How does the Heating and Cooling Heat Pump perform cooling and heating respectively?

When the air conditioner cools down in summer, the Heating and Cooling Heat Pump operates according to the cooling condition, and the high-pressure steam discharged from the compressor enters the condenser through the reversing valve (also known as the four-way valve); when heating in winter, the reversing valve Turn to the working position of the heat pump, so the high-pressure refrigerant vapor discharged from the compressor flows into the indoor evaporator (used as a condenser) after passing through the reversing valve, and the latent heat released when the refrigerant vapor condenses heats the indoor air to achieve indoor heating purposes. The condensed liquid refrigerant flows in the reverse direction through the throttling device into the condenser (used as an evaporator), absorbs external heat and evaporates, and the evaporated steam is sucked by the compressor after passing through the reversing valve to complete the heating cycle. In this way, the Heating and Cooling Heat Pump "pumps" the heat from the outside air (or circulating water) into the room with a higher temperature, so it is called a "heat pump"

What is the principle of Heating and Cooling Heat Pump?

When the air conditioner cools down in summer, it operates according to the refrigeration condition. The high-pressure steam discharged from the compressor by the Heating and Cooling Heat Pump enters the condenser through the reversing valve (also known as the four-way valve), and the refrigerant vapor is condensed into liquid. The flow device enters the evaporator, absorbs heat in the evaporator, cools the indoor air, and the evaporated refrigerant vapor is sucked by the compressor after passing through the reversing valve, and this cycle is repeated to realize the refrigeration cycle.

Why is Heating and Cooling Heat Pump so practical?

Heating and Cooling Heat Pump can operate normally between -27℃-48℃, and some low-temperature air-energy heat pumps are also capable of -35℃ ambient temperature, and still maintain normal operation. In our environment, a It can be used all-weather all year round, and will not be affected too much by rainy, windy and snowy weather, nor will it be affected by low temperature at night. However, solar heating equipment is greatly affected by environmental factors. In the case of insufficient light, it is difficult to achieve the effect of indoor heating, especially in areas with low ambient temperature in winter.

Air source heat pumps are a relatively new technology that can be used to heat your property in a more environmentally friendly and energy efficient way. As they use the ambient air outside of the property as their heat source, there is no need for a gas supply. This makes them a suitable heating solution for most homes, regardless of whether they are connected to the gas network.

How does an air source heat pump work?

There are 2 types of air source heat pump: air to water and air to air. This is how each of them works.

How an air to water heat pump works

Here is a step by step breakdown of how an air to water heat pump works:

1.    The heat pump has an outdoor unit, which contains a fan that draws air in from outside the property. This air then passes over tubes or coils filled with liquid refrigerant.

2.    The liquid refrigerant is much colder than the ambient temperature, even if the outside air is at sub-zero temperatures, and begins to heat up when air is passed over it.

3.    As the refrigerant continues to heat up, it becomes steam which is moved to a compressor. This compresses the steam which raises the temperature of the refrigerant even further.

4.    The heat of the refrigerant is then transferred to the water in the central heating system in your home, and any water stored in a hot water tank, for hot running water.

5.    The refrigerant, which has now passed on its heat, is then cooled and cycled back to begin the process again.

How an air to water heat pump works

Air to air heat pumps are essentially updated versions of air conditioning units that don't only cool air, but can also heat it. They work in the same way as an air to water heat pump, but transfer heat to the air in a ventilation system, rather than to the water in a central heating system.
A big drawback of air to air heat pumps is that they require a property to have air ducts installed throughout, in which to distribute warm air. They are also incapable of heating running water. This means they are not generally suitable for existing and older properties.

We have provided an in depth comparison of these heat pumps in our Air to Water Heat Pumps vs Air to Air Heat Pumps article.

Different types of air source heat pump

Not only are there air to water and air to air heat pumps, but each of these types of air source heat pump is generally available in different models. Namely monobloc air source heat pumps and split air source heat pumps.

Monobloc heat pumps

These are a large single outdoor fan unit which connects directly to the central heating system and will need to be located close to your property. There is no indoor unit, which can help to free-up space inside your property.

Split heat pumps

Split heat pumps consist of 2 main units: the outdoor fan unit and the indoor heating and cooling unit. These generally take up less space outside, but will require the use of some inside space.

To understand the pros and cons of monobloc and split air source heat pumps, and to find out more about how they differ, you can go to our article: Split Heat Pumps vs Monobloc Heat Pumps

Air source heat pump temperatures

Air to water heat pumps often come in 2 separate temperature ranges: low temperature and high temperature. It's important to know what each of these temperature types are as they could affect your installation costs.

