Every elderly person looks forward to a happy and fulfilling old age, which is also the deep concern of every family. However, as the younger generation runs around for careers and families, many elderly people choose to live in nursing homes to spend their old age in order not to cause trouble to their children.   The environment and facilities of the nursing home are key considerations for the elderly when choosing, especially the heating equipment in winter. A nursing home in Xingtai City, Hebei Province, has won the favor of the elderly with its excellent heating equipment. The management of the nursing home introduced 8 Leomon 60HP ultra-low temperature air source heat pumps to provide stable and comfortable heating for the nursing home, allowing the elderly to spend 2 cold winters warmly. 1. Constant temperature and energy saving, enjoy a comfortable life Xingtai's winter is very cold, with the lowest temperature reaching more than ten degrees below zero. For the elderly with weak constitution, this is undoubtedly a huge challenge. The introduction of air source heat pumps has completely changed this situation. According to the feedback from the director of the apartment, they used to rely mainly on burning boilers for heating, but this method is not only expensive but also not ideal.   Worse, burning boilers will also produce a lot of coal ash, which pollutes the environment.   But since the installation of the air source heat pump, these problems have been solved. The air source heat pump only needs a small amount of electricity to generate a large amount of heat energy, and the heating efficiency is as high as 400%, which is very energy-saving and efficient. And it uses ultra-low temperature EVI jet enthalpy increase technology, which can maintain stable heating even in an ultra-low temperature environment of -35℃.   In addition, the Leomon air source heat pump is also equipped with a remote intelligent control system. Users can set the temperature remotely through their mobile phones. The system can also monitor the indoor and outdoor temperature difference in real time, and adjust the indoor temperature in real time to keep the indoor temperature within the range of ±0.1℃. The director of the nursing home said: "The air source heat pump is really great! It is not only warm, but also very cost-effective!"   2. Low noise and quiet, enjoy a happy life The air source heat pump system is constant temperature and comfortable, not dry or dry. According to feedback from Mr. Li, a resident of the nursing home, after installing the air source heat pump, the room is warm all day long, not hot and cold, and many of his minor ailments have been alleviated. It is really full of happiness.   For the elderly, a quiet and comfortable environment is very important. The Leomon air source heat pump has very low operating noise, and almost no noise can be heard even when the machine is running. Mr. Li said: "Now my sleep has become better! There was always noise when the boiler was burning before, but now there is no sound at all, and I will no longer be unable to fall asleep due to the noise."   After two heating seasons of use, the air source heat pump has won unanimous praise from the elderly and staff of the apartment for its warmth, comfort, energy saving and quietness. With the progress of society and the increasing prominence of the aging problem, how to provide a better living environment and services for the elderly has become the focus of social attention.   Leomon undoubtedly provides a good solution to this problem, always protecting the elderly with warm and comfortable winter time, and upgrading the traditional "elderly care" experience to a pleasant "enjoy old age" time.

Air-source heat pumps have not yet been clearly defined. They are called high-temperature heat pumps because the outlet water temperature is higher than that of common air-source heat pumps.   The difference between high-temperature heat pumps and common air-source heat pumps 1. Different energy efficiency ratios High-temperature heat pumps require the outlet water temperature of the heat pump to be higher than that of conventional ones. As we all know, the higher the outlet water temperature of the heat pump, the more heat is required, but the thermal efficiency decreases. Conventional air-source heat pump water heaters, under certain working conditions, have a relatively high thermal efficiency of 3-5 when the outlet water temperature is 40°C; once the temperature reaches 50°C, the thermal efficiency becomes very low, below 3, and some are even less than 2. High-temperature heat pumps fully consider the issue of thermal efficiency at the beginning of their design. If heat pump technology cannot solve the problem of thermal efficiency; then, as an alternative new energy source, there is no advantage in energy saving. Therefore, it is necessary to select a working fluid with high thermal efficiency to fully reflect the high efficiency of heat pump products. Applying this working fluid, under rated working conditions, when the outlet water temperature is 40℃, the thermal efficiency is nearly 30% higher than that of common air source heat pumps; when the outlet water temperature is within 60℃, it is still very high, which is equivalent to the outlet water temperature of common air source heat pumps at 40℃. The outlet water temperature of high-temperature heat pumps can maintain a thermal efficiency of more than 3 at 85℃. Therefore, if high-temperature heat pump technology is applied to common domestic hot water needs, the thermal efficiency becomes very high, which is a standard that must be achieved and a benefit that consumers can enjoy. More energy-saving products mean spending less money to obtain better use value. 2. Different outlet water temperature For common air source heat pumps, the outlet water temperature can only be controlled within 60℃. Beyond this temperature range, the life of the heat pump will be greatly shortened, and the failure rate will become very high during operation, affecting normal production and life. When the outlet water temperature of the high-temperature heat pump is within 85℃, the heat pump is still very stable and the thermal efficiency is still so high. When the outlet water temperature is within 60℃, the high-temperature heat pump is more energy-efficient than the common air source heat pump; moreover, it can expand the use range of temperature and save energy at 60℃-85℃, thus becoming an indispensable alternative energy heat pump in future industrial production.   3. Operation stability The operation stability of the heat pump is closely related to the design selection and technical matching. For high-temperature heat pumps, various tests are first carried out according to the working fluid found. When various indicators can meet the requirements of high-temperature heat pumps, the required compressor type is selected according to the characteristics of this working fluid. Then we go to find professional compressor manufacturers and let them design and manufacture compressors according to our requirements to ensure that our design can be realized. In addition, the supporting products provided by various well-known suppliers are used to complete the integration of high-temperature heat pumps. Of course, the control system cannot be ignored. We have developed different control systems according to different products to fully ensure that the high-temperature heat pump is environmentally friendly, efficient and stable in use. From design to manufacturing, common air source heat pumps consider common requirements, so the selection of raw materials is different from that of high-temperature heat pumps: the raw materials of common air source heat pumps are configured according to common working conditions and cannot meet the requirements of high temperature and high pressure conditions. When the outlet water temperature requirement is relatively high, the failure rate of the system will increase greatly; high temperature heat pumps must choose high temperature and high pressure materials that can ensure the working conditions of high temperature heat pumps, which can fully meet the requirements of high temperature and high pressure.   4. Scope of application In addition to the field of normal temperature domestic hot water where common air source heat pumps work, high temperature heat pumps can also be reflected in industrial heat. There is a broad market in the preheating and waste heat recovery and reuse of industrial steam boilers, building heating, high-temperature drying and baking of food, and drying and baking of other industrial products. High temperature heat pumps are increasingly favored by large and medium-sized manufacturers in drying and drying.

