First part of solar energy water heater structure is the heat collecting component: The heat collecting component is a heat collection element in the system. It works like the heating element in the electric water heater. Unlike electric water heater or the gas water heater, the solar energy water heater basically uses the radiation energy, thus it is not able to heat the water unless the solar radiation is strong enough. At present, the most common solar collector tube used in the solar powered water heater in Chinese market is all glass evacuated. Solar energy water heart structure is divided into the outer tube and inner tube, the outer wall of the inner tube is coated with a selective absorbing coating. Solar panel collector plate is coated with black chromium absorbing film, and the heat collecting plate is welded by metal tube. Flat plate collector costs slightly higher than evacuated collector. The flat plate collector showed a rising trend in recent years, it especially has unique advantages in high-rise residential balcony type solar energy water heater.
The thermal insulation water tank: The thermal insulation water tank is a hot water storage container. The heated water must be kept in the tank, thus preventing heat loss. The solar energy water heater capacity refers to the water capacity that can be used in the heater, not including the capacity of vacuum tube that cannot be used. For pressure bearing type solar energy water heater, the capacity refers to the medium capacity that can occur heat exchange. The thermal insulation water tank of solar energy water heater is consisted of the liner, insulation layer and the tank shell. The water tank is an important part for water storage, the material strength and corrosion resistance is very important. There are stainless steel, enamel and other materials on the market. The quality of insulation layer materials has a direct relationship with the insulation effect, it is particularly important in the cold season. Thermal insulation is better than polyurethane foaming thermal insulation. The shell is usually made of color steel plate, galvanized plate or stainless steel plate. Water tank insulation requires good insulation effect, corrosion resistance and water clean.
Bracket: Bracket is the supporting shelf for heat collector and heat insulation water tank. It requires firm structure, high stability, resistance to wind and snow, anti-aging and the ability of not getting rusty. Its material is usually stainless steel, aluminum alloy or steel spray.
Connecting pipes: Solar energy water heater which is also called solar powered water heater is a machine that cold water first enters the water storage tank, and then through the collector will the water be heated and then be transferred to the thermal insulation water tank. Heat storage water tank is connected with the indoor cold, hot water pipeline, thus makes the whole system to form a closed loop. To achieve the best working condition, reasonable design, connecting the solar pipeline right is especially important. Solar pipe must do heat preservation processing, to ensure that users can also use solar energy water heater in the cold winter. solar water heater
Control components: General household solar energy water heater needs to be automatically or semi automatically, so the control system is essential. The commonly used controller is automatically water inflow, and stops water influx when being filled with water. It also displays water temperature and water level, and has electricity leakage protection, anti-dry burning function. With the perfect solar energy heater structure, it is commonly accepted by the majority of the houses.
A heat pump is an energy-saving device that uses high-level energy to flow heat from a low-level heat source to a high-level heat source. As the low-level heat source of the heat pump, the air is inexhaustible and inexhaustible. It is available everywhere and can be obtained free of charge. Moreover, the installation and use of air source heat pumps are relatively convenient.

What types can air source heat pumps be divided into?
What are the characteristics of air source heat pumps?
How to select an air source heat pump?
According to the capacity of the unit, it is divided into small-sized units, medium-sized units, large-scale units, etc.
According to the unit combination form, it is divided into the integral unit (a unit that is composed of one or several compressors sharing a water-side heat exchanger is called an integral unit) and a modular unit (a unit composed of several independent modules, called It is a modular unit).
1. The air source heat pump system integrates cold and heat sources, no special refrigeration room or boiler room is required. The unit can be placed on the roof or the ground arbitrarily, which does not occupy the effective use area of the building, and the construction and installation are very simple.
2. The air source heat pump system has no cooling water system, no cooling water consumption, and no cooling water system power consumption. In addition, many cases of Legionella infection caused by cooling water pollution have been reported. From the perspective of safety and health, considering air source heat pumps also has obvious advantages.
3. Since the air source heat pump system does not require a boiler, a corresponding boiler fuel supply system, a dust removal system, and a flue gas discharge system, the system is safe and reliable and does not pollute the environment.
4. The air source heat pump cold (hot) water unit adopts a modular design, and there is no need to set up a standby unit. During the operation, the computer automatically controls and adjusts the operation status of the unit to adapt to the output power to the working environment.
