Advantages of Weisheng Air Energy Heat Pump Dryer
What is the difference between an ultra-low temperature air source heat pump used in the north and a normal air source heat pump? Today, Weisheng environmental protection equipment is for everyone.
After the 13th Five-Year Plan, from the central government to the local government, it pays special attention to the control of environmental pollution, especially the concentrated expression of air pollution - the central government has designated the Tianjin-Guangdong air pollution transmission channel, directly subsidized by the central government. “2+26†cities to control smog pollution. From this point on, the north began the tide of coal-to-electricity and coal-to-clean energy. Due to the many advantages of air-source heat pumps, it became the main force of coal-to-electricity. Directly promoted the market development and product popularity of air source heat pumps.
Air source heat pump products were not known to many people two or three years ago, and a little bit of impression may be air-energy water heaters. For other products, there is no fog, no understanding, such as air heating and air conditioning integrated machine, air energy heat pump dryer and so on. That is to say, let alone the air source heat pump, after the promotion of the northern coal to electricity, know what is the air source heat pump, but what is the difference between the ultra-low temperature air source heat pump used in the north and the ordinary air source heat pump? Today, the Air Energy Network is a small editor for everyone.
First of all, the environmental conditions of the two operations are different. As we all know, the working principle of the air source heat pump is to convert the low heat energy from the air into the high heat energy available for use through the compressor, and then exchange with the refrigerant system to provide hot water, heating, cooling and drying (-12-85). Degree range) and other uses. The normal air source heat pump operates at a temperature below minus 10 degrees. If it is running at minus 10-25 degrees, it may appear.
The unit can not be defrosted: in frequent rain and snow weather and lower temperature, the defrosting capacity of the unit is weakened. Because the suction of the unit is too small, the density of air that can be inhaled is reduced. As time passes, the thickness of the layer is more and more high. Therefore, because the air conversion capacity is reduced, the circulation of the refrigerant is reduced, and the overall heating capacity is reduced.
The compressor is prone to failure: the exhaust gas temperature rises rapidly, and the working medium superheat is too high. When the working medium is overheated, the thermal conductivity of the working fluid in the condenser is drastically reduced, and the lubricating oil temperature rises, the viscosity decreases, and the influence The compressor is normally lubricated.
Second, the two technologies are different. Because of the difference in ambient temperature between the north and the south, the air market in the south is extensive, and the earliest products are air-energy water heaters, which are very popular in the south. Many air source heat pump manufacturers like Guangdong are doing air energy water heaters. With the rapid development of air energy technology, air energy heating quickly stabilizes the heel in the north. This is also the root cause of coal-to-electric air source heat pump in the north. Will be a breakthrough in 2016. The air energy technology here has the following main points:
1. Ultra-low temperature air energy operation technology, air source heat pump manufacturers have their own ultra-low temperature technology, and now most of the domestic ultra-low temperature operation technology of air energy manufacturers is imported from Germany. On this basis, the development of ultra-fast defrosting technology. Since the air energy heat pump main unit is generally installed outdoors, frosting may occur in frequent rain and snow. The air source heat pump main unit can intelligently judge the demand for defrosting, a very short defrosting time of 90 seconds, and this defrosting time is only one-sixth of the products of other industries.
2. Turbine direct injection and enthalpy technology, which is called jet blasting technology in the industry. Because the heating efficiency of the air source heat pump in extreme cold weather will be greatly attenuated, resulting in unsatisfactory heating effect. At this point, the ultra-low temperature air source heat pump needs to use the jet boosting technology to create a two suction port in the scroll, through the first The second suction circuit increases the refrigerant flow and the difference of the main circulating refrigerant, greatly improves the refrigerant circulation system, makes full use of the refrigerant flow and utilization rate in the compressor, and improves the stability and heating efficiency of the system. The ultra-low temperature air source heat pump is the first to break the dilemma that the air energy heat pump cannot operate efficiently in the north.
The above is the difference between the ultra-low temperature air source heat pump and the ordinary air source heat pump. I believe that you have a new understanding. According to senior experts, the coal-to-electricity market in Beijing alone is expected to exceed 8 billion yuan in 2018. The Ministry of Environmental Protection has divided the number of Beijing-Tianjin-Hebei air pollution transmission channels into 28 cities. It can be seen that the 2018 overall air energy industry is very popular. Advancing the coal-to-electricity policy and the development of ultra-low temperature air source heat pump technology, air source heat pump heating in the north is already unstoppable. However, the service scope of Weisheng air energy dryer has broken through a variety of materials in recent years, involving 10 major industries. .
