Air source heat pump purchase skills

Air source heat pump products can not only replace coal-burning stoves in rural areas for heating, but also replace urban thermal central heating. Generally, air source heat pump heating products can be divided into two types, household and commercial. Today, the editor mainly introduces household air source heat pump heating products.

　　Household air source heat pumps are generally suitable for ordinary heating users such as rural self-built houses, urban residential buildings (6+1, high-rise, small high-rise, etc.), villas, etc. According to the applicability of the environment, household air source heat pump products are divided into two types: air source heat pumps used in ordinary environments and ultra-low temperature air source heat pumps used in harsh environments (low northern temperatures). There are various terminal forms of household air source heat pump products, namely radiator, floor coil, and air plate. Users can freely choose according to the actual needs of the family. Moreover, household air source heat pump units are generally small and compact, and users can choose to hang on the wall or place the balcony. At present, some household air source heat pump heating units are also equipped with remote wire control systems, users can operate indoors without special care, no need to occupy the computer room, which greatly facilitates ordinary home users.

　　When purchasing a domestic air source heat pump, the number of horses is generally determined according to the actual needs of the family. Household air source heat pump heating products generally have a small number of horses, generally divided into 3, 4, and 5 horses. Users choose the number of horses to be heated, the heating terminal form, and building energy saving (behind the house wall, whether there is an insulation layer, etc.) , Environmental temperature (low temperature in the north) and other conditions, the specific selection of horsepower needs to be calculated and determined according to the actual situation of the user.

　　 When purchasing air source heat pump equipment, you need to pay attention to the following points:

　　1, product configuration

　　 Air source heat pump heating unit is mainly composed of three main components: evaporator (condenser), compressor, expansion valve, and a closed system composed of reversing valve, outer panel, fan, motor, liquid storage tank and other components. Generally speaking, the selection of accessories is a rigid index that constitutes the performance of the unit. When purchasing products, you must pay attention to the configuration of the product.

　　2. Energy efficiency conversion of the overall system operation (including energy saving)

No matter how high the configuration is combined, the z* high energy efficiency of the system may not be able to be used, so when purchasing products, you must pay attention to the overall operating energy efficiency of the product, and pay attention to the invention patents used by enterprises to improve product performance (invention patents are The unique core technology of the enterprise). Take Lipman's air source heat pump heating unit as an example. Under the premise of high configuration (Copeland Scroll compressor + Japan Ranko directional valve + Emerson expansion valve) + invention patent, the COP value of the product is also the energy efficiency conversion ratio. It is 4.37, and effective energy saving is 75%, which is at the leading level in the industry.

　　3, equipment stability

　　The stability of the unit operation is high, that is, the unit has been tested over time, the failure rate of the unit is low, and the operation performance is stable. Since the air source heat pump industry has only developed in China in recent years, companies that focus on the research and development of air source heat pump products have generally not been for a long time, so the performance of their own research and development products cannot be fully tested, plus the research and development of air source products Of enterprises are mainly concentrated in southern China, and the operating stability of units in the north is poor. Therefore, when purchasing equipment, the operating stability of the equipment must be considered.

　　 At present, the domestic air source heat pump market is highly regarded by users due to its unique advantages (energy saving, environmental protection, comfort, etc.). With the development of the heating market, the domestic air source heat pump market has a huge space.
