Heat pump water heatersare "heat transfer" devices that use the principle of refrigeration to absorb heat from the air to heat water. A refrigerant with a boiling point of more than minus 10°C is passed into the exchanger, and the refrigerant absorbs heat from the air by evaporating from liquid to gas.
What is the safety of the use of heat pump water heaters?
What is the output of the heat pump water heater?
Where is the convenience of heat pump water heater?
The heat pump water heater does not require sunlight, so it can be placed at home or outdoors. After the water stored in the solar water heater is used up, it is difficult to produce hot water immediately. If the electric heating takes a long time, as long as there is air and the temperature is above minus 20 degrees Celsius, the heat pump water heater can be under pressure 24 hours a day. run. In this way, even if one tank of water is used up, the air source water heater will produce another tank of hot water in about an hour or even less time. At the same time, the heat pump water heater can also fundamentally eliminate the safety hazards such as electric water heater leakage, dry burning and harmful gas generated when the gas water heater is used.
The water output is large. The water tank capacity of the heat pump water heater is between 150L-760L. Users can choose the corresponding capacity of the air energy water heater according to the needs of the family. Water, bath water, etc., truly realize the central hot water for the whole family and improve the quality of life of users. But be aware that heating at extremely low temperatures with a heat pump water heater is more difficult and may waste electricity, and the water tank needs to take up the heating space.
Long life
The life of heat pump water heater is generally 10 years (here for reference), which is longer than 6 years for gas water heaters and 8 years for electric water heaters. The advantages of air source water heater life can reduce the frequency of replacement water heaters, the trouble of installation, and save a lot of money.
Central hot water
Consumers often need hot water in their daily lives, but without hot water sources, they usually boil a pot of water for use. The heat pump water heater has a central hot water function. It stores the heated water in the heat preservation water tank, and there is a comfortable and constant temperature hot water as long as you press the tap. The hot water of the air energy water heater can be used in the whole family, fully meeting the domestic hot water demand of consumers.

What are the environmental protection features of heat pump water heaters?
How does the heat pump water heater work?
Environmental protection, the heat pump water heater realizes that there is hot water whenever you want. Because it does not use electric heating elements for direct heating, compared with electric water heaters, it eliminates the potential safety hazard of electric leakage; compared with gas water heaters, there is no gas leakage, or Safety hazards such as carbon monoxide poisoning, so it has better safety performance. The air energy heat pump is regenerative, and the heating function is automatically activated according to the temperature in the water tank to ensure sufficient supply of hot water for 24 hours, so there is no such problem as the gas water heater that cannot meet the hot water for multiple faucets at the same time, nor will it There is a problem that the capacity of the electric water heater is small, and many people need to wait for a bath. The hot water is ready to use, the water output is large, and the water temperature is stable, meeting all your expectations for hot water. Because its power consumption is only one-fourth of the same amount of electric water heater, which is equivalent to using the same amount of hot water, using an air-energy heat pump, the electricity bill is only one-fourth of that of electric heating. Calculated for a family of 4, the normal consumption of hot water is about 200l/day. Electric water heaters cost about 4 yuan/day for heating, while heat pump water heaters only cost about 1 yuan/day, saving 1,000 yuan a year.
Environmental protection of heat pump water heaters: using clean energy, no waste gas, waste water, waste residue, and no thermal effect on the air. The use of environmentally friendly heat medium, cfc-free, will not cause damage to the atmospheric ozone layer. Uses of heat pump water heaters: heat pump water heaters can be used in hot water systems with a temperature requirement lower than 65°C, such as bathing, sauna, swimming pool, foot bath, beauty salon, agricultural breeding, etc. The heat pump water heater has a high energy efficiency ratio and is more energy-saving.
A heat pump water heater is essentially a heat lifting device. The function of the heat pump is to absorb heat from the surrounding environment and transfer it to the object being heated (a higher temperature object). Its working principle is the same as that of a refrigerator. It works according to the reversed Carnot cycle, the only difference is that the working temperature range is different.

How does the heat pump water heater achieve the effect of saving energy?
What should we pay attention to when using heat pump water heater?
What are the operational advantages of heat pump water heaters?
When the heat pump water heater is working, the energy QA stored in the ambient medium is absorbed in the evaporator; it consumes a part of the energy itself, that is, the compressor consumes power QB; the heat release QC is carried out in the condenser through the working fluid circulation system, QC=QA+QB, it can be seen that the energy output by the heat pump is the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; therefore, the use of heat pump technology can save a lot of electric energy.
temperature, water consumption
Put the bath water in the heat pump water heater. The most suitable water temperature is 42°C. It can be slightly higher by 1-2°C for middle-aged and elderly people. The water for showering is about 40~50 liters per person. Bathtubs and Jacuzzis are determined by capacity.
How much hot water can be made
In terms of product performance and theory, the heat pump water heater can be cycled back and forth to continuously produce hot water. Under normal temperature, the hot water can be produced per hour as follows (45℃-55℃): It depends on the size of the unit.
The heat pump water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to heat up and pressurize it. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of the electric water heater. Its annual average thermal efficiency ratio is 4 times that of the electric heating, and the energy efficiency is high.
The heat pump water heater overcomes the shortcomings of solar water heaters that rely on sunlight for heating and inconvenient installation. Since the work of the air energy water heater is to exchange heat through the medium, it does not need the electric heating element to be in direct contact with the water, which avoids the danger of electric water heater leakage, and also prevents the gas water heater from the danger of explosion and poisoning, and more effectively controls the gas Air Pollution Caused by Exhaust Gases from Water Heaters.

