In recent years, with the continuous advancement of the “coal-to-electricity” project, the requirements for energy conservation, environmental protection, and safety in the heating industry have been improved, and air-energy heat pumps have also developed rapidly as a new type of environmental protection and energy-saving equipment. As a heating device, the air energy heat pump has won the attention and trust of users because of its zero pollution, low operating cost, flexible control and convenient installation. Air energy heat pump technology is extremely perfect and has been applied for many years. However, numerous users do not understand enough about current equipment such as air energy heat pumps, and need to pay extra attention to selection and use.
When using an air source heat pump for heating, you must pay attention to these four points!
1. The selection of air energy heat pumps should be careful.
Air energy heat pumps are developed from central air conditioning in water systems. After connecting to the heating system, it realizes an integrated system of central air conditioning and floor heating functions. The air-conditioning function of the air-energy heat pump is easy to understand, and it is not very different from the ordinary central air-conditioning, but it is more pleasant. Any type of air energy heat pump can achieve the function of central air conditioning. When heating in winter, due to the vast territory of our country, the ambient temperature in the north is considerably lower than that in the south, and the air energy heat pump can be divided into low temperature resistance. Broadly speaking, the air energy heat pump is normal temperature. Low temperature type and low temperature type, normal temperature type is mostly used in warm southern regions, and low temperature type and low temperature type are used in cold northern regions. Therefore, when choosing an air source heat pump host, attention should be paid to the usage scenarios. After all, the air energy heat pump used in the cold area includes full frequency conversion technology and jet enthalpy technology, which can achieve a normal heating environment at minus 25 °C, and maintain an energy efficiency ratio of more than 2.0 at minus 12 °C.
2. It is easy to power off when used in a low temperature environment.
There are two heat transfer media in an air source heat pump system, namely refrigerant (Freon or carbon dioxide) and water. The refrigerant is mainly circulated in the heat pump host, and the water is circulated in the indoor floor heating pipeline. It is precisely because the heat generated by the air-energy heat pump unit is transmitted through water as the medium. In a low-temperature environment, if the air-energy heat pump host is suddenly powered off and the power supply is not restored for a lengthy time, the water in the pipeline is easy to condense due to the low ambient temperature. Ice, in severe cases, the pipeline will expand and crack, causing the internal water channel of the heat pump host to rupture. If there is no one in the home for a prolonged time, the water in the system pipeline can be discharged, which can reduce the risk of freezing and cracking of the pipeline; if there is no one in the home for a short period of time, it is necessary to keep the heat pump host in the power-on state, so that the heating can be started by itself in a low temperature environment. Of course, if the air energy heat pump is used in the south with extreme temperature in winter, the power supply of the heat pump host can be cut off. No water will freeze after all, but descaling agents and antifreeze need to be added to the system to prevent damage to the pipes.
3. Don’t mess with the control panel
There are numerous buttons on the control panel of the air source heat pump main unit, including adjusting the water temperature, regular and setting other parameters. When the staff adjusts the parameters, do not press the buttons on the control panel at will, so as not to affect the operation of the heat pump host after pressing the wrong button.
Of course, the current air energy heat pump has added an intelligent system, and can also implement a “fool-style” operation. Through the explanation of the staff, it is only necessary to remember the buttons that the user needs to adjust. When the indoor temperature is not sufficient, the outlet water temperature can be slightly increased; when the indoor temperature is high, the outlet water temperature can be slightly lowered. For example, in winter, it is sunny for several consecutive days and the ambient temperature is relatively high, the user can set the outlet water temperature on the control panel to ℃ at night, and the ambient temperature is relatively low, the user can set the outlet water temperature on the control panel 40 degrees ℃ up and down.
The user does not need to operate the temperature control operation of the air energy heat pump on the control panel, but can also remotely start and close the air energy heat pump system anytime and anywhere through the connected intelligent system on the APP terminal, and the water temperature can also be controlled. The indoor temperature, also it can control the room independently, and finally provide users with simple and convenient operation.
4. No debris can be piled around the air source heat pump host
The energy saving of air energy heat pump comes from the application of jet enthalpy technology, which uses low power to obtain heat energy in the air, and then effectively converts it into the heat required in the room. During operation, the air energy heat pump absorbs heat from the air. After the evaporator is vaporized, it is compressed into elevated-pressure gas by the compressor, and then enters the cooler to be liquefied, and the absorbed heat is transferred to the circulating heating water to achieve the purpose of indoor heating.
If there are sundries around the air energy heat pump host, and the distance is relatively close, or plants grow around the heat pump host, the air around the heat pump host will not circulate or flow slowly, thus affecting the heat exchange effect of the heat pump host. When installing the heat pump host, reserve at least 80 cm of space around the host. There should be no obstructions within 2 meters opposite the fan of the side air heat pump host, and there should be no obstructions within 2 meters above the top air heat pump host. Try to keep the ventilation around the heat pump host as smooth as possible to obtain more low-temperature heat energy in the air for efficient conversion. Because when the heat pump host is working, the fins of the heat pump host can easily absorb dust, fluff and additional components, and the surrounding dead leaves, solid waste and additional debris can easily cover the heat exchange fins of the heat pump host. Therefore, after the heat pump host is used for a period of time, the fins of the heat pump host should be cleaned to improve the energy efficiency of the heat pump host.
The air-energy heat pump has elevated comfort, strong energy saving, elevated environmental protection, stable performance, long service life, wide application range, and multiple uses in one machine. After entering the heating market, it is extremely welcomed by users, and its share in the heating market is getting higher and higher. Of course, there are certain precautions in the selection and use of air energy heat pumps. Select the correct heat pump host model, operate the heat pump system properly in a low temperature environment, and operate according to the instructions or the staff’s guidance when setting and adjusting the control panel. There should be no obstacles around the heat pump host, making the air energy heat pump more efficient, more relaxed, and providing users with additional energy-saving services.
