working principle

A complete integrated air source water heater includesTwo main parts:

Manufacturing the air conditioning section and heating the hot water section. But in fact, these two parts are closely connected and inseparable, and must work together. Simultaneously heating hot water and cooling the kitchen. Or in other words, while cooling the kitchen, hot water is also being heated.

Its internal structure mainly consists of four core components: compressor, condenser, expansion valve, and evaporator.

The workflow is as follows: the compressor compresses the low-pressure refrigerant flowing back and turns it into high-temperature and high-pressure gas, which is then discharged. The high-temperature and high-pressure refrigerant gas flows through the copper tube wrapped around the outside of the water tank, and the heat is conducted into the water tank through the copper tube. The cooled refrigerant becomes liquid under continuous pressure and enters the evaporator after passing through the expansion valve. Due to the sudden decrease in pressure of the evaporator, the liquid refrigerant quickly evaporates into a gaseous state and absorbs a large amount of heat. At the same time, under the action of the fan, a large amount of air flows over the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator. The air temperature rapidly decreases and becomes cold air, which is discharged into the kitchen. Subsequently, the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.

From the above working principle, it can be seen that the working principle of the integrated air source water heater is somewhat similar to that of air conditioning. It applies the reverse Carnot principle, which absorbs a large amount of low-temperature heat energy from the air, compresses it into high-temperature heat energy through the compressor, and transfers it to the water tank to heat the water. The entire process is an energy transfer process (from air to water), not an energy conversion process, without heating hot water through electric heating elements or burning combustible gases.

Air source heat pump technology

A heat pump water heater is a new type of hot water and heating heat pump product that can fully replace boilers as heating equipment and hot water devices. Compared with traditional solar energy, heat pump water heaters can not only absorb heat from the air, but also absorb solar energy. A heat pump water heater absorbs heat through refrigerant temperature difference and compresses and heats with water through a compressor, greatly improving thermal efficiency and fully utilizing new energy. It combines the advantages of electric water heaters and solar water heatersA new type of water heater integrated into one. At present, there are three types of heat pump water heaters: air source heat pump water heater, water source heat pump, and solar energy type, which are one of the equipment for exploring and utilizing new energy.

Air source heat pump is one of the products in the world today, which uses refrigerant as a medium. The refrigerant absorbs energy from the air in the fan coil, and then compresses and heats it up through the compressor. The heat is transferred to the water through the heat exchange device to produce hot water. The hot water is then sent to the user's radiator for heating or directly used for hot water supply through the water circulation system.

Development of Air Source Heat Pump

Air source heat pump technologySince its invention in 1924, it has not been fully recognized and utilized by humans for a long time. Heating still relies on traditional methods such as gas or electric heating, as they are relatively simple and direct. But it was not until the 1960s, after the global energy crisis, that sufficient attention was paid to the sustainable development of the world economy. To leave energy and energy resources for future generations, we must pay attention to energy conservation and rational use. So countries around the world have increased their research and development efforts and promoted heat pump technology, so heat pump technology is now widely used.

Advantages of heat pump products compared to boilers

1. High thermal efficiency: The average thermal efficiency of the product is over 300% throughout the year, while the thermal efficiency of the boiler will not exceed90%.

2. Low operating costs: Compared with oil and gas boilers, it can save an average of 70% of energy throughout the year. With the decrease in electricity prices and the increase in fuel prices, the advantages of operating costs are becoming increasingly prominent.

3. Environmental Protection: The heat pump product has no combustion emissions, and the refrigerant used is the environmentally friendly refrigerant R22.

4. Safe operation, no need for on duty: Compared with fuel boilers, it is safe to operate and fully automated, without the need for personnel on duty.

Advantages of heat pumps compared to solar products

1. Widely applicable, the product is suitable for temperatures ranging from -10 ℃ to 40 ℃, and can be used all year round without being affected by harsh weather such as shade, rain, snow, and winter nights. It can be used normally.

2. Continuous heating is possible. Compared with traditional solar water storage systems, heat pump products can provide continuous heating and water supply to meet user needs.

3. Low operating cost: Compared with conventional solar energy, the operating cost is higher in spring, summer, autumn, and winter when the sunshine is good. However, on rainy days and nights, the thermal efficiency is much higher than that of solar energy's electric assisted heating. On average, the annual energy consumption of conventional solar assisted systems is much higher than the total annual energy consumption of products.

4. Easy installation: Air source heat pumps occupy a small space and have a similar appearance to outdoor air conditioning units. They can be directly connected to insulated water tanks or heating pipelines, making them suitable for high-rise buildings in large and medium-sized cities and addressing large-scale heating issues.

