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.

This project adopts Micoe air source heat pump pressure system to solve the traditional non-pressure commercial solar hot water and heating system serious heat waste, poor hygiene grade, high maintenance cost, hot water sometimes hot and sometimes cold, winter heating and other problems.
3 System Advantages
Micoe air source heat pump pressure system all uses modular pressure enamel heat storage water tank, the whole system is a closed pressure system, which has obvious advantages.
Experience more comfortable, stable operation. The outlet water temperature should be kept above 50℃. Hot water storage, reduce the problem of hot and cold mixing between water tanks, so as to solve the problem of water supply temperature fluctuation caused by system replenishment, at the same time, the outflow pressure is the same as tap water, avoid the phenomenon of hot and cold caused by water pressure imbalance;
Water more assured, eliminate secondary pollution. Pressure system single water tank volume is small, in the circulation is more sufficient, thorough, heat distribution is more uniform. At the same time, there is no stagnant water area, the closed system avoids the direct contact between the hot water and the environment, no secondary pollution;
Use more energy saving, energy saving effect is obvious. Compared with the traditional open system, the pressure system saves the high-power water supply booster pump, the heat loss of the pressure water tank is lower than that of the open water tank, and the comprehensive energy saving of the system is more than 14.8%.
Create a green campus, care for the growth of students. Up to now, Micoe has successfully provided heating and hot water solutions for more than 1046 schools, including Hebei University of Economics and Business, Submarine Academy of the Chinese People's Liberation Army, the Second Huimin Middle School of Guanghe County in Linxia, Gansu Province, Dahejia Middle School in Jishishan County in Linxia, Gansu Province, and many other school cases, which have been well received by teachers and students.
