A heat pump is part of a heating and cooling system. Like an air conditioner, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.
HOW A HEAT PUMP WORKS
A.COOLING MODE
One of the most important things to understand about heat pump operation and the process of transferring heat is that heat energy naturally wants to move to areas with lower temperatures and less pressure. Heat pumps rely on this physical property, putting heat in contact with cooler, lower pressure environments so that the heat can naturally transfer. This is how a heat pump works.
B.HEATING MODE
A 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 are the same. Heat energy is absorbed in the outdoor unit by cool liquid refrigerant, turning it into cold gas. Pressure is then applied to the cold gas, turning it to hot gas. The hot gas is cooled in the indoor unit by passing air, heating the air and condensing the the gas to warm liquid. The warm liquid is relieved of pressure as it enters the outdoor unit, turning it to cool liquid and renewing the cycle.
Now, more and more families are making the preparation for the Winter, Like installing the heat pump for house heating and hot water.

The heat pump water heaterabsorbs the low-temperature heat in the air, vaporizes the cold medium, and then compresses it through the compressor to increase the temperature, and then converts it through the heat exchanger to heat the water, and the compressed high-temperature heat energy is used to heat the water temperature.
What is the difference between a heat pump water heater and an air conditioner?
What are the advantages of heat pump water heater and compared with gas water heater?
What are the advantages of heat pump water heater compared to electric water heater?
When a general air conditioner is refrigerating, it absorbs the heat in the room through the phase change of the refrigerant in the evaporator (liquid to gas), and then realizes cooling through the heat release of the outdoor condenser. His heat exchange equipment is mainly finned heat exchangers. The heat pump water heater converts the low-grade energy in the air into high-grade energy that we can use. The heat is obtained by absorbing heat from the air through the phase change (endothermic) of the refrigerant in the evaporator, and then releasing heat through the indoor condenser (or jacket heat exchanger). This is his heating state. Its cooling is the same as that of general air conditioners, except that the heat exchanger may be different. General air conditioners use ordinary finned heat exchangers.
Gas water heaters heat the water temperature by burning combustible gas, and at the same time, will produce greenhouse gases such as carbon dioxide. If the continuous large amount of carbon dioxide on the earth exists in the air for a long time, it will produce a greenhouse effect on the earth's environment! The heat pump water heater only heats the water temperature with the heat in the air, and will not emit any toxic and harmful gases. In the era of energy saving and emission reduction, it is a water heater that is truly energy-saving and environmentally friendly. Secondly, gas water heaters may leak gas and cause human carbon monoxide poisoning accidents. Therefore, the safety of empty heat pump water heater is better than that of gas water heater.
We can compare heat pump water heater with electric water heater. Electric water heaters are heated with electric heating rods. The heat pump water heater heats the water temperature by absorbing heat from the air. The heat generated by the heat pump water heater consumes 1 kWh of electricity equivalent to the heat generated by the electric water heater consuming 4 kWh of electricity. In terms of energy saving, heat pump water heaters are far more energy efficient than electric water heaters. Second, in terms of security. The heat pump water heater just transfers the heat after compression heating to the water tank for heating, so the water and electricity are completely isolated. The electric water heater electric heating rod is directly heated in the water. Therefore, leakage accidents are easy to occur!

Winter has arrived, and people tend to use heat pumps as heating machines. If the heat pump unit can be installed reasonably, the service life and heating capacity of the heat pump will be improved. Let Jnod tell you how to install it, see below:
1. Unit installation location planning
1) The installation requirements of the heat pump main unit are similar to the installation requirements of the outdoor unit of the air conditioner. It can be installed on the roof, balcony, and ground. The air outlet should avoid the windward direction.
2) The distance between the main unit (wind from the side) and the surrounding walls or other obstructions should not be too small. There should be no obstructions within 1 meter of the air outlet, and ensure that the heat exhaustion and suction of the heat exchanger are not hindered.
3) There should be no obstructions within 1 meter of the air inlet of the main unit (top air outlet), and no obstructions within 2 meters of the air outlet to ensure that the heat exhaustion and suction of the heat exchanger of the main unit are not hindered.
When the unit is installed under the eaves or there are horizontal obstacles above the unit, the installation location of the unit must be in a well-ventilated place, otherwise it is easy to short-circuit the air flow, resulting in poor heat dissipation capacity of the unit.
2. Unit installation environment control
1) Try not to place it in direct sunlight.
2) Not on the window sill of the bedroom or near the bedroom.
3) There is enough distance between the air inlet and outlet to facilitate heat dissipation.
4) Places that can withstand more than 2-3 times the weight of the outdoor unit.
5) A place where there is no oily smoke or other corrosive gas.
6) A place that does not affect other factors or the environment.
The hot water produced by the heat pump water heater is directly sent to the user through the circulation system as hot water supply or small area heating is carried out by using the fan exhaust pipe. Air source Heat Pump Hot Water Heater is currently the best solution for large, medium and small hot water centralized supply systems in school dormitories, hotels, bathing centers and other places.
Why choose Heat Pump Hot Water Heater?
Where is the better place to install the main unit and water tank of the Heat Pump Hot Water Heater?
What is Heat Pump Hot Water Heater?
1. Safety
The Heat Pump Hot Water Heater has the potential safety hazard of leakage, and the gas water heater has the danger of gas poisoning. Compared with these two water heaters, the air energy water heater exchanges heat through the medium, which avoids the direct contact between the electric heating element and the water, which solves the problem. Second, because the raw material of Heat Pump Hot Water Heater is air, it also eliminates the possibility of gas explosion or gas poisoning in gas water heaters, allowing people to use it more comfortably and worry-free.
2. Environmental protection
Energy saving and environmental protection complement each other, and environmental protection is another plus point of Heat Pump Hot Water Heater in its energy saving advantages. First of all, the air energy water heater uses electric energy to compress air to produce heat energy, and does not emit waste gas and toxic gas, which is not only safe, but also creates a pollution-free bathing environment. Secondly, the use time of Heat Pump Hot Water Heater is as long as 15-20 years. The long lifespan can not only reduce the cost and trouble for people to replace the water heater, but also reduce waste production in a sense, which is also an important aspect of environmental protection. aspect.
Answer: The Heat Pump Hot Water Heater is the best choice to install it on the balcony or bay window. The advantage is that it does not occupy indoor space, it is safe and stable, and the entire hot water piping system will have sufficient hot water; the host is installed in a ventilated and sunny place. it is good. Bay windows or wall hangings can allow the host to absorb heat from the air as much as possible to improve heating efficiency. It is understood that more than 90% of users will choose this installation method.
All-in-one Heat Pump Water Heaters and Split Type Heat Pump Water Heater are included in this hot water series, both on/off and inverter is available. Eco-friendly R32 and R410A refrigerant are adopted, as well the world famous Mitsubishi compressor. This series is widely used in residential and commercial hot water projects.

