The snow-capped mountains and the glaciers of tens of thousands of years ago make you feel like stepping into the end of the world. Here is the "world's highest city" -- Pali Town, Yadong County, Shigatse City. The so-called "lonely at the top", the average altitude is more than 4,300 meters, so that people here with a lifetime of cold wind companion. Micoe, as a leading brand of air energy, has come forward to provide air heating services for pari Town primary school in Yadong County, Xigaze city, with excellent product performance and perfect after-sales service of its air energy units. It has set up another model project of clean heating in high altitude and extremely cold areas.
Leap into modern times, air can become a new way of heating the plateau
It is understood that Pagri Town (Pagri Zhen) is located in the middle of Yadong County, Xizang Province, known as the "world's first high city", about 4300 meters above sea level, is a cold and arid plateau climate area, although the sunshine time is long, but the annual minimum temperature as low as minus 20℃, winter as long as 6 months, even to June, there is no melting snow under the eaves. Under such harsh natural conditions, local residents still use relatively primitive wood and cow dung fire to keep warm. However, in the primitive classrooms, even basic fire heating is difficult to do, and young students can only "hard resistance", often shivering with cold, learning conditions are very difficult.
After the completion of the new school building, in order to create a warm campus environment for students and make the plateau no longer "cold and high", the school leaders decided to purchase a more advanced and efficient heating system for the school after consultation. After many investigations, Micoe's air energy heating scheme has been favored by the school.
Micoe comprehensive consideration of heating comfort, convenience, energy-saving effect and cost control and other factors, through detailed and thorough heat load calculation, the use of CSA system for Yadong County Pali Town primary school tailored air source heating solutions. The construction area of the comprehensive building of Pali Town Primary School in Yadong County is about 1460.08m ², and the heating area is about 909m². The building area is about 1978.32m ², and the heating area is about 1177m². Three ultra-low temperature and high efficiency air source heat pump units are used to run in parallel in the complex building and teaching building respectively (air-cooled heat pump unit and water pump room are located outdoors), and ground low temperature radiation heating is used in the indoor building. This scheme can fully meet the requirement that the heat produced by the air source equipment is still above 701KW in the low temperature environment of -12℃ outdoor environment in winter, and truly realize the function of safe and stable heating in the low temperature environment.
Installation service across the snowy plateau
In recent years, air source heat pump, widely used in the "coal to electricity" project in northern China, has provided a new idea for clean heating in Tibet. However, it is a very difficult challenge to carry out heating engineering transformation in plateau area. The climate of plateau and high altitude area is complex and changeable, easy to hypoxia, low temperature, strong ultraviolet ray, heavy sand, etc., which greatly increases the difficulty and quantity of project construction.
"Pali Town Primary School is located in a remote area. It takes one week for air energy products to travel from Shunde, Guangdong province to Lhasa, Tibet via Sichuan-Tibet Line, and it takes eight hours to drive from Lhasa to Pali Town. In winter, the temperature is as low as minus 10℃ ~ 20℃, which makes it difficult for many people to adapt and easy to lack of oxygen. Micoe Took part in the central heating project renovation of Pari Town Primary School.

Heating Pari Town primary school, he recalls, was first a matter of unit transport. In March 2022, Micoe Pali Town Primary School clean heating project came into the construction, the road condition was particularly bad, the car is prone to break down on the way. As the altitude continues to rise, altitude sickness and road closures caused by heavy snow occur one after another, and mobile phone signal is poor. Living in a sparsely populated Tibetan area, I have to find my own way to solve the problem. For example, in some places the carts could not reach, so they were transported separately by small cars.
Customized solutions, Micoe warms every hand
In addition, the installation process is extremely difficult. Because the unstable voltage of the school is easy to power off during the construction process, the installation team must prepare a diesel generator in advance. Once the power is off, it can continue to work by itself. Due to the lack of oxygen in the plateau, the working intensity can not be too high, and the labor efficiency is lower than that in the plain area. March to April, just belongs to the dry and windy season, sand and long duration, put forward a severe test to the construction. Under the environment of minus 10℃ or so, if the construction only wears a layer of gloves, it is easy to be frozen by hot-dip galvanized steel pipe, and sometimes remove the skin of the hands. Only two or three layers of gloves can work, greatly reducing the sensitivity of the fingers.
Despite the difficulties, Micoe managed to complete the project smoothly. In the scoring standard of the central heating project of Pari Town Primary School, Micoe got high marks in both the perfection and implementability of the transportation guarantee scheme and the completion of the detailed work schedule of the supplier, and was unanimously recognized by the project party and leaders.

Air source heat pump water heater units and solar water heaters, as necessities of residents' lives, are both devices that use natural and environmentally friendly energy to generate hot water, but they have essential differences. The air source heat pump water heater unit uses air heat as its energy source, but the way it obtains energy is active, so it is not affected by cloudy, rainy, days and nights. The way solar water heaters obtain energy is passive. It relies on direct sunlight to have a better effect, so it can only produce hot water on sunny days.
