Recently, a new type of energy home appliances - heat pump water heaters, air conditioners have attracted the attention of the majority of home appliance giants. Home appliance giants including Midea, Wanhe, Wanjiale, Wuxing, Tongyi, etc. have invested a lot of R&D and production costs in this field.
Not long ago, the draft national standard for "home and similar heat pump water heaters" led by the Guangdong New Energy Electric Professional Committee was also being formulated.
The biggest advantage is energy saving and environmental protection
Heat pump products are divided into three categories: water source, ground source and air source. Air source heat pump is widely used in domestic water heaters and household air conditioners. Water source and ground source heat pumps are mainly used in central air conditioning.
It is understood that heat pump hot home appliances are not using gas or electric heating like ordinary electric appliances, but a device that uses heat pump principle to extract heat from air, land and water to form heat energy to prepare hot water and hot air.
The biggest advantage of heat pump type appliances is energy saving, safety and environmental protection. It can use about 1 degree of electricity to get about 4 degrees of heat, and the water will not be charged, so users can be assured.
At present, the five-star heat pump water heater has been mass-produced; Tongyi's heat pump water heaters and air conditioners have been exported overseas; while Midea will use air source heat pump principle to produce air conditioners called "thermal cycle" air conditioners, which are said to have comprehensive energy efficiency. The ratio is as high as 8.3 and will be listed in August and September this year.
Water, ground source type central air conditioning domestic test water
Unlike air source heat pump products, which are mostly used in households, the principle of water source and ground source heat pump is mostly applied to the central air conditioning field.
According to a survey, traditional central air-conditioning is one of the major energy consumers, and energy waste and environmental pollution are prominent. Taking Chongqing and Shanghai as examples, central air-conditioning power consumption accounts for 23% and 31.1% of the city's total electricity consumption, respectively. Traditional gas and fuel-type air conditioners have large initial investment and high operating costs, and exist in both natural and residential environments. Threat.
The central air conditioner produced by the principle of water source and ground source heat pump is 30%~50% more energy efficient than the traditional central air conditioner, and can collect 47% of the solar energy, which is more than 500 times of the annual energy utilization of human beings. Therefore, it is used in some developed countries. used widely. At present, the domestic market has also begun to “test the water†of this type of central air-conditioning. At present, the Olympic sailing museum and the first domestic seawater power generation Qingdao power plant have started to use the air-conditioning system project, and have been designated by many Chinese real estate developers as high-end precision assembly sets. The product.
Experts in the industry pointed out that heat pump appliances, especially ground source and water source heat pump products, as a new type of energy home appliances, their technical standards are not perfect, but with the gradual "testing" of some giant-type enterprises, and will promote Chinese enterprises Rapid development in the general direction of environmental protection and energy conservation.
