conditioning air-cooled units. Should be fully confident to enter the central air conditioning industry.
In fact, the “triple-supply” misunderstanding blocked the heat pump business line of sight!
Some manufacturers have launched a heating, cooling, hot water production triple-supply products, the purpose is to illustrate: air-source heat pumps, its wide range of uses, low cost of integrated installation, its main function is still in the heating, refrigeration is only one of its incidental 1/3 of the function. The “triple-supply” products in the actual installation, use, maintenance, there are many problems, it blocks our vision, so that we can not look at the central air conditioning industry.
Therefore, where the central air conditioning industry technology, heat pump companies can learn from, transplantation, use; where the central air conditioning industry dealers are heat pump industry dealers. So that the heat pump industry will have access to a large number of strong financial strength, experience, strong technical force of the central air conditioning industry dealers. Air-source heat pumps at the same time will be into the heating, hot water, central air conditioning industry. It will give the air source heat pump to bring significant development. Therefore, the central air conditioning heating and cooling field is an important market for the future development of the air source heat pump market.