The high temperature in the north is still continuing this year. We need a cooling artifact to make the heat "back off". Nowadays, more and more people choose air source heat pumps that are warm in winter and cool in summer, energy-saving and environmentally friendly, as a powerful assistant for health and comfort in all seasons.   However, while enjoying the coolness of summer, it is also very important to "deep clean" the air source heat pump system. Today, let's talk about why and how to clean the air source heat pump system when it is cooling in summer.   Why to clean the air source heat pump system During the long-term use of the air source heat pump, dust and dirt are easily accumulated in the filter, heat exchanger and other parts. These impurities will not only affect the heat exchange efficiency of the system, but also may cause system failures and even shorten the service life of the system. Therefore, regular cleaning of the air source heat pump system is of great significance to maintaining the normal operation of the system and improving the cooling effect. How to clean the air source heat pump system Preparation 1. Turn off the machine and cut off the power switch to ensure that the air source heat pump system is powered off. 2. Prepare neutral detergent, brush, spray pot, rag, and necessary disassembly tools.   Indoor unit (fan coil) cleaning 1. Use a screwdriver or other tool to unscrew the fan coil fixing screws or buckles, open the panel, and remove the filter on the fan coil.   2. Use neutral detergent to spray on the filter, let it stand for about 10 minutes, clean the dust on it, wipe the filter with a dry rag, dry it and put it back in place.   Outdoor unit cleaning 1. Clean the air source heat pump housing: Use a rag dipped in neutral detergent to wipe it to remove dirt and dust on the housing.   2. Clean the evaporator (fins): When cleaning the evaporator, first turn off the power, then spray the detergent on the evaporator and brush it clean, and rinse it from top to bottom with clean water.   3. Note: Do not flush water directly to the motor part to avoid damaging the circuit. In addition, avoid touching the fins directly with your hands when cleaning, because the fins may be very sharp and easy to cut your hands.   Precautions 1. Protective devices (such as goggles, protective gloves, protective masks, protective shoes, etc.) must be used during the cleaning process to prevent inhalation or contact with agents.   2. Deep cleaning of the air source heat pump system also includes: regular inspection and maintenance of the internal structure of the indoor and outdoor units, system accessories, annual use of descaling agents to clean the condenser, regular cleaning of the water filter installed outside the machine, etc., to ensure the good operation of the heat pump and extend its service life.   3. Deep cleaning involves machine pipes and other parts. It is recommended to contact after-sales professionals for processing.   Final summary Summer is here. Before enjoying the comfort and coolness of the air source heat pump, don't forget to give our air source heat pump system a comprehensive "bath". This will not only make the system run more efficiently and energy-saving, but also protect our health and safety. Take action quickly and start the summer high temperature rescue plan with Leomon!

There is a common fear of air source heat pump maintenance costs, but taking a proactive approach can keep expenses in check.   1. Schedule HVAC maintenance regularly so that minor problems are caught early This reduces the likelihood of major breakdowns and avoids added costs.   2. Keep filters clean Dirty filters tax the system more and cause more wear and tear. Replacing or cleaning filters is an easy way to reduce air source heat pump maintenance costs in the long run. 3. Maintain the outdoor area around your air source heat pump Clear away leaves, dust, or debris to ensure that air can flow freely. Obstructed airflow puts stress on the system and can result in costly air source heat pump repairs.   4. Consider a service contract Many HVAC companies offer programs that bundle inspections, minor repairs, and repair discounts. These programs can help you avoid skyrocketing air source heat pump maintenance costs by spreading the cost.   5. Compare quotes for major repairs If a major problem arises, ask for quotes from multiple sources, but avoid the cheapest option if it lacks reliable credentials. High-quality repairs are essential to protect your air source heat pump warranty and system performance. Sixth, keep records of every air source heat pump maintenance visit. This record proves that you followed HVAC maintenance guidelines, which is critical if you need to file a warranty claim.   Final summary Research energy incentives. Some utility companies or government programs provide subsidies for high-efficiency heating and cooling systems, including air source heat pumps. These incentives may partially cover the cost of upgrades or repairs, helping you control the maintenance costs of your air source heat pump. With these strategies, you will find that preventive maintenance can ultimately save you money by reducing the number of repairs, extending the life of the system, and maintaining optimal efficiency.
