  • Air energy water heater does not heat? Maybe we need to add refrigerant
    In the air energy water heater, the refrigerant plays an important role in the transportation of heat, which is called the "blood" of the air energy water heater. When installing the air energy water heater, the installation personnel will generally add enough refrigerant at one time. If the installation is reliable, it will not be necessary to add refrigerant in 10 years. 如果说在使用过程中突然发现机组... Learn more > >
  • Hot water and air heating system installation
    In modern civil buildings, the way of air heating with hot water is more and more common. However, as far as the actual operation of the air energy hot water heating system is concerned, due to the low cognition of users for air energy heating, some engineering companies have just come into contact with such products. Therefore, in the process of product installation and use, some difficulties, faults and places needing attention are often encountered, and the places needing attention are not in place Learn more > >
  • What are the advantages of air source heat pump heating compared with wall mounted furnace heating?
    With the social attention to environmental protection, the governments of various countries have issued corresponding supporting policies to improve their natural environment. China is also the same, the government's more and more energy-saving policies, the production requirements of various enterprises are also higher and higher, so the air source heat pump industry is facing great challenges. In recent years, the air source heat pump and the ground source heat pump by the floor heating engineering business Learn more > >
  • How to maintain the air heater? In order to improve the service life
    As the fourth generation water heater after relay water heater, gas water heater and solar water heater, air energy water heater is loved by most consumers because of its advantages of environmental protection, safety and comfort.

  • Comparative analysis of air source and water source heat pump central air conditioning
    The central air conditioning system is divided into two categories according to the cooling (heat absorbing) medium: air source heat pump air conditioning system with air as medium and water source heat pump air conditioning system with water as medium. Both of them can meet the comfort requirements of human body in the place of use, but their structure and performance are different. Air source heat pump central air conditioning: This is the traditional way of central air conditioning Learn more > >
  • Air energy heat pump industry service and maintenance costs are "Crazy"
    For regular air water heater enterprises, in addition to hardware costs, in terms of software costs, the first is the cost of production and management. The normal cost is 3%. People need to manage, processes to be established, materials to be consumed, machines to be tested. Most of the regular air energy water heater manufacturers have to use ERP system. Shanzhai factories do not have these costs, and they are generally screw drivers processing plants. Press on Learn more > >
  • Heating cost calculation of ultra low temperature air source heat pump
    The ultra-low temperature air source water heater operates stably in the environment of - 25 ℃ ~ 43 ℃. It uses air as the heat source and has no pollutant discharge. It can produce 55 ℃ hot water to meet the demand of hot water between 35-55 ℃. It has heating function and is suitable for direct air supply or floor radiation heating. The operating cost of ultra-low temperature air source heat pump in winter and gas, electricity Learn more
  • Ingenious installation of air energy unit to improve engineering efficiency

  • Basic characteristics of Zhengxu special heat pump dryer
    The principle of Zhengxu special heat pump dryer is based on the inverse Carnot principle. The gas Freon is pressurized by the compressor and becomes a high temperature and high pressure gas (up to 100 ℃), which enters the heat exchanger (condenser) at the indoor side, and the refrigerant condenses and liquefies, releasing high-temperature heat to heat the air in the drying room. The material in the drying room vaporizes and evaporates the water in the material by the form of hot air Learn more
