The heat pump is a high-efficiency energy-saving device that makes full use of low-grade heat energy. A hot water heat pump is an important application.
Here is the content list:
1. What is the working principle of a hot water heat pump?
2. What are the advantages of hot water heat pumps?
3. What are the disadvantages of hot water heat pumps?
The working principle of the hot water heat pump heating in winter: the hot water heat pump takes the groundwater from the water extraction well and sends it to the hot water heat pump unit. The unit absorbs the low-grade groundwater of heat energy, and then it is sent back to the ground and the earth to heat again after being charged well. Exchange to increase heat energy, and then reuse.
The liquid refrigerant in the hot water heat pump unit absorbs the low-level heat energy of the groundwater in the evaporator and evaporates into a low-temperature and low-pressure gaseous refrigerant. The compressor (using a fully enclosed flexible scroll compressor with reliable operation and high heating efficiency) compresses it into a high temperature and high-pressure gaseous refrigerant, and then sends it out of the condenser. The high-temperature and high-pressure gaseous refrigerant in the condenser transfer heat to the building's circulating water (geothermal or heating radiator) through heat exchange. After dissipating the heat to the building, it condenses into a liquid state and then returns to the hot water heat pump evaporator to repeat. The process of heat absorption and heat exchange.
(1) Easy to maintain
The range of water temperature fluctuation is much smaller than that of air. The relatively constant water temperature makes the operation of the hot water heat pump unit more stable; it adopts full computer control and has a high degree of automation. Because the hot water heat pump system is simple, the unit has few parts, and the operation is stable, the maintenance cost is low and the service life is long.
(2) Renewable energy
The hot water heat pump uses the solar energy stored in the earth's water body as the heat source and uses the low-temperature water after the natural heat dissipation of the earth's water body as the cold source, so the hot water heat pump uses clean and renewable energy.
(3) Save water and land
The hot water heat pump uses surface water as a source of cold and heat and emits or absorbs heat to it, without consuming water resources and causing no pollution to it. At the same time, the hot water heat pump saves the boiler room and other facilities, saving construction space.
To protect the groundwater source from pollution, some cities prohibit the extraction and utilization; hot water heat pumps that use water from rivers and lakes are also affected by many factors such as seasonal drops in water levels. Therefore, there are many restrictions on the use conditions of hot water heat pumps.
It is the responsibility of each manufacturer to produce hot water heat pumps that meet the standards, to ensure the healthy development of the hot water heat pumps market.

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.
