What is the difference between carbon dioxide heat pumps and existing air source heat pumps?

Carbon dioxide is a common compound in the air. The chemical formula for carbon and oxygen is CO2. A carbon dioxide molecule is made up of two oxygen atoms and one carbon atom through a covalent bond. ambient temperature. Density It is greater than air, soluble in water, reacts with water to form carbonic acid and does not support combustion. Solid carbon dioxide is commonly called dry ice after compression. Carbon dioxide is considered the main source of exacerbation of the greenhouse effect. Industrially, it can be produced by breaking down calcium carbonate under high heat.

Air-energy (source) heat pump, as a type of heat pump technology, has the reputation of "carrying natural energy". It has many advantages such as low cost, easy operation, good heating effect, safety and cleanliness. Usingthe omnipresent energy in the air as the main energy, a small amount of electrical energy is used to drive the compressor to achieve energy transfer. There is no need for complicated setups, expensive water intake, recharge or soil heat exchange systems and a dedicated machine. rooms, which can gradually reduce traditional heating, bring a large amount of polluting emissions to the atmospheric environment. It is necessary to ensure the heating effect while considering the purpose of energy saving and environmental protection.

In addition, air-to-energy (source) heat pumps also have the following characteristics:

Wide range of uses, worry-free in all seasons

>Air energy (source) heat pumps both It can heat in winter and cool in summer, and can meet the needs of winter seasonsand summer. However, other heating equipment can only provide heating in winter, and air conditioning equipment must be installed for cooling. in summer.

Safe operation, environmental protection

Air-energy heat pump (source) adopts heat pump heating form, water and electricity are completely separated and no coal or natural gas is required. , it can therefore achieve complete heating all year round. It works safely 24 hours a day and will not cause pollution to the environment.

Flexible use and no restrictions

Compared to solar, gas, water and ground energy heat pumps (source), air energy heat pumps (source) are not affected by night, clouds, or rainy days. It is not affected by extreme weather conditions such as snow or snow, nor limited by geology or apprgas viewing.

Energy-saving technology, energy-saving and worry-free

The air-to-energy heat pump (source) uses 1 part of the electrical energy and obtains in at the same time more than 2 parts of the free air energy (source) of the outside air, which can produce more than 3 parts of heat energy, is efficient and environmentally friendly, and saves 75% of the monthly electricity bill compared to electric heating. It allows users to save a considerable amount of money. of the electricity bill so that the cost of the machine can be recovered quickly.

In addition to various advantages such as flexibility, energy saving and energy saving, air-to-energy (source) heat pumps also have some limiting factors, such as heat pump problems. environmental adaptability.

The energy source of air-to-energy heat pumps (source) is thermal energyair mic. However, in the extremely cold climate, especially in northern China, there is less heat energy in the air, and the climate is extremely cold. the thermal energy that can be converted is limited. The operating efficiency of ordinary air-to-energy (source) heat pumps will be significantly reduced in extremely low temperature environments of -10°C or lower, affecting the overall operation of the unit and unable to guarantee heating or cooling. hot water supply. Therefore, in order to overcome the technical problems of ordinary air-energy (source) heat pumps which are limited by climatic conditions during winter heating, technologies with strong heating effects have emerged, such as powerful heating technology. Emerson Copeland's vortex?

The methods are as follows:

1. Wear clothing and hats

In thes places with low temperatures, especially in the north, the temperature reaches Water begins to freeze at zero degrees Celsius, so water pipes and other equipment using water should be wrapped with a layer of cloth in cotton and linen, plastic, foam and other objects for insulation. This can be done during. home decoration to beautifully wrap the water pipes Some thoughtful homeowners also make graffiti on the indoor water pipes, which can not only beautify the indoor visual effect, but also take anti-freeze measures for the water pipes water.

2. Raise the indoor temperature

During colder winters, the indoor temperature is also relatively low if the balcony, kitchen, bathroom and all north-facing doors and windows are not. closed tightly at night, indoors The temperature will be even lower and evenme interior water pipes will freeze. Therefore, when decorating your house, you should think about how to increase the indoor temperature in winter. For example, thicker curtains facing north can insulate the room to some extent. When it is cold, doors and windows should be closed and curtains drawn at night.

3. Antifreeze by water drops

Generally speaking, if the water continues to flow, it is more difficult to freeze, so a small solution is to open the tap slightly at night. to let the water continue to flow. This will not freeze water pipes. Although this method can prevent water pipes from freezing, it has the disadvantage of wasting water.

4. Drain the remaining water from the water pipes

Considering the waste caused by the above method, I will suggest another method, which is to drain the water valve. at home before youus go to bed at night when it's cold in winter. Pull it down, then turn on the faucet to empty the water into the water line. This way, if there is no water in the water line, it won't do this. freeze. However, the water door area must be kept warm to prevent the water door from being frozen and unable to be opened the next day.

5. Heat transfer from water pipes

A commonly used method in solar water heaters is electrical tracing and insulation bags. This method can also be used for insulation and heating of water pipes. , but the price is a bit expensive, so those with good financial conditions can try it.

Detailed information:

The drain valve is a pipeline draining device. People understand and. accept that it is mainly used in solar water heaters and its functionwe are to solve the problem of freezing and blocked water pipes due to cold weather. Drain valves can be divided into: solar pipeline drain valves, solar water heater drain valves, steam drain valves, manual drain valves, automatic drain valves, etc.

Function of the drain valve

1. Pipeline Antifreeze: This product may be manual. or automatic draining of water from the water pipe. Since there is no water accumulated in the pipe, the goal of waterless antifreeze is achieved. It can be used to prevent freezing of solar water pipes and tap water supplies.

2. The water is hot when it comes out: because there is no water in the water pipes, so As an application of solar energy, it changes the past history of putting d First cold water, then hot water, and the hot water flows directly into it.rs the bottom. As an antifreeze for tap water, it changes the freezing situation of outdoor taps. You can use tap water easily and worry-free all year round.
