Do you really save money with a heat pump? 1. Insulation is very important About the heating power consumption of air source heat pump , the first thing to consider is the insulation of the building, doors and Windows, height, wall insulation, etc., these are important factors that affect the heating cost of air source heat pump. The size and material of Windows and doors, glass is single layer or double layer, if the window is large, and is single layer glass, then the heat dissipation is relatively much higher, the corresponding need for more heat supplement, in the host selection, the value of heat load should be higher. The height is also an important factor that affects the heating cost of air source heat pump. The room is higher, the heat dissipation is greater. In addition, the orientation of the house, the temperature of the room, and so on, also affect the building's demand for heat.
2. host performance is the key Whether the air source heat pump heating equipment design is reasonable, how to choose the material, how is the process, these will also affect the heating cost of the air source heat pump. For example, regarding the defrosting problem of air source heat pump heating equipment, the defrosting logic and control of air source heat pump heating equipment are reasonable, and it is possible to achieve frosting, frost-free, and defrosting as much as possible. Unreasonable design of the heating equipment, the loss of the main engine during defrosting will be very large, it will not only affect the COP of the air source heat pump heating equipment, but also affect the indoor temperature fluctuations. Frost is related to several factors, with the air source heat pump heating equipment technical program, process production, process consistency has a great relationship. If the air source heat pump heating equipment defrosting logic is no problem, but the air source heat pump heating equipment is not done, the same problem will occur.
3. the host machine selection is correct air source heat pump heating equipment selection is appropriate, which is relatively easy to ignore a factor. For example, a large machine with a small room must cost a lot to heat, and a small machine that has been working for a long time in bad conditions may also cost a lot Project to do, however, host and air source heat pump heating condition completely coordination is impossible, that is 100 square meters with how much air source heat pump host is not accurate, can only within a certain range of heating to coordinate, how much is this range, there is no specific, we are doing with experience. 4.heating terminal selection is correct If there is no problem with the selection of the air source heat pump heating system, it cannot be said that the whole air source heat pump heating system is reasonable, because the air source heat pump heating system includes the main heating system and the heating terminal system. Heating end is floor heating, radiator or wind disk, heating energy consumption is very different, because different heating end of the water temperature requirements are not the same, the need for heat is naturally different. Generally speaking, the floor heating on the water temperature requirements of the lowest, generally around 35 ~ 40℃, small pipe diameter even with more than 20 degrees of water temperature can meet the indoor temperature standard; Disc heating followed, and the radiator heating relatively high water temperature requirements, especially the traditional cast iron radiator, general requirements of 60℃ or even higher. At such a high heating temperature, it is not appropriate to use an air source heat pump to work, and the energy efficiency is relatively low. In addition can not be ignored is the size of the air source heat pump pump, especially for a small house, the power consumption of the pump actually accounts for a very large proportion. Everybody on the market likes to choose model a little bit bigger when choosing water pump, because the water pump chooses small, water basically cannot reach heating terminal, indoor temperature is very uneven, comfortable degree is very poor, the customer can have an opinion. And the pump chose big, although energy consumption will increase, but at least can ensure the comfort of room temperature. As for the air source heat pump in the end choose big or choose small still need to choose according to the actual situation, between these two, the priority to avoid which risk, need to balance. If energy consumption is the priority, then the air source heat pump pump will choose small, if the priority to avoid indoor comfort, then the air source heat pump pump will choose large. Secondly, the pump velocity has less influence on the radiator and floor heating, while the wind disk has more influence. The location of the air source heat pump host is also important. First of all, it is necessary to ensure that the air source heat pump host inlet and exhaust air unobstructed, there is no obvious airflow short circuit between the exhaust air and the intake air. Secondly, the installation of air source heat pump main unit can not stick to the wall, maintain a reasonable distance, avoid being affected by dirty air flow, easy to clean the heat exchanger of the outdoor machine. 5.the user itself USES a habit to also possibly cause heating charge to be high Users said that their own air source heat pump heating costs high, many times ignored some of their own use factors. For a simple example, the indoor temperature is 21℃ and 24℃. There is a huge difference in energy consumption between the two. For every 1℃ increase in the room temperature, the energy consumption of the air source heat pump host increases by about 10%. Therefore, if the user wants to save more power, it is best to meet the needs of the temperature, the air source heat pump host water temperature lower. In addition, although we are in the installation of a good air source heat pump host, often tell the user not to frequently shut down boot, because the air source heat pump host frequently start, there will be a lot of energy consumption, so in use should try to avoid frequent switch machine. In addition, some users like to keep the Windows open for heating, because the indoor temperature is high when heating, and it will be stuffy, which will generate a lot of heat loss, resulting in a huge waste of energy. In general, on the one hand, to consider the external environment and unit performance, on the other hand, also want to develop a good and correct use habits, as long as pay more attention to, the energy saving effect of air source heat pump is very prominent.
