What is the working principle of a hot water heat pump?

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.

What conditions should a hot water heat pump have in its application?

(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.

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?

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.

What is the working principle of the air source heat pump hot water (heater) unit?

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.

Air source heat pump hot water (heater) unit needs electricity, will the operating cost be high?

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.

Swimming pools lose energy in a variety of ways, but evaporation is by far the largest source of energy loss. Evaporating water requires tremendous amounts of energy, how to choose a best solution to heat a swimming pool to keep the water temperature to be stable at 26 to 27℃？The solar energy, gas energy and electricity energy are the solutions we adopt in common.

ANALYSIS ON DIFFERENT ENERGY

Above comparison shows the advantage to adopt renewable energy of Solar water heating system and air source heat pump, but it also depends on the different application.

For example, if use solar water heating system to heat a swimming pool, it needs a lot of space to install big area solar collectors.

Meanwhile ,if use swimming pool air source heat pump, the installation can be easier.

How can a heat pump save so much energy?

Normally we use COP as a core value on a air source heat pump.

COP means Coefficient Of Performance.

From the technical data we can see that the COP is almost based on formula of:

COP = heat capacity ( Power output) / Power input

Question one:

Why 1kwh electricity POWER INPUT can get many times POWER OUTPUT to heat the water？

Answer One：

1kwh electricity power input mostly consumed by the heat pump compressor, which compress the Refrigerant R32/R410a between Vapour & Liquid form to absorb plenty heat from Air and release to heat the water, see the attached diagram.

Question Two:

Normally a heat pump can get a COP between 4 to 7, why a heat pump with an inverter can get a COP up to 13 in summer time?

Answer Two：

DC Inverter Pool Heat Pumps technology uses the reverse Carnot cycle principle to drive heat from a low-level heat source to a high-level heat source under the promotion of high-level energy, that is, to convert a heat source that cannot be directly used into an available high-grade heat source, thereby achieving partial savings. Disposable high-energy technology. The DC inverter pool heat pumps exchanges heat with the pool water through the continuous circulation of the refrigerant to heat the water.

How to select a right model swimming pool collector?

The target temperature of a swimming pool is normally at 26 to 27℃, so the heat loss is calculated based on compensate the heat loss to keep the temperature.

Formula for heat loss calculation:
