What is an all-in-one heat pump? All-in-one heat pumps transfer heat from one place to another. Air source all-in-one heat pumps move heat between the air inside a home and the air outside the home, while ground source all-in-one heat pumps (known as geothermal all-in-one heat pumps) transfer heat between the air inside a home and the ground outside a home. We will focus on air source all-in-one heat pumps, but the basic operation is the same for both.

All-in-one heat pump basis
How an all-in-one heat pump works - cooling mode?
How an all-in-one heat pump works - heating mode?
One very important point to understand when answering the question “how do all-in-one heat pumps work?” is that all-in-one heat pumps do not generate heat – they move heat from one place to another. A furnace creates heat that is distributed throughout a home, but an all-in-one heat pump absorbs heat energy from the outside air (even in cold temperatures) and transfers it to the indoor air. When in cooling mode an all-in-one heat pump and an air conditioner are functionally identical, absorbing heat from the indoor air and releasing it through the outdoor unit.

STEP 1
The liquid refrigerant is pumped through an expansion device at the indoor coil, which is functioning as the evaporator. Air from inside the house is blown across the coils, where heat energy is absorbed by the refrigerant. The resulting cool air is blown throughout the home's ducts. The process of absorbing the heat energy has caused the liquid refrigerant to heat up and evaporate into gas form.
STEP 2
The gaseous refrigerant now passes through a compressor, which pressurizes the gas. The process of pressurizing the gas causes it to heat up (a physical property of compressed gases). The hot, pressurized refrigerant moves through the system to the coil in the outdoor unit.
STEP 3
The expansion valve reduces the pressure of the warm liquid refrigerant, which cools it significantly. At this point, the refrigerant is in a cool, liquid state and ready to be pumped back to the evaporator coil in the indoor unit to begin the cycle again.
An All-in-one heat pump in heating mode operates just like cooling mode, except that the flow of refrigerant is reversed by the aptly named reversing valve. The flow reversal means that the heating source becomes the outside air (even when outdoor temperatures are low) and the heat energy is released inside the home. The outside coil now has the function of an evaporator, and the indoor coil now has the role of the condenser. The physics of the process is the same. Heat energy is absorbed in the outdoor unit by the cool liquid refrigerant, turning it into cold gas.
MICOE has developed a variety of different all-in-one heat pumps. If you are in the all-in-one heat pumps business, you can consider using our cost-effective products.

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.

If you have a pool in your home, unless you only use it in the summer, you will need a swimming pool heat pump. A Swimming pool heat pump is a part of all in one heat pump. Is it worth it? Or how to choose the best way to get the most out of your hot pool pump. If you're interested, here are some details.
Here is the content list:
How does the swimming pool heat pump work?
How do determine the efficiency of the swimming pool heat pump?
How to install and maintain the swimming pool heat pump?
The Swimming pool heat pump uses electricity to capture heat and move it from one place to another. They don't generate heat. As the pool pump circulates the swimming pool's water, the water drawn from the pool passes through a filter and the swimming pool heat pumps. The swimming pool heat pump has a fan that draws in the outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating through the heater. The heated water then returns to the pool. The hot gas, as it flows through the condenser coil, returns to liquid form and back to the evaporator, where the whole process begins again.
Higher efficiency swimming pool heat pumps usually use scroll compressors versus the reciprocal compressors of standard units. Swimming pool heat pumps work efficiently as long as the outside temperature remains above the 45ºF–50ºF range. The cooler the outside air they draw in, the more energy they use. However, since most people use outdoor swimming pools during warm and mild weather, this usually isn't an issue.
The energy efficiency of the swimming pool heat pump is measured by a coefficient of performance (COP). The higher the COP number, the more efficient. However, there is no standard test for measuring the COP. Therefore, you really can't compare the COPs of different models unless you know that the manufacturers used the same test for each model. For example, the same heat pump will operate at a higher COP when the outside air temperature is higher.
Typically, manufacturers measure the COP by testing a swimming pool heat pump with an outdoor temperature of 80ºF and pool temperature of 80ºF. COPs usually range from 3.0 to 7.0, which converts to an efficiency of 300%–700%. This means that for every unit of electricity it takes to runs the compressor, you get 3–7 units of heat out of the heat pump.
Since it is a part of all-in-one heat pump, proper installation and maintenance of your swimming pool heat pump can optimize its efficiency. It's best to have a qualified pool professional install the heater, especially the electric hook-up, and perform complicated maintenance or repair tasks. Read your owner's manual for a maintenance schedule and/or recommendations. You'll probably need to tune up your pool heater annually. Because a swimming pool heat pumps many moving and electrical parts, it will probably require periodic service by an air conditioning technician. With proper installation and maintenance, swimming pool heat pumps can last 10 or more years. Use it combines with an all-in-one heat pump, keep all parts of your home warm.
The pool hot water pump will help you increase the use of your pool except in the summer, especially if you enjoy swimming. And it is a very interesting thing that, enjoy the hot gas from the pool in the winter. If you are in the swimming pool heat pumps business, you can consider our cost-effective products.
