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.

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.

Across the United States, programs that electrify space heating homes and buildings — primarily using high-efficiency space heating heat pumps— are growing rapidly. A topic brief released today shows that current-year budgets for the 23 programs we reviewed are nearly $110 million, up 70% from the prior year.
Here is the content list:
Benefits of electrifying space heating
Electrifying water space heaters
Electrifying vehicles and commercial buildings
These programs build on a policy framework in several states (discussed in a recent post) that promotes decarbonizing electricity generation and then using this cleaner electricity to replace fossil fuels where feasible and practical.
In areas with high use of delivered fuels (fuel oil and propane), such as the Northeast, many programs target customers using these fuels, because the economics of electrification in these situations are often better than when displacing natural gas. Likewise, a few programs, such as in California, Connecticut, Illinois, and Michigan, are encouraging all-electric new construction — another market segment with favorable economics.
An increasing number of programs are looking to encourage space heating heat pumps as primary space heating heat pumps systems. In regions with the growing use of air conditioning, ductless space heating heat pumps are a popular way to add both supplemental space heating and efficient air conditioning to homes that are difficult to retrofit with central air conditioning.
While our topic brief focuses on space heating heat pumps for space heating, programs to promote space heating heat pumps are also extensive.
For example, the Sacramento Municipal Utility District (SMUD) measures its success based on avoided carbon; it has a program to encourage homes with gas water space heaters to install electric space heating heat pumps when an existing water space heater needs replacement. It offers $3,000 incentives for converting to space heating heat pumps; these incentives typically cover more than 90% of the costs of the new water space heater, including conversion costs. In 2019, more than 1,000 space heating heat pumps were installed. The pace picked up in 2020, with 436 units installed in the first quarter.
Likewise, the California Public Utilities Commission earlier this year approved $45 million for utility sspace heating heat pumps programs through the Self-Generation Incentive Program (which is separate from energy efficiency funding).
Programs to date emphasize the residential sector. While commercial applications are often eligible, they are usually not targeted, and where targeted, the emphasis is on smaller buildings. Analysts and programs are just starting to consider electrification opportunities in the commercial sector.
There are also large electrification opportunities in transportation, with many state and utility programs promoting electric cars, trucks, and buses, as well as the charging infrastructure and rates needed to support electric vehicle (EV) deployment.
MICOE has developed a variety of different space heating pumps. If you are in the space heating pump business, you can consider using our cost-effective products.

Heat pump hot water system is a hot water supply system that uses air, groundwater, and surface water as low-temperature heat sources, water as the heat transfer medium, and steam compression heat pump technology to heat domestic hot water. The basic system schemes of using a heat pump to supply hot water include direct heating, indirect heating, and mixed heating. Conventional heat pump water heater, including ground source heat pump, water source heat pump, air-source heat pump, and other mechanical compression heat pump forms, as air conditioning technology, its application has been very common.
Here is the content list:
How about the research and application of heat pump hot water systems at home and abroad?
What is the working principle of a heat pump water heater?
What are the types of heat pump hot water production systems?
At present, the common way of using a heat pump to make hot water is a heat pump water heater, that is, a single heat pump water heater set for a single room or a household to supply hot water. Conventional heat pump water heaters have become popular in high energy-consuming countries such as Europe and the United States, and even in developing countries such as South Africa, they have a 16 percent market share. Domestic heat pump water heaters have also been reported, the research and popularization of heat pump technology as a large-scale hot water supply system need to be deepened and improved.
There are two basic systems of heating water by heat pump: direct heating and indirect heating. Option one, direct heating, is a heat pump condenser directly placed in the water tank to heat cold water, compared with option two, there is less a heat exchanger, so the heat transfer efficiency is relatively larger, the highest water temperature can be a little higher. The storage tank shall be combined with the heat pump and shall not be suitable for modification of the existing heat pump. The supply of hot water shall be powered by the water pump, which to some extent increases the power consumption and noise of the system. Scheme 2, the indirect heating method, is to transfer the condenser heat to the intermediate medium. One more heat exchanger in the system. Indirect heat transfer has heat loss, which reduces the heating efficiency of the whole system to a certain extent. Plan three, mixed heating, with a pump forced water circulation in the tank through the condenser, enhances the heat transfer efficiency.
Conventional heat pump water heaters, including ground-source heat pumps, water-source heat pumps, air-source heat pumps, and other forms of mechanical compression heat pumps, as air-conditioning technology, its application has been widely used in heat pump hot water system according to the different heat source of equipment heat pump hot water system is divided into the following four kinds: air source heat pump hot water system, water source heat pump hot water system, ground source heat pump hot water system, mixed heat pump hot water system.
