So, how to use air source heat pumps correctly in winter? The following 8 actions will help you save thousands of dollars in a heating season~   1. Set the best temperature In winter, the indoor temperature should be adjusted to between 16℃-26℃, and the best temperature is around 20℃. If the indoor temperature is too hot, it will not only overload the air source heat pump, but also damage the compressor in severe cases, and it is not good for health. People who stay in high-temperature rooms for a long time will feel hot all over, and their eyes, ears, mouth and nose will feel dry; in addition, when the air source heat pump is heating, the air source heat pump can save more than 10% of electricity for every 2℃ lower temperature. 2. The temperature can be lowered appropriately at night At night, we sleep under the quilt, and we don’t need too high a temperature. Therefore, lowering the indoor temperature appropriately can not only save electricity, but also will not affect sleep. In the sleep mode of the air source heat pump, the working time of the air source heat pump compressor is relatively shortened, the downtime is relatively prolonged, and the intelligent temperature adjustment will naturally save more electricity.   3. Do not turn it on frequently Friends who have used air source heat pump underfloor heating know that each time the floor heating is turned on, the heating time is relatively long and the energy consumption is much greater than turning it on for 24 hours. Therefore, if no one is at home for a long time, the floor heating does not need to be turned off, and the water temperature can be adjusted to about 12℃.   4. Heating wind direction setting Some families use fan coil units at the end. The hot air has a light specific gravity. Using this physical common sense, let the air outlet go down when heating, and the hot air blows down. In this way, the hot air rises naturally, making the room warm as a whole, and the heating efficiency will be greatly improved, saving energy and reducing consumption.   5. Avoid large objects blocking The radiator radiates heat by radiation convection. The surrounding space is open for heat dissipation. Try to avoid placing large objects around the radiator, and try not to cover it. The distance between the radiator and the wall is between 3 cm and 5 cm.   6. Turn off rooms that do not require heating Some houses are large and have many rooms. When the population is relatively small, the heating can be turned off in rooms that are not occupied or are used less frequently. This can reduce the heating area, which not only saves energy, but also accelerates the heating temperature of the normally used space, killing two birds with one stone.   7. Pay attention to ventilation In a small space (about 10 square meters), the generally recognized optimal ventilation cycle is about two hours. Within two hours, if the ventilation can be done for about 15 minutes, the indoor air can be kept fresh and the power consumption will not increase too much, which is the most environmentally friendly and healthy.   8. Choose a highly energy-saving air source heat pump When purchasing an air source heat pump, you can choose some products with better energy saving performance, such as Leomon double first-level energy efficiency full DC inverter heat pump-Jingxiang A7 series air source heat pump, which can further reduce the consumption of electricity.   Final summary The above tips can allow you to enjoy warmth in the cold winter, while also saving electricity bills to a certain extent and extending the service life of the air source heat pump. In the face of a cold wave, correctly master the use of air source heat pumps to create a more comfortable temperature environment for yourself and your family.

If your air source heat pump is no longer functional, how much will it cost to replace it?   1. Brand and size A larger home or an air source heat pump from a well-known brand may drive up the cost. 2. Local climate Extreme weather may require a more powerful (and expensive) air source heat pump system.   3. Installation complexity If your ductwork is outdated, you may have to pay extra for repairs or upgrades.   4. Long-term savings While new air source heat pumps are expensive, improving the efficiency rating may lower your monthly bills.   5. Collect quotes Every home is different. Be sure to consult with at least two or three local contractors to make sure the price is right for you.

Cold Dew is coming, and the temperature drops sharply. Some cities in the north have started heating, and in the north, a considerable number of families have already used air source heat pumps. However, no matter how eager you are to turn on the air source heat pump, you must do a good job of inspection in advance.   The air source heat pump has stopped working for several consecutive months. If the heat pump is not well maintained, the system will inevitably have some minor problems. It is necessary to carry out relevant maintenance in time, which will greatly improve the energy-saving efficiency and service life of the heat pump and reduce the failure rate. Otherwise, it is easy to cause problems for winter heating. 1. Check whether the power switch and the wiring of the equipment are loose, and the wiring should be firm; whether the power cord and the controller signal line are aging or damaged, if so, please replace them in time.   2. When there are things blocking the air source heat pump, it is easy to affect the heat absorption and heat dissipation of the machine, thereby increasing power consumption. Therefore, the area around the air source heat pump should be kept clean and dry, with good ventilation. Do not pile up debris on the top cover and around the air source heat pump to keep the machine in good working condition.   3. Check the water system of the heat pump equipment, check whether the water valve switch position is correct, whether water needs to be replenished, whether the water pressure is normal, whether the air in the pipeline is drained, whether there are any leaks, etc. If there is a serious leak, you should contact a professional for repair in time.   4. The air source heat pump also needs to be cleaned regularly, otherwise the deposited dust and scale will not only reduce the thermal efficiency but also shorten the service life. In order to avoid affecting the heat pump, it is necessary to clean the outdoor unit heat exchanger (1-2 times a year) and condenser regularly. Use tap water and a soft brush to clean the surface of the external unit casing. Pay attention to the water pressure and direction, and do not let water flow into the external unit electronic control part. When cleaning, the soft brush needs to be brushed along the direction of the fins to avoid damaging the fins.   Final summary It is recommended that you keep the above maintenance methods for future use. Only by properly and reasonably maintaining the air source heat pump can you effectively extend the service life of the air source heat pump, reduce losses, ensure the safe operation of the air source heat pump, and be responsible for the health and safety of yourself and your family!

A common question is: Is it normal for heat pump noise when air source heat pump is defrosted?   If your air source heat pump makes a loud noise in cold weather, it may just be entering or exiting the defrost cycle - this is normal for winter conditions. In cold climates, the defrost cycle of an air source heat pump reverses the system to melt the frost. This can cause:   1. Valve shifting sound 2. Fan pause or rotation 3. Compressor restart   These changes can cause the air source heat pump to make noise temporarily, not malfunction.

In general, air source heat pump cooling consumes more electricity than heating. This is because the cooling process requires the transfer of heat energy from a low temperature environment (indoors) to a high temperature environment (outdoors), and this heat transfer process usually requires additional energy consumption.   In air source heat pump cooling, the working principle of the heat pump system is to recirculate the working fluid to achieve the purpose of heat exchange. The refrigerant absorbs indoor heat, then compresses it to increase the temperature, and finally releases the heat to the outdoor air. This process consumes electricity to drive the compressor and other auxiliary equipment, as well as to maintain the normal operation of the refrigerant in the cycle. In air source heat pump heating, the working principle of the heat pump system is to supply the indoor heat energy demand by absorbing heat from the outdoor air. Since the outdoor temperature is generally low and the heat required is low, the energy consumption in the heating process will be relatively low compared to the cooling process.   ​However, the specific energy consumption will also be affected by many factors, including climate conditions, indoor temperature, equipment performance and many other factors. Therefore, the energy consumption of air source heat pumps is different in different environments, and the energy efficiency should be evaluated and compared in combination with the specific equipment characteristics and application environment.
