Factory supplies construction site with 15-horsepower water circulation air-source hot water heaters

Operating Principle

A complete integrated air-source heat pump water heater consists of two main parts:

Manufacture the cooling section and the heating hot water section. However, these two sections are closely interconnected, inseparable, and must operate simultaneously. This means cooling the kitchen while heating the hot water, or vice versa, heating the hot water while cooling the kitchen.

The internal structure is primarily composed of four core components: the compressor, condenser, expansion valve, and evaporator.

The operation process is as follows: The compressor compresses the low-pressure refrigerant that returns, transforming it into a high-temperature, high-pressure gas that is then discharged. This high-temperature, high-pressure refrigerant gas flows through copper pipes wrapped around the outside of the water tank, with the heat transferred through the pipes into the tank. As the refrigerant cools, it turns into a liquid under continuous pressure, then passes through an expansion valve into the evaporator. Due to the sudden drop in pressure in the evaporator, the liquid refrigerant rapidly evaporates into a gas, absorbing a large amount of heat. At the same time, driven by the fan, a large volume of air flows over the exterior surface of the evaporator, with the evaporator absorbing the energy from the air, causing the air temperature to drop rapidly and become cold air that is exhausted into the kitchen. The refrigerant, having absorbed a certain amount of energy, then returns to the compressor to start the cycle anew.

The working principle of the integrated air-source heat pump water heater, as can be seen from the above, is somewhat similar to that of air conditioners. It applies the reverse Carnot principle, absorbing a large amount of low-temperature heat energy from the air, compressing it into high-temperature heat energy by the compressor, and then transferring it to the water tank to heat the water. The entire process is a heat transfer process (from the air to the water), not a conversion process. It does not heat the water using electric heating elements or by burning combustible gases.

Air Source Heat Pump Technology

A heat pump water heater is a new type of hot water and heating pump product that can replace boiler-based heating equipment and hot water systems. Compared to traditional solar panels, heat pump water heaters can absorb not only air heat but also solar energy. By absorbing heat through a refrigerant's temperature difference and then heating through compression by the compressor, heat pump water heaters exchange heat with water, significantly improving thermal efficiency. They make full use of new energy sources, combining the respective advantages of electric water heaters and solar water heaters.An integrated new type of water heater. Currently, there are three types of heat pump water heaters: air-source, water-source, and solar-powered, which are among the equipment for exploring and utilizing new energy sources.

Air-source heat pumps are one of the products in today's world, utilizing refrigerant as a medium. The refrigerant absorbs energy from the air in the fan coil, then, after being compressed by the compressor to generate heat, transfers the heat to water through an exchanger to produce hot water. The hot water is circulated through a system to the user's radiators for heating or used directly for hot water supply.

Development of Air Source Heat Pumps

Air-source heat pump technology, since its invention in 1924, was not fully recognized and utilized by humans for a long time. Heating was still primarily achieved through traditional methods like gas or electric heating, as they were simpler and more direct. However, it wasn't until the 1960s, following the global energy crisis, that it gained adequate attention. With the continuous development of the global economy, it's crucial to leave energy and power resources for future generations, which necessitates the conservation and rational use of energy. As a result, countries around the world have increased their research and development efforts, promoting the adoption of heat pump technology, making it widely used today.

2. Low operational costs: Compared to oil and gas boilers, it can save up to 70% of energy annually on average. With the decreasing electricity prices and rising fuel costs, the advantage of low operational costs becomes more pronounced.

3. Environmental Protection: Heat pump products emit no combustion by-products, and environmentally friendly refrigerants are used.

4. Safe Operation, Unattended: Compared to fuel boilers, it operates safely and is fully automatic, requiring no on-site staff.

Advantages of Heat Pumps over Solar Products

Wide application range; products are suitable for temperatures between -10℃ and 40℃; can be used throughout the year without being affected by bad weather such as rain, snow, or winter nights.

2. The heat pump products can continuously heat water, providing a continuous supply of hot water, unlike traditional solar water heaters, which meet the user's needs.

3. Low operating costs: While operating costs are higher than conventional solar panels during spring, summer, autumn, and winter with good sunlight, they significantly surpass solar panels' electric auxiliary heating in cloudy, rainy, and nighttime conditions.

The Difference Between Heat Pump Products and Solar Products

In terms of working principle, this product does not belong to traditional solar energy products. Heat pump products are significantly different from conventional solar products. Common solar products use water as the medium and require direct sunlight or radiation to achieve heating effects. In contrast, this product absorbs heat energy from the air and solar radiation using refrigerant, heats it up by compressing it through a compressor, and then exchanges heat with water to achieve heating. Therefore, the product operates on the same principle as air conditioning.