With the widely known advantages of air energy heat pump products such as cleanliness, environmental protection, energy saving, stability and comfort, heating with Heating and Cooling Heat Pump products has become a trend. More and more northern == home users and schools, hotels, hospitals When transforming the original heating system in other places, choose to use Heating and Cooling Heat Pump.
Compared with ordinary central air conditioning refrigeration and gas wall-hung boiler heating, what are the advantages of Heating and Cooling Heat Pump?
What are the advantages of using the Heating and Cooling Heat Pump?
What is the working principle of Heating and Cooling Heat Pump?
The common heating and cooling equipment on the market is mainly fluorine system heating and cooling air conditioning or the combination of gas wall-hung boiler heating and central air conditioning refrigeration.
The main advantage of Heating and Cooling Heat Pump compared to ordinary heating and cooling air conditioners is high comfort. The fluorine system heating and cooling air conditioner directly controls the indoor temperature through the flow of the refrigerant, and the refrigerant directly exchanges heat with the air. This heat exchange method has two disadvantages: First, the temperature of the air outlet of the air conditioner is very low or very high (7°C-12°C during cooling, 40°C-50°C during heating), the body feels very bad, and it is bitingly cold in summer. The winter is hot and dry; second, although the fluorine system air conditioner has a relatively fast cooling and heating speed, it will also cause a large amount of moisture in the air to be taken away due to the rapid heating and cooling speed, resulting in excessive indoor dehumidification and drying.
1) The unit of Heating and Cooling Heat Pump has high energy efficiency ratio, energy saving and electricity saving.
2) The water temperature of the Heating and Cooling Heat Pump is generally constant at 12-22°C, which is 7°C for the water supply in summer, 12°C for the return water, 45°C for the water supply in winter, and 40°C for the return water, and the temperature difference between them is small. , so the unit has less work and more energy.
During the operation of Heating and Cooling Heat Pump, the evaporator absorbs heat from the ambient heat energy in the air to evaporate the heat transfer working medium. After the working medium vapor is compressed by the compressor, the pressure and temperature rise. When the high-temperature vapor passes through the special annular pipe bonded on the outer surface of the water storage tank, the condenser condenses into liquid and transfers the heat to the water in the water storage tank of air source heat pump.

The heat pump water heater uses a heat pump to absorb the air heat source to produce hot water. The energy saving efficiency is more than 3 times that of the electric water heater. It is more energy efficient than the solar water heater.
What is a direct heat pump water heater?
What are the characteristics of direct heat pump water heaters?
What is the main structure of the direct heat pump water heater?
The direct heat pump water heater is also known as the fast or fast heat pump water heater. The basic characteristics of the direct heat pump water heater are: cold water and superheated water, as long as the tap is turned on, the energy source will continuously supply hot water within a few seconds. Turn off the faucet when you don't need hot water.
According to different heating forms, direct heat pump electric water heaters can be divided into the following three types:
①, bare electric wire heating electric water heater;
②, electric film heating electric water heater;
③, electric heating tube heating electric water heater.
The heater of the direct heat pump water heateris set in a tank frame, which cannot withstand too high water pressure. At the same time, the left and right poles of the tank frame and the two poles introduced by the heating wire will be affected by water pressure for a long time. be damaged. Therefore, direct heating heat pump water heaters cannot be made into the post-system, but are all made into the front-system. In addition, in order to ensure the safe use of direct-heat heat pump water heaters and no dry burning occurs, a pressure sensing activation switch with water flow as a signal is installed at the cold water inlet, and the pressure sensing activation switch diaphragm can withstand the pressure. It is limited and cannot withstand pressure for a long time, so direct heat pump water heaters are generally made into the former system.
A typical direct heat pump water heater is mainly composed of a heating tank plate, a pressure sensor, a power regulator, a water volume adjustment faucet, a water inlet pipe and a water outlet pipe component, among which the heating tank plate is the key component of the direct heat pump water heater. It consists of a groove weight, a sealing ring, a cover and an electric heating element, and the electric heating element is located in the groove of the groove plate.
The direct heat pump water heater works by direct conduction heating. Since the electric heating element is placed in the groove of the groove plate, when the cold water flows through the groove, it can directly flow through the surface of the heating element to be heated. And because the water tank is like a snake, the cold water flowing into the water inlet is gradually heated, and hot water with a higher temperature can be obtained at the water outlet.