The difference between heat pump products and solar products

In terms of working principle, it does not belong to traditional solar products. There is a significant difference between heat pump products and conventional solar products. Commonly used solar products use water as the medium and rely on direct sunlight or radiation to achieve heating effects. However, this product uses refrigerant to absorb heat energy and solar radiation from the air, and exchanges heat with water through compression heating by a compressor to achieve heating effects. Therefore, the principle of the product is the same as that of air conditioning.

Air source hot water unitSix major advantages:

1）safety

Since it does not use electric heating elements for direct heating, it eliminates the safety hazard of electric leakage compared to electric water heaters; Compared to gas water heaters, there are no safety hazards such as gas leaks or carbon monoxide poisoning, making them safer.

2）comfortable

The integrated air source water heater is a heat storage type, and the heating function automatically starts according to the temperature inside the water tank to ensure hot water24-hour sufficient supply, so there will be no problem like gas water heaters that cannot meet the needs of multiple hot water users at the same time, nor will there be problems like electric water heaters with small capacity and waiting for multiple people to take a shower. Ready to use hot water, with a large output and stable outlet temperature, meeting all your expectations for hot water.

3）save money

Due to its power consumption being only a quarter of that of an equivalent electric water heater, which is equivalent to using the same amount of hot water, using a modular air source water heater only requires a quarter of the electricity cost for electric heating. as oneFor a family of four, the normal usage of hot water is around 200L/day. Heating with an electric water heater costs about 4 yuan/day, while a modular air source water heater only costs about 1 yuan/day, saving about 1000 yuan in electricity bills per year.

4）Kitchen cooling

This is a major advantage, ordinary water heaters (such as electric heating, gas water heaters, solar water heaters, etc.) simply cannot have the function of cooling. If the kitchen needs to add additional cooling function, it is necessary to buy a kitchen air conditioner. Due to the presence of cooking fumes in the kitchen, it is a special environment, so kitchen air conditioning is different from ordinary air conditioning and the price is much higher. (The general price isOver 4000 yuan

5）green and environmentally friendly

The so-called heat pump is a mechanical device that uses artificial technology to convert low-temperature heat energy into high-temperature heat energy to achieve heating effect. Heat pump is a low-temperature heat sourceThe natural air, groundwater, river water, seawater, sewage, etc. in the surrounding environment absorb heat and have almost no impact on the environment, making it a truly environmentally friendly water heater.

6）Low carbon fashion

In today's era where energy conservation and emission reduction have become the trend of the times, saving energy and reducing carbon emissions is a way of life. As mentioned earlier, the integral air source water heater adopts the inverse Carnot principle, which transfers energy from the air to the water instead of directly heating it with electric heating elements. Therefore, its energy efficiency can reach that of an electric water heaterFour times, that is, heating the same amount of hot water, consumes one-quarter of the electricity of an electric water heater, greatly saving electricity consumption. 70% of China's electricity is generated through coal-fired power plants, and saving electricity means reducing carbon emissions.

Regular inspection and maintenance

Any problem with any component of a device can affect its normal use.

Regularly check whether the power supply and electrical system wiring of the air source heat pump hot water unit are secure, and whether there are any abnormal movements of the electrical components. If there is any abnormality, it should be repaired and replaced in a timely manner. Check if the water pump and water valve are working properly, and if there is any leakage in the water pipeline and water pipe joints.

Moreover, it is necessary to regularly check whether the water system's replenishment, water tank safety valve, liquid level controller, and exhaust device are working properly, in order to prevent air from entering the system and reducing the water circulation, thereby affecting the heating capacity and reliability of the unit's operation.

When using and maintaining, it should be noted that all safety protection devices and system settings inside the unit should be kept at their pre factory settings, and should not be adjusted by oneself.

Regular cleaning system

During use, we should regularly clean the water circuit filter of the unit to ensure clean water quality in the system, in order to avoid impurities in the water affecting the normal operation of the entire equipment and causing equipment damage.

Regularly check the working condition of various components of the unit, inspect the pipeline joints and inflation valves inside the unit for oil stains, and ensure that there is no refrigerant leakage in the unit.

It is recommended to use descaling agents to clean the condenser every year and start the water pump for cleaning3 hours, then rinse 3 times with tap water. Do not use corrosive cleaning solutions to clean the condenser.

Maintain dryness and ventilation

During use, do not stack debris around the unit to avoid blocking the air inlet and outlet. Moreover, it is necessary to keep the surroundings of the unit clean and dry, and avoid prolonged exposure to moisture, as this can cause damage to the components and affect the operation of the unit.

At the same time, it is important to regularly clean the air side heat exchanger,Once every 1-2 months to avoid prolonged use and blockage, which may lead to a decrease in the performance of the air energy heat exchanger and affect the heat transfer efficiency during daily use.