Air-source Heat Pump Water HeaterSix Major Advantages:

1）Safety

It eliminates the risk of electric shock, as it does not use electric heating elements for direct heating, making it safer than electric water heaters. Additionally, there's no risk of gas leakage or poisoning, unlike gas water heaters, thus offering enhanced safety performance.

2）Cozy

The integrated air-source heat pump water heater is a storage type, with the heating function automatically activated based on the temperature inside the tank, ensuring a constant supply of hot water 24/7. This eliminates the issue of not being able to meet multiple hot water demands simultaneously, as with gas water heaters, and also avoids the problem of limited capacity in electric water heaters, where multiple people have to wait for their turn to shower. It provides instant hot water on demand, with a large water flow and stable temperature, meeting all your expectations for hot water.

3）Save money

Due to its electricity consumption being only one-fourth that of an equivalent electric water heater, using a full-air energy water heater requires only one-fourth the electricity for the same amount of hot water. For a family of four, with an average daily hot water usage of around 200L, using an electric water heater would cost about 4 yuan per day, whereas a full-air energy water heater would only cost about 1 yuan per day, saving approximately 1,000 yuan in electricity bills annually.

4）Kitchen Refrigeration

This is a significant advantage; regular water heaters (such as electric, gas, and solar water heaters, etc.) do not have refrigeration capabilities. If additional refrigeration is needed in the kitchen, a kitchen air conditioner must be purchased. Since the kitchen is a special environment with oil and smoke, the kitchen air conditioner is different from a standard one, and it's also much more expensive (usually over 4,000 yuan).

5）Green and eco-friendly

A heat pump is a mechanical device that utilizes artificial technology to convert low-temperature thermal energy into high-temperature thermal energy, thereby achieving heating effects. It absorbs thermal energy from a low-temperature heat source (such as natural air around the environment, groundwater, river water, seawater, wastewater, etc.) and has almost no impact on the environment, making it a genuinely eco-friendly water heater.

6）Low-carbon Fashion

In today's era where energy conservation and carbon reduction are the trend, a lifestyle that saves energy and cuts down on carbon emissions is essential. As previously mentioned, the integrated air-source heat pump water heater operates on the reverse Carnot principle, transferring energy from the air to the water. It does not directly heat water with electrical heating elements, thus achieving an energy efficiency four times that of electric water heaters. This means that to heat an equivalent amount of water, the electricity consumption is only a quarter of that of electric water heaters, significantly reducing power consumption. In China, 70% of electricity is generated by burning coal in power plants, so saving electricity also means reducing carbon emissions.

Regular maintenance checks

Any issue with a component of a device can affect its normal operation.

Regularly inspect the electrical connections of the air-source heat pump water heater's power and electrical system for tightness and any abnormal operation of electrical components. In case of anomalies, timely repair and replacement are required. Check if the pump and waterway valves are functioning properly, and if there are any leaks in the piping system and pipe joints.

Additionally, regular checks of the water system's补水, safety valves, level controllers, and exhaust devices should be conducted to ensure proper operation, preventing air from entering the system and reducing the circulation volume of water, which could affect the heat output of the unit and the reliability of its operation.

During operation and maintenance, all safety protection devices and system settings within the unit should remain at the factory settings; do not adjust them manually.

Regular system cleaning

During operation, we should regularly clean the waterway filter of the unit to ensure the water quality within the system remains clean, thereby avoiding impurities in the water from affecting the normal operation of the entire equipment, which could lead to equipment damage.

Regularly inspect the operating status of the unit's components, check for oil stains on the internal piping joints and inflation valves, and ensure there are no leaks in the refrigerant.

It is recommended to clean the condenser with a descaling agent annually, operate the pump for 3 hours, and then rinse with tap water 3 times. Corrosive cleaning fluids are prohibited for cleaning the condenser.

Maintain dry and well-ventilated

During use, do not pile杂物 around the equipment to prevent blocking the inlets and outlets. Moreover, ensure the area around the unit is kept clean and dry; avoid prolonged moisture, as it can damage components and affect the unit's operation.

Also, be sure to clean the air-side heat exchanger regularly, every 1-2 months, to prevent long-term use from causing blockages and reducing the heat exchanger's performance of the air-source heat pump, which may affect its heat exchange efficiency during daily use.