5. The performance of the air source heat pump will vary with outdoor climate changes.
6. In places with low outdoor air temperature in northern China, an auxiliary heater is required due to insufficient heat supply from the heat pump in winter.
1. Look at the energy efficiency label of the air source heat pump. The air source heat pump host produced by the regular manufacturer will have the energy efficiency label. This energy efficiency label is authorized by the national environmental protection after review. The purpose is to provide users and consumers with the information necessary for decision-making when purchasing air source heat pumps, so as to guide and help consumers choose energy-efficient air source heat pump products.
2. Understand the cooling and heating efficiency of air source heat pumps. Under normal circumstances, the cooling and heating efficiency of air source heat pumps will also affect the later use of electricity costs. In cooling and heating conditions, the higher the efficiency of the air-source heat pump, the more power-saving.
3. It is also more important to look at the noise ratio of air source heat pump heating than air source heat pump, because the noise of air source heat pump is too loud, which will affect the surrounding environment.
It is the responsibility of each manufacturer to produce an industrial air source heat pump that meets the standards, so as to ensure the safety of the use of air-source heat pump and the healthy development of the air source heat pump market. MICOE many tests on air source heat pumps before they leave the factory, and the quality qualification rate is guaranteed.

The hot water heat pump is a high-efficiency energy-saving device that makes full use of low-grade heat energy. To understand the working principle of a hot water heat pump, you must understand the working principle of an air source heat pump. The working principle of a hot water heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. Hot water heat pump only consumes a small amount of reverse cycle network, and can obtain a large amount of heat supply, which can effectively reduce the low grade that is difficult to apply. Heat energy is used to achieve energy-saving purposes. Do you know how to buy a suitable hot water heat pump?
Here is the content list:
What is the working principle of a hot water heat pump?
What type can hot water heat pump be divided into according to its application?
What is the sales model of the hot water heat pump market?
The performance of a hot water heat pump is generally evaluated by the coefficient of refrigeration (COP coefficient of performance). The coefficient of refrigeration is defined as the ratio of the heat transferred from a low-temperature object to a high-temperature object and the required power. Usually, the refrigeration coefficient of an air source heat pump is about 3-4, that is to say, a hot water heat pump can transfer heat energy 3 to 4 times of its own required energy from low-temperature objects to high-temperature objects. Therefore, the hot water heat pump is essentially a heat-increasing device. It consumes a small part of the electric energy when working, but can extract 4-7 times the electric energy from the environmental medium (water, air, soil, etc.) to increase the temperature. Utilization is also the reason for the energy-saving of air source heat pumps.
According to different types of heat sources, hot water heat pumps can be divided into air source heat pumps, water source heat pumps, ground source heat pumps, dual-source heat pumps (combination of water source heat pumps and air source heat pumps), etc.
When the air source heat pump is in operation, the evaporator absorbs heat from the environmental heat in the air to evaporate the heat transfer working fluid. The working fluid vapor is compressed by the compressor and the pressure and temperature rise, and the high-temperature vapor passes through a special ring bonded to the outer surface of the water storage tank. When a hot water heat pump is piped, the condenser condenses into liquid and transfers the heat to the water in the air source heat pump storage tank.
The working principle of the water source heat pump technology is: by inputting a small amount of high-grade energy (such as electric energy), the low-temperature heat energy is transferred to the high-temperature level. The water body is used as the heat source of heat pump heating in winter and the cold source of air conditioning in summer. In summer, the heat from the building is “taken out” and released into the water body. Because the water source temperature is low, the heat can be taken away efficiently to achieve summer The purpose of building indoor cooling.
The sales channels of the hot water heat pump market are mainly three types: the self-operated mode, the agency model, and the mixed mode of the two. The direct operation mode of a hot water heat pump is that the company opens branches or dispatches business personnel to operate directly. The direct operation model is limited by the strength and capability of hot water heat pump companies, making it difficult to become stronger and bigger. The model of the distribution system is that manufacturers set up dispatch agencies in various places to expand channels. In the early stage, business personnel is dispatched to conduct counseling work, and in the later stage, the dealers complete market operations independently.
It is the responsibility of each manufacturer to produce a hot water heat pump that meets the standards, so as to ensure the safety of the electricity supply. MICOE conducts many tests on durable hot water heat pumps before they leave the factory, and the quality qualification rate is guaranteed.
