quality High Temperature Heat Pump & Co2 Heat Pump factory

Under the national policy, new energy air source heat pumps have been popularized at an astonishing speed and gradually become well-known! Many people only know that there is air source heat pump underfloor heating, but don’t know what advantages it has? In order to find the answer, the editor summarized the eight advantages:   1. Environmental protection and energy saving It saves about 30% energy compared to traditional heating products. The raw materials are all environmentally friendly and energy-saving products, and air source heat pumps are used to provide hot water circulation heating.   2. Simple and generous The design is simple and generous, easy to install. 3. Reliable quality Resistant to acid, alkali and salt corrosion, high pressure, high temperature, penetration, rust, and no scaling of pipes and pipes   4. Smooth connection and low friction.   5. Uniform heat dissipation The heat is evenly distributed on the ground, using the human body's temperature sensing characteristics, and the air flow is small.   6. Clean and healthy There is no dust in the room, and it can promote the balance of human blood, prevent and treat key inflammation and old cold legs, and improve self-immunity.   7. Long lifespan The lifespan is 3-5 years longer than that of common floor heating modules.   8. High sound insulation efficiency The floor heating module adds a thermal insulation layer, has a very good sound insulation effect, can reduce noise pollution, and there is no noise during the heating process, which is beneficial to the physical and mental health of the family.

The factory's staff dormitory is a large group. In winter, hot water and heating are important things, so many factories will carefully choose heat pumps. Now the most widely used are solar water heaters and air source heat pumps. 1. The factory is your own, you can choose solar water heaters + air source heat pumps. As long as there is sun, you can absorb the sun's heat energy to convert it into hot water for employees. Once it is rainy, the air source heat pump is turned on. The combination of solar water heaters + air source heat pumps is the best way to supply hot water. Although the initial investment will be more, this combination also has the highest return on investment. And the air source heat pump is a relatively energy-saving water heater.   2. For factory rental, there are two types: short rental period: less than five years, you can choose air source heat pump, which is more suitable; rental period: more than five years, you can choose air source heat pump + solar water heater, which is more suitable   3. If you don’t want to invest so much at the beginning, you can choose air source heat pump alone, because air source heat pump is more economical, so you should choose according to your actual situation.   Air source heat pump is a new type of environmentally friendly and energy-saving water heater. Leomon heat pump has been committed to the research and development and production of air source heat pumps for more than ten years, and has been highly recognized at home and abroad.

With the advancement and development of science and technology, people's pursuit of living standards is getting higher and higher. In the north, it is very cold in winter, so it is a very painful thing to take a bath in winter. Many large factories have a lot of employees, so it is more troublesome for them to take a bath, and the hot water supply is also very large, which will cause a lot of expenses for the factory. So can air source heat pumps provide hot water? In the past, many factories used electric boilers, coal/gas/oil boilers and other equipment to make hot water. However, these equipment not only have hidden dangers in safety and environmental protection, but most importantly, the heating cost is also very high. Mr. Li, a factory operator, told us, "We used natural gas boilers to make hot water in the past, but in recent years, with the continuous increase in national natural gas prices, coupled with equipment depreciation, management fees and other expenses, the cost of one ton of hot water is as high as 50 or 60 yuan. In order to save the cost of hot water, the factory can only provide hot water at regular intervals, but the workers will complain, and it is really difficult for us to do it. Later, air source heat pumps were introduced, which is really convenient. Hot water can be produced at any time, and the price is very affordable. We are now completely in love with air source heat pumps."   Leomon heat pumps have been committed to the research and development of air source heat pumps for many years. Its safety, environmental protection, energy saving and other characteristics have been unanimously welcomed and recognized by factory operators, and have become the preferred equipment for factory hot water.

