What is COP What does COP mean?

The COP value is defined in more detail in the ARI standard (American Air Conditioning and Refrigeration Association), which means that heating and cooling are defined by different names. When heating, the ratio of heat production to total input power is called the cyclic coefficient of performance of the heat pump, or COP.

In the case of cooling, the ratio of the cooling capacity of the appliance to the total input power is known as the energy efficiency ratio of the heat pump, or EER. In fact, the difference between COP and EER is very small, in order to facilitate the calculation, it is stipulated that the cycle performance coefficient and energy efficiency ratio of electrical heat pumps are uniformly used to perform.

Energy conversion of heat pumps

As a natural phenomenon, just as water flows from high to low, heat always flows from the high to the low temperature. But one can create machines, and just as one uses a pump to lift water from a low place to a high place, a heat pump can draw heat from a low temperature to a high temperature.

Therefore, the heat pump is essentially a heat lifting device, the role of the heat pump is to absorb heat from the surrounding environment, and transfer it to the object to be heated (the object with higher temperature), its working principle is the same as that of the refrigerator, all of which work according to the reverse Carnot cycle, the difference is only that the operating temperature range is different.

The COP value is the ratio of the cooling capacity of the unit to the energy consumption of the unit, including the energy and electricity released from the fuel.

It is the cooling capacity (heating capacity) and the power consumed.

Often used in the refrigeration industry, it is the acronym of coefficient of performance, which is called performance coefficient in Chinese, defined as.

COP = Cooling capacity (or heating capacity) The amount of energy (which can be electricity, heat, or fuel) consumed

Energy efficiency ratio. Under a certain working condition, the ratio of the refrigeration gauge of the refrigeration compressor to the refrigeration compressor shaft power PE under the same working condition.

The COP value refers to the abbreviation of the "coefficient of performance" of the air conditioner, also known as the heat pump coefficient. It is an important parameter to measure the cooling and heating efficiency of thermal energy equipment such as air conditioners and heat pumps, and refers to the ratio of output power (cooling capacity or heating capacity) to input power (electrical energy or other energy consumed). Specifically, the higher the COP value, the more energy efficient the equipment is to provide more cooling or heating while consuming the same amount of energy.

Normally, the COP value of an air conditioner will vary according to different ambient temperatures, because the cooling or heating effect of an air conditioner is related to the difference in outdoor temperature. Therefore, the COP value is usually provided with a guideline value in the instruction manual of the air conditioner, which is usually an average value obtained under specific environmental conditions and is for the user's reference only.

The energy efficiency ratio is the ratio of energy conversion efficiency. The greater the energy efficiency ratio, the more electricity is saved. In addition to refrigeration and noise reduction, in today's increasingly pursuit of environmental protection and energy saving, the amount of electricity used is also a concern for everyone.

For consumers, choosing energy-saving air conditioners can save the electricity bill in the future use, which is undoubtedly a smart choice. Energy efficiency ratio and frequency conversion. The energy efficiency ratio refers to the ratio of the cooling capacity to the effective input power of the air conditioner during refrigeration operation.

The value of the energy efficiency ratio reflects the cooling capacity of the air conditioner product when every 1000W of electrical power consumed is fast.

The magnitude of the energy efficiency ratio value reflects the energy savings of different air conditioner products. The higher the energy efficiency ratio, the higher the energy conversion efficiency of the product, and the less electricity the air conditioner consumes per unit time.

The energy efficiency label of Ling Changtong on the air conditioner allows you to easily "recognize" the energy-saving "star" from many air conditioners, as long as you look at the product grade marked on the right side of the logo, you can make a judgment: grade 1 products are the most energy-saving, and level 5 is the most energy-consuming. It should also be reminded that only the label is considered energy-saving air conditioning.

CO is carbon monoxide.

Carbon monoxide, a carbon oxide, has the chemical formula CO and molecular weight, and is usually a colorless, odorless, and tasteless gas. In terms of physical properties, the melting point of carbon oxide is -205, the boiling point is, and the solubility in water is insoluble in water (20, which is not easy to liquefy and solidify.

In terms of chemical properties, carbon monoxide is both reducing and oxidizing, and can undergo oxidation reactions (combustion reactions) and disproportionation reactions. Industrially, carbon monoxide is the basis of one-carbon chemistry, which can be prepared by methods such as coke oxygen method, and is mainly used for the production of methanol and phosgene and organic synthesis.

Areas of application of CO

1. Chemical industry.

In the chemical industry, carbon monoxide is the basis of one-carbon chemistry. As the main component of syngas and various types of coal gas, carbon monoxide is an important raw material for the synthesis of a series of basic organic chemical products and intermediates, starting from carbon monoxide, it can produce almost all basic chemicals, such as ammonia, phosgene, alcohols, acids, anhydrides, esters, aldehydes, ethers, amines, alkanes and olefins.

2. Metallurgical industry.

In the metallurgical industry, carbon monoxide can be used to extract high-purity nickel from raw ore by using the thermal decomposition reaction of carbonyl metals, and can also be used to obtain high-purity powder metals (such as zinc white pigments) and produce certain high-purity metal films (such as tungsten film and molybdenum film). At the same time, carbon monoxide can be used as a reducing agent for refining metals, such as oxides used to reduce iron in orange steelmaking blast furnaces.