Low temperature heat pumps

While traditional gas boilers will heat the water in a central heating system to temperatures of around 80°C to ensure the radiators around the property are providing ample heat. Low temperature air source heat pumps are only capable of heating radiators to a temperature of around 60°C. Due to the lower maximum temperature these heat pumps are capable of producing, more heated surface area is required to keep a property warm. This means you will need bigger radiators or underfloor heating to truly benefit from the installation of a low temperature heat pump.

High temperature heat pumps

Generally, high temperature air source heat pumps are capable of heating the water in a central heating system to around 75°C – 80°C. This is more in line with the temperatures provided by gas boilers. This makes them easier to integrate into an existing traditional heating system, but they do require more power to run.

The benefits & disadvantages of an air source heat pump

There are many benefits to getting an air source heat pump installed at your property, but there are some disadvantages too. To help you make the right decision for your home, we created the article: Air Source Heat Pumps vs Gas Boilers. This covers the advantages and disadvantages of each technology, cost comparisons and things you will need to consider when getting either heating solution installed.

Finding an Installer

As air source heat pumps are a relatively new technology, you may find it harder to find a heating engineer in your area that's well versed with installing them. More and more heating engineers are starting to adopt air source heat pumps as a heating solution they will install, but it may not be clear where to find them.
Fortunately, this is something we can help with. Simply click the link below and we'll find you up to 3 quotes from air source trained heating engineers in your area.

During the working process of the heat pump water heater, it consumes 1-part electricity to get the compressor running, and at the same time, it can absorb about 4-part heat from the ambient air and transfer it to the water. Therefore, air energy water heaters can save almost 3/4 electricity compared to electric water heaters. That is, the electric water heater consumes 4 kWh electricity to produce hot water, and the air energy water heater requires only 1 kWh electricity.

What role does the refrigerant play in the unit composition of the heat pump water heater?

What role does the refrigerant play in the unit composition of the heat pump water heater?

The heat pump unit contains a special heat-absorbing refrigerant. In the liquefied state, the normal temperature is below minus 20°C. Therefore, there is a temperature difference between it and the outside temperature. The refrigerant absorbs the outside temperature and is stored in the evaporator. Generate pressure and evaporate and evaporate, and through the work of the heat exchanger (heat pump), when the refrigerant is transferred from the evaporated state to the liquefied state, the objectively existing heat is released to the storage water in the water tank.

What is the physical principle of how a heat pump water heater works?

The heat pump water heateruses the heat absorbing medium (refrigerant) in the device to collect heat energy from the air or the natural environment, heats the cold water quickly through the heat exchanger and at the same time releases the cold air, avoiding the lack that conventional solar products can not work in rainy weather and at night. As long as the outside temperature is above 1-15 degrees, it can work normally, so can be more efficient and energy-saving, at the same time does not occupy open space, and is easy to install and flexible to use.

What is the significance of the appearance of heat pump water heaters?

With the rapid development of the economy and the improvement of people's living standards, water heating has become a necessity for people's lives. However, conventional electric water heaters have the disadvantages of large energy consumption, high cost and serious environmental pollution; while the operation of energy-saving and environmentally friendly solar water heaters is also restricted due to weather conditions. The heating principle of the air heat pump is different from that of the conventional solar water heater. The air heat pump uses air, water, solar energy, etc. as a low temperature heat source, and the air heat pump uses the electrical energy as energy to absorb heat from the low temperature side to heat the service water.

With the soaring price of gas and the emphasis on environmental protection in many countries around the world, heat pumps are becoming more and more important and popular among consumers and manufacturers. In the last 2 years, many various kinds of heat pumps have appeared on the market. In this article, we will teach you how to choose a good hybrid hot water heat pump, also called all in one heat pump water heater.

For a hot water heat pump, the water tank is very important, both the outcase and the interior are very important.

* Internal

At this point, we would recommend our customers to choose a hot water heat pump with an enameled water tank for the following reasons.

A. Good thermal insulation: Take JNOD's all in one heat pump with enameled tank as an example. After testing, when the water in the tank is boiled to the set temperature and then power off, the water in the tank will only have a temperature drop of 5-8 degrees Celsius after 24 hours. Such a hybrid heat pump is your wise choice.

B. Strong corrosion resistance: In areas with bad water quality, there are more impurities in the water. If you use the general iron water tank, the welding joints inside are prone to chemical reaction with impurities, which leads to the problem of water leakage.

* Outcase

Here we recommend that consumers choose galvanized steel plate as the shell material. There are businesses in the market will choose color plate. The service life of the color plate is very short, only 1-2 years. A long time inside the box exposed will also lead to water leakage problems in the tank.

Expect these suggestions will let you choose a better heat pump! Feel free to contact JNOD with any questions! Link:https://www.jnodheatpump.com

Is there a difference between an air source heat pump water heater and a normal water heater?

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.
