The all-in-one heat pump is a water heater that can provide the whole family with different hot water needs with large water volume, high water pressure, and constant temperature 24 hours a day, while consuming the least energy to complete the above requirements.
Here is the content list:
The working principle of the all-in-one heat pump
Features of all-in-one heat pump
Instructions for use of all-in-one heat pump
A complete all-in-one heat pump consists of 2 main parts: Manufacture the air-conditioning part and the heating hot water part. But in fact, these two parts are closely linked, inseparable, and must work at the same time. That is, while heating hot water, it cools the kitchen. In other words, while refrigerating the kitchen, it is also heating hot water.
Its internal structure is mainly composed of four core components: compressor, condenser, expansion valve, and evaporator.
The working process is as follows: the compressor compresses the returning low-pressure refrigerant and turns it into high-temperature and high-pressure gas and discharges it. The high-temperature and high-pressure refrigerant gas flow through the copper pipe wound outside
the water tank, and the heat is transferred to the water tank through the copper pipe to cool down. The down refrigerant becomes liquid under the continuous action of pressure. After passing through the expansion valve, it enters the evaporator. Because the pressure of the evaporator drops suddenly, the liquid refrigerant quickly evaporates and becomes a gaseous state, and absorbs a lot of heat. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator, and the temperature of the airdrops rapidly, turning into the cold air and discharged into the kitchen. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.
1. Safety, because it is not directly heated by electric heating elements, compared with electric water heaters, it eliminates the potential safety hazards of electricity leakage; Compared with gas water heaters, there are no safety hazards such as gas leakage or carbon monoxide poisoning, so it has better safety performance.
2. Comfortable, the all-in-one heat pump is a heat storage type. The heating function is automatically activated according to the temperature in the water tank to ensure a sufficient supply of hot water for 24 hours. Therefore, there will be no problems that cannot satisfy multiple taps at the same time like a gas water heater. The problem is that the electric water heater has a small capacity and many people need to wait for a bath.
3. Save money, because its power consumption is only a quarter of that of an equivalent electric water heater, which is equivalent to using the same amount of hot water, using an all-in-one heat pump, and the electricity bill is only a quarter of the electric heating.
4. Kitchen refrigeration, is the biggest advantage, ordinary water heaters simply cannot have the function of refrigeration. If the kitchen needs additional cooling function, you need to buy a kitchen air conditioner. Because the kitchen has oily fume, it is a special environment, so the kitchen air conditioner is different from the ordinary air conditioner, and the price is much more expensive.
5. Green and environmentally friendly, the gas water heater heats hot water by burning combustible gas, and at the same time emits a large amount of carbon dioxide, sulfur dioxide, and other harmful exhaust gas. The all-in-one heat pump just transfers the heat from the surrounding air to the water, completely achieving zero emissions, and has almost no impact on the environment. It is a true environmentally friendly water heater.
6. Low-carbon fashion, as energy-saving and emission reduction, has become the trend of the times, saving energy and reducing carbon emissions is the most fashionable way of life.
Installation: The all-in-one heat pump is usually installed on the balcony of the kitchen, and the air outlet is connected with the kitchen through the air duct so that the cold air blown out can directly enter the kitchen to achieve the cooling effect. During installation, only the hot and cold water outlets are connected with the reserved hot and cold water in the house, and they can be used by connecting them. The installation is very simple.
Operation: All-in-one heat pumps mostly use microcomputer intelligent controllers, which have time setting, timing switch function, water temperature setting, ventilation setting, overheating protection, and other intelligent control functions. However, most of the functions have been set by the manufacturer at the factory. Just use the default values. Basically, you only need to set the temperature you need (usually set at 45-50 degrees) and you can use it.
It is the responsibility of each manufacturer to produce an industrial all-in-one heat pump that meets the standards, so as to ensure the safety of the use of all-in-one heat pumps and the healthy development of the all-in-one heat pump market. MICOE many tests on all-in-one heat pumps before they leave the factory, and the quality qualification rate is guaranteed. If you are in the all-in-one heat pump business, you can consider our cost-effective products.

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.
Nowadays, more and more communities choose space heating heat pumps for heating, and the government is also strongly supporting this policy. So, why choose a space heating heat pump?
Here is the content list:
Advantages of space heating heat pump
How to choose the type of space heating heat pump?
How to buy a space heating heat pump?
The energy efficiency ratio is high. One part of electricity supplies three parts of heat. The space heat pump is essentially a heat-lifting device that absorbs heat from the surrounding environment and transfers it to the object to be heated. At work, first, input 1 part of electric energy to drive the compressor to do work, and then absorb a large amount of heat energy from the outside environment temperature, and release heat in the condenser through the refrigerant circulation system. It is precisely because of the existence of the "law of conservation of energy" that the 1 share of electrical energy input to the compressor can always be converted into 1 share of heat energy, and the large amount of heat energy absorbed from the external environment becomes an additional harvest. In other words, the main force that really heats water is not the input of electrical energy, but the free "heat" in the air.
Electricity is not expensive, and ordinary households can afford it. The initial investment of space heating heat pump heating products is indeed much higher than that of electric heating, but the operating costs are also much lower, the comfort is better, and it is safe.
1. The model should be selected according to the larger one of the heating load in winter and the cooling load in summer.
2. When the unit is used as the auxiliary heat source of the solar hot water system at the same time, it should be determined according to the maximum specifications that meet the requirements of the three.
3. On the premise of meeting the above requirements, the equipment capacity should not be over-enlarged.
The purchase of space heating heat pumps can be selected from the following seven aspects:
1. Appearance inspection: The outer surface of the paint should be uniform, bright in color, without falling off, with no dents, severe scratches, or pressing marks, etc; The outer shell should be made of fluorine titanium plate.
2. Strictly prevent counterfeit and inferior products, it is best to buy directly from the manufacturer.
3. The accessories should be complete.
4. Inspection of the power plug: the wiring must be firm, and of course it is better if the line is thick and hard. If it is too small, it will heat up after power on for a while, and it may even cause a fire.
5. Power-on test and constant temperature performance check whether the indicator light is on, and whether the machine is humanized setting does not require people to normally open and normally close. Whether there is overheating protection function and whether the defrosting is good.
6. Noise: The smaller the noise of the heat pump water heater, the better.
7. If the space heating heat pump has the function of magnetization or ion activation, the effect will be better.
It is the responsibility of each manufacturer to produce an industrial heat pump that meets the standards, so as to ensure the safety of the use of heat pumps and the healthy development of the heat pump market. MICOE many tests on heat pumps before they leave the factory, and the quality qualification rate is guaranteed. If you are in the heat pump business, you can consider our cost-effective products.