When the cold air strikes, remember to take the following antifreeze protection measures for our air source heat pump. Do a good job of inspection to keep you comfortable and warm and extend the service life of the heat pump.   1. Ensure normal power supply In the cold season, in order to ensure the normal operation of the heat pump circuit, it must be guaranteed to be powered on normally. When the heat pump water path is unobstructed, as long as there is no power outage or power failure, the antifreeze function can be activated by plugging in the air source heat pump plug. Even if the heat pump is in the off state and not put into use, this function will automatically take effect. Otherwise, if the heat pump circuit is not powered on in cold weather, the antifreeze function of the equipment will fail to cause the equipment to freeze and will not be covered by warranty.   Some users have asked: Why is their heat pump still rotating when the outdoor unit is turned off? This is because when the ambient temperature is below 4℃, the air source heat pump will automatically start the antifreeze function. This phenomenon just verifies the statement that "as long as there is no power outage, the heat pump plug will have an antifreeze function, including when the heat pump is turned off." 2. Pay attention to pipe insulation Winter pipe insulation is very important for the operation quality of heat pumps. When the external ambient temperature is too low, the water temperature in the exposed pipes will drop rapidly. If insulation measures are not taken, the pipes will easily freeze and cause damage to the pipes. Therefore, standardizing pipe insulation measures is a necessary measure to ensure the stable operation of air source heat pumps in winter. In addition, if the pipes are frozen, do not use boiling water to melt the ice. Sudden heat is easy to explode. You should wrap the frozen part with a wet towel, and then slowly pour warm water to melt the ice, or use other heating equipment to bake and melt the ice.   3. Drain the water when the heat pump is not in use If the air source heat pump is not running in winter or needs to be shut down for a long time, such as: frequent power outages, heat pump shutdown at night, winter holidays, and winter heat pumps are not often used, the water in the heat pump, water pump, and outdoor pipes should be completely drained to prevent the heat pump from freezing, and the power supply should be cut off and the protective cover should be put on. When running again, please conduct a comprehensive inspection of the system before starting.   4. Notes on ice treatment When the main unit, water pump, pipes, etc. are frozen, do not use boiling water to melt the ice directly. Sudden heat can easily cause the copper pipe to burst. You can wrap the frozen part with a wet towel, and then slowly pour warm water to melt the ice, or use a heating device (such as heating tape) to dry and melt the ice. When the evaporator and the outside of the copper pipe are frozen, do not hit them with sharp objects. Use warm water to slowly inject to melt the ice.   5. Maintenance of the surrounding environment The air source heat pump needs to absorb heat from the low-temperature air. The more heat it absorbs from the air, the more energy-saving the air source heat pump is. The amount of heat absorbed is related to the surrounding environment of the heat pump. Therefore, ensure that the air around the heat pump is smooth. Regularly remove debris and snow around the air source heat pump, and ensure that the bottom drainage is unobstructed to avoid ice in the drain pipe blocking the drainage channel of the heat pump.   If the heat pump is affected by the surrounding environment, such as debris on the evaporator fins, etc., it is necessary to regularly maintain the heat pump and clean the stains on the heat pump. After maintenance, the heat pump will not only improve energy saving, but also reduce the failure rate.   Seek professional help The heating season is coming, and cold air will frequently visit. Users of air source heat pumps can refer to the above content to make corresponding specific inspections of the air source heat pump. At the same time, you can also call professional heat pump experts for help.

If your air source heat pump has some unusual phenomena, don't rush to report it. Because these phenomena may not be real faults, let's learn how to deal with them together.   1. The compressor does not start? If you find that the compressor is not running, it may not be that the machine is damaged. Check these two points:   1) Is the protection device activated? Under continuous power supply, the air source heat pump restarts immediately after shutdown, the fan runs normally, but the compressor does not run immediately. This is the compressor startup delay protection function, which avoids frequent compressor startup and protects the compressor. Just wait for about 3 minutes;   2) Sometimes it is because of compressor overheat protection. At this time, you need to find out the heat cause and restart the machine. Excessive water outlet temperature will also cause the compressor to not run. At this time, you need to reset the water temperature;   3) The default temperature difference of the heat pump startup is 5 degrees. The actual water temperature is 5 degrees lower than the set temperature before the compressor starts to work. Pay attention to check the set temperature and startup temperature difference;   4) The newly installed air source heat pump compressor does not start to work. You need to check the common end and linkage (if you do not use linkage, you need to short-circuit the common end). The heat pump does not start when it is turned on. The icon on the panel keeps flashing. This is the preheating protection function of the inverter household heat pump. It is powered on and maintained. It will start automatically after the preheating time is sufficient. 2. The air source heat pump makes noise from time to time? During the defrosting process of the air source heat pump, the four-way valve and the solenoid valve are switched. During the operation of the heat pump, the heat exchanger will make some noises when it expands and cools slightly, and when the refrigerant flows. Don't worry, this is a normal phenomenon.   3. The fan does not run? If the fan does not run, first check whether the fan blades are stuck by foreign objects, and then check whether the power cord of the fan is in poor contact, or whether the plug with the motherboard is loose. If so, plug the plug tightly. Finally, if the heat pump is in the defrosting process, the fan will not move, just wait until the defrosting is over.   4. Frosting of the heat exchanger? When running in winter, because the surface temperature of the heat exchanger is lower than the ambient temperature, and the surface temperature of the heat exchanger is lower than 0℃, the surface of the heat exchanger will frost, affecting the heat exchange effect, but it doesn't matter, the air source heat pump has an intelligent defrosting function, so the air source heat pump will defrost regularly.   5. The cooling and heating effects are not good? First, when it is found that the air source heat pump is not cooling or heating well or does not heat or cool, eliminate the following situations first:   1) Check whether there are foreign objects blocking the air inlet? It is possible that there are too many debris blocking the machine, which affects the air's ability to absorb heat from the air, resulting in a decrease in the operating efficiency of the air source heat pump. After cleaning the surrounding debris, the heating efficiency of the air source heat pump will immediately increase;   2) During the peak period of electricity consumption, the power supply voltage will be unstable, and it will not reach the normal voltage required for the operation of the heat pump. The compressor cannot work normally, and the refrigerant pressure is insufficient, which will cause the air source heat pump to not cool or have poor cooling effect. This phenomenon is more likely to occur when a large number of electrical appliances are running at the same time during high temperatures;   3) The heat pump has not been cleaned for a long time, such as a lot of dust adsorbed on the finned heat exchanger, and the air source heat pump has poor heat exchange effect when working, resulting in poor heating effect.   Get professional help Finally, remind everyone to clean and maintain the air source heat pump regularly and keep the heat pump well ventilated, which will help the normal operation of the air source heat pump and provide a cool and comfortable environment. If you have other questions or need more help, please feel free to contact the professional maintenance personnel of the heat pump.
