Air source heat pump water heater units and solar water heaters, as necessities of residents' lives, are both devices that use natural and environmentally friendly energy to generate hot water, but they have essential differences. The air source heat pump water heater unit uses air heat as its energy source, but the way it obtains energy is active, so it is not affected by cloudy, rainy, days and nights. The way solar water heaters obtain energy is passive. It relies on direct sunlight to have a better effect, so it can only produce hot water on sunny days.

What kind of device is an air source heat pump hot water (heater) unit?
What is the working principle of the air source heat pump hot water (heater) unit?
Air source heat pump hot water (heater) unit needs electricity, will the operating cost be high?
This equipment of air source heat pump water is high-tech energy-saving equipment for the production of hot water. It absorbs heat from the air to heat water to 65°C (low-end manufacturers heat it to 55°C). As central hot water equipment, drawing on the principle of an all-in-one heat pump, it is widely used in collective water supply units such as hotels, sauna centers, hospitals, factories, and residential communities, as well as small water supply units such as villas, residences and beauty salons.
The air source heat pump hot water (heater) unit consists of a compressor-condenser-throttle-evaporator-compression mechanism into a circulating system. The heat medium (also called refrigerant) circulates in the system under the action of the heat pump. The air source heat pump completes the gaseous pressure increase and temperature rise process in the compressor (the temperature is as high as 80-100 ℃). After it enters the condenser, it releases high-temperature heat to heat the water, and at the same time, it is cooled and transformed into a liquid state. When it runs to the evaporator, The liquid quickly absorbs heat and evaporates and transforms into a gaseous state again, and at the same time the temperature drops to minus 20 ℃-30 ℃, then the air around the evaporator will continuously transfer low-temperature heat to the heat medium. The continuous circulation of the heat medium realizes the process of converting the low-temperature heat in the air into high-temperature heat and heating the cold water.
The air source heat pump water heater (heater) unit is different from an electric water heater (heater) unit. The electric water heater (heater) unit uses the electric heating tube to directly convert electrical energy into heat to heat cold water. The highest conversion efficiency of electricity to heat is about 95℅. However, the electric energy consumed by the air source heat pump water heater (heater) unit drives the air source heat pump to work and only plays a role in promoting the circulation of the heat medium. Because a large amount of heat in the air enters the system, the energy obtained by the hot water is much greater than that consumed by the heat pump. For electric energy, the ratio of these two energies can reach more than 3-4 times, that is, the conversion rate of electricity to heat is as high as 400℅. That is to say: the main energy for heating water in the air-source heat pump water heater (heater) unit system is the surrounding air, and enough electricity can be obtained by using 1/3 or 1/4 of the electricity consumed by the electric water heater (heater) unit. For hot water, the operating cost is obviously much lower than that of electric water heaters or electric boilers.
It is the responsibility of each manufacturer to produce an air source heat pump that meets the standards, so as to ensure the safety of the electricity supply. MICOE conducts many tests on durable air source heat pumps before they leave the factory, and the quality qualification rate is guaranteed. If you are in the air source heat pump business, you can consider our cost-effective products.
The hot water heat pump is one of the most widely used forms of heat pumps in my country. Water is used as a source of cold and heat for heating in winter and cooling in summer. Do you know what conditions hot water heat pumps should meet when they are used?
Here is the content list:
1. What is the working principle of a hot water heat pump?
2.What conditions should a hot water heat pump have in its application?
(1) Reliable water source
(2) Sufficient water
(3) Water temperature
The working principle of the hot water heat pump heating in winter: the hot water heat pump takes the groundwater from the water extraction well and sends it to the hot water heat pump unit. The unit absorbs the low-grade groundwater of heat energy, and then it is sent back to the ground and the earth to heat again after being charged well. Exchange to increase heat energy, and then reuse.
The liquid refrigerant in the hot water heat pump unit absorbs the low-level heat energy of the groundwater in the evaporator and evaporates into a low-temperature and low-pressure gaseous refrigerant. The compressor (using a fully enclosed flexible scroll compressor with reliable operation and high heating efficiency) compresses it into a high temperature and high-pressure gaseous refrigerant, and then sends it out of the condenser. The high-temperature and high-pressure gaseous refrigerant in the condenser transfer heat to the building's circulating water (geothermal or heating radiator) through heat exchange. After dissipating the heat to the building, it condenses into a liquid state and then returns to the hot water heat pump evaporator to repeat.
(1) Reliable water source
Just listen to the name of the hot water heat pump to know how important the water source is. A reliable water source is the first requirement in the application. The water source can be surface water, rivers, lakes, and groundwater. Groundwater is widely used. As groundwater is one of the country's important resources, the government has restrictions and regulations on the exploitation and use of it. Therefore, before installing a hot water heat pump, it must first be checked by relevant government departments.
(2) Sufficient water
The amount of water can be related to the cooling or heating efficiency of the hot water heat pump, so before determining the plan, the amount of water should be determined, and pumping experiments should be carried out when necessary to see if the groundwater level drop during the continuous pumping time meets the requirements.
(3) Water temperature
The temperature of the water source is also an important factor affecting the hot water heat pump. The same unit provides different cold and heat due to different water temperatures. Generally speaking, the range of hot water heat pump requirements for water source temperature is: under cooling conditions, the water temperature into the evaporator is 10-22°C; under heating conditions, the water temperature into the condenser is 18-40°C.
It is the responsibility of each manufacturer to produce hot water heat pumps that meet the standards, to ensure the healthy development of the hot water heat pumps market. MICOE conducts many tests on hot water heat pumps before they leave the factory, and the quality qualification rate is guaranteed. If you are in the hot water heat pumps business, you can consider our cost-effective products.