Here is the content list:
What kind of device is an air source heat pump hot water (heater) unit?
What is the working principle of the air source heat pump hot water (heater) unit?
Air source heat pump hot water (heater) unit needs electricity, will the operating cost be high?
This equipment of air source heat pump water is high-tech energy-saving equipment for the production of hot water. It absorbs heat from the air to heat water to 65°C (low-end manufacturers heat it to 55°C). As central hot water equipment, drawing on the principle of an all-in-one heat pump, it is widely used in collective water supply units such as hotels, sauna centers, hospitals, factories, and residential communities, as well as small water supply units such as villas, residences and beauty salons.
The air source heat pump hot water (heater) unit consists of a compressor-condenser-throttle-evaporator-compression mechanism into a circulating system. The heat medium (also called refrigerant) circulates in the system under the action of the heat pump. The air source heat pump completes the gaseous pressure increase and temperature rise process in the compressor (the temperature is as high as 80-100 ℃). After it enters the condenser, it releases high-temperature heat to heat the water, and at the same time, it is cooled and transformed into a liquid state. When it runs to the evaporator, The liquid quickly absorbs heat and evaporates and transforms into a gaseous state again, and at the same time the temperature drops to minus 20 ℃-30 ℃, then the air around the evaporator will continuously transfer low-temperature heat to the heat medium. The continuous circulation of the heat medium realizes the process of converting the low-temperature heat in the air into high-temperature heat and heating the cold water.
The air source heat pump water heater (heater) unit is different from an electric water heater (heater) unit. The electric water heater (heater) unit uses the electric heating tube to directly convert electrical energy into heat to heat cold water. The highest conversion efficiency of electricity to heat is about 95℅. However, the electric energy consumed by the air source heat pump water heater (heater) unit drives the air source heat pump to work and only plays a role in promoting the circulation of the heat medium. Because a large amount of heat in the air enters the system, the energy obtained by the hot water is much greater than that consumed by the heat pump. For electric energy, the ratio of these two energies can reach more than 3-4 times, that is, the conversion rate of electricity to heat is as high as 400℅. That is to say: the main energy for heating water in the air-source heat pump water heater (heater) unit system is the surrounding air, and enough electricity can be obtained by using 1/3 or 1/4 of the electricity consumed by the electric water heater (heater) unit. For hot water, the operating cost is obviously much lower than that of electric water heaters or electric boilers.
It is the responsibility of each manufacturer to produce an air source heat pump that meets the standards, so as to ensure the safety of the electricity supply. MICOE conducts many tests on durable air source heat pumps before they leave the factory, and the quality qualification rate is guaranteed. If you are in the air source heat pump business, you can consider our cost-effective products.
The heat pump is a high-efficiency energy-saving device that makes full use of low-grade heat energy. A swimming pool heat pump is an important application.
Here is the content list:
1. What are the performance characteristics of swimming pool heat pumps?
2. What are the classifications of swimming pool heat pumps?
1.The recovered heat is used to heat the swimming pool air or pool water through the regeneration system to ensure that the indoor air is at a constant temperature. The condensed
water produced by de-temperature can be directly discharged outdoors or recycled into the swimming pool to supplement the pool water.
2. Considering the operating cost of the swimming pool heat pump unit, a large amount of outdoor fresh air with low humidity can be used to adjust the humidity of the indoor air in spring and autumn to reduce the operating cost of the swimming pool heat pump.
1. In the process of promotion to the urban market in recent years, the swimming pool heat pump, which is mainly targeted at middle and high-end consumer groups, has stood out from the encirclement of solar energy, gas boilers, and coal-fired boilers. With its advantages of safety, energy-saving, and convenient operation The dark horse's posture occupies the high ground of the transition to "low carbon and energy-saving". His working principle is to absorb low-temperature heat energy in the air and convert it into high-temperature heat energy after being compressed by a compressor to heat the water temperature. The initial investment of a swimming pool heat pump is three to five times that of gas, natural gas, and electric water heaters, but its daily operating costs are lower. Therefore, swimming pool heat pumps will surely become the leading products in the hot water market in the future.
2. Swimming pool heat pumps can be divided into air source swimming pool heat pumps; water source swimming pool heat pumps; soil ground source swimming pool heat pumps;
According to the purpose of the swimming pool heat pump system, it can be divided into independent swimming pool heat pump hot water system; swimming pool hot water and air-conditioning combined swimming pool heat pump system;
The swimming pool heat pump technology adopts the principle of reversed Carnot cycle. Under the promotion of high potential energy, heat flows from a low heat source to a high heat source, which means that the heat source that cannot be directly used is converted into a usable high-grade heat source, so as to achieve partial savings. One-time high-level energy technology.
It is the responsibility of each manufacturer to produce a swimming pool heat pump that meets the standards to ensure the healthy development of the swimming pool heat pump market. MICOE conducts a large number of quality inspections on the swimming pool heat pump before leaving the factory, and the quality assurance rate is guaranteed. If you are engaged in the swimming pool heat pump business, you can consider using our cost-effective products.