The demand for Swimming Pool Heat Pump is also growing. Guangdong JNOD New Energy Technology Co., LTD. has been committed to providing customers with the best quality Swimming Pool Heat Pump for many years.
The heating and cooling heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source, and is also a new energy technology that has attracted a lot of attention worldwide. It differs from the well-known mechanical equipment, which can increase the potential energy"Pumps"; A heat pump usually first extracts inferior heat energy from natural air, water or earth, then performs work by electricity, and then provides people with available energy that can be used. of high quality thermal energy.
What is the working medium of the heating and cooling heat pump?
What role does the heating and cooling heat pump play?
What do you know about heating and cooling heat pumps?
The working medium of the heating and cooling heat pump used to be Freon, but since Freon adversely affects the Earth's atmospheric ozone to protect the Earth's ecological environment, in addition to improving the cooling coefficient of the heat pump and effective use, science is also committed to new technologies in various countries. With the development of quality, the working fluid was used as a replacement for Freon. However, the work equipment of most Chinese manufacturers today is still R22, and the era of using environmentally friendly work equipment R417A and 134A has not yet arrived. Some countries, such as Japan, have taken the lead in using CO2 as a working medium to avoid damaging the ozone layer. (Therefore, the copper pipes must be firmly connected during installation to prevent R22 from leaking.) In addition, the above R22, R417A, 134A and CO2 do not harm the human body. Even if there is a leak, all the equipment is still safe.
The low temperature heat sources normally used in heat pumps for heating and cooling are the media around us. Air, river water, seawater, municipal wastewater, surface water, groundwater, treated water, fire pits or working fluids, which are discharged from industrial production plants these working fluids often have similar temperatures to the surrounding medium. The operating principle of the heating and cooling heat pump is the same as that of the compression chiller. In order to fully exploit its efficiency, the small air conditioner is cooled with the same equipment in summer or heated in winter. When heating in winter, the evaporator and condenser in the air conditioning system are exchanged via a switching valve.
Heat pumps for heating and cooling are an intelligent, efficient and versatile solution for year-round heating, cooling and hot water supply solutions. In addition to their flexibility and wide application, they are energy efficient and environmentally friendly, with advanced EVI technology and green refrigerant R32/R410A. So you can enjoy a comfortable home and save energy at the same time.
JNOD insisted on developing with technological innovation, it had several nationally famous technicians and had invented several product patents. The company has strictly implemented the international ISO quality management system, and the products are of reliable guaranteed quality.
JNOD are selling R32 inverter swimming pool heat pump, its heating capacity ranges from 5.5-32Kw. So, it will be a problem for user or wholesaler to choose the suitable heating capacity for different pool sizes. Let us show you 2 methods to choose the suitable.
If you do not want to do complicated calculations and do not take into account extreme weather, you can use the following formula: 3KW for 10m³. For example, if you want to heat a 30CBM pool, (30 CBM÷10CBM)* 3KW = 9KW . So, you can choose the 9.5Kw model.
This method is used to do a very precise calculation on the heating capacity, considering the heating time, water temperature, ambient temperature, etc.
* Step 1: Calculate the needed heating capacity
In the calculation, we usually set the outlet water temperature at 28℃, primary heating time usually is 48hours.
Formula will use: Q=1.163*△t*V ;
W=Q/T
Explanation: Q = Heat Demand (KwH)
△t = Temperature Difference (℃)
V = volume of pool (m³)
W = Heat pump capacity(Kw) - usually will add 15-25% of heat loss
T = Hours for heating (H)
Example: A swimming pool 10*4*1.5m, original temperature is 18℃
Answer: set the target temperature into 28℃, heating hour into 48 hours
Q = 1.163*(28-18)*(10*4*1.5)=697.8 KwH
W= (1+15%) *Q/T=1.15*697.8/48=16.72 KW
*Step 2 : Choose the suitable heating capacity depending on working condition
The heating capacity of a heat pump is not constant; it changes with the ambient temperature. Therefore, after calculating the required heating capacity, we also need to choose the model we need according to the ambient temperature.
Still that sample, we calculate that 16.72Kw is needed. If the ambient temperature is around 24-27℃, you can choose the 17.5Kw model; if ambient temp is around 12-15℃, better to choose 25kw model.
