Discussion on the "pie" of refrigeration and compression facilities

Wang Zhepi is, the horsepower is the power unit. People learn to say that horsepower is horsepower, horsepower and then the palace is a horse, the power unit horsepower is divided into metric horsepower German language, Liu Ying said abbreviations as 代 code or no surrogate mother and English horse twitching machine Written as a code name. They are related to the statutory plan, and the burial relationship of the unit tile is the horsepower in February. Horsepower is resting. Horsepower is often confused when applied. It may be because of horsepower, so people often put it, Ling said it. The power unit used at the beginning of the horsepower is now the power unit of the motor in watts and kilowatts. Horsepower and horsepower motors refer to horsepower and horsepower. The size of the power drawn out of the farm shows the size of the motor.

For the refrigeration compressor, the power of the current motor such as the horsepower is used to indicate the relationship between the specifications of the compressor and the air volume of the compressor. Japan Hitachi live-type press machine specifications Bu cylinder volume specification cylinder volume Electrolux to the female compressor from the horsepower unit of the compressor specifications and its gas [volume correspondence between the compressor size indicates compression The size of the machine is the same as the size of the compressor. I searched for the specifications of the gas-anal volume agricultural compressor. For example, and their gas and anal volume are respectively resistant.

The stepless big compressor should be the pumping power of the motor of the big motor sister. There is no definite correlation between the pump's pumping work and its pumping power, the compressor's specifications, and its pumping power. The amount of power input depends on the turn of the motor in the coarse compressor, the torque and its own efficiency, as well as the efficiency of the compressor. Therefore, the motors of the same power have different pumping powers when they are driven by different types of compressors or compressors of different manufacturers. Even with the same motor D compressor, its work is not the same under different working conditions. Therefore, it is wrong to describe the specification of the compressor as its pumping power. The relationship between the gas volume of the compressor and its refrigeration depends on the volumetric efficiency of the compressor. Compressor manufacturers' design level and product quality, the different volumetric efficiency of compressors produced by different conditions are also different. Even with the same compressor, its volumetric efficiency changes with changes in its operating conditions. Therefore, there is no definite correlation between the specifications of the compressor related to the size of the air anus and its refrigeration.

Generally speaking, the technology, the quality, the phase is not much, or the compressors produced by the same manufacturer have larger specifications, and the larger and higher-efficiency compressors are excluded. The national unit and the unit system office listed the horsepower as the “common meter, unit to be excluded”. Undoubtedly we are counting, we should not use horsepower as a power unit, especially in legal documents. The application of statutory calculations, the unit "watts and kilowatts. And as a specification of the compressor, the actual use of the horsepower unit is not taken. For this reason, the pressure unit "Ba" mentioned here is also included in the "common meter that should be abolished," Unit', which is used to indicate the use of Yanqi pressure, Bayu, Kilograms, and Square meters. Especially in the exquisite pressure gauges in scientific trials, both at home and abroad are in units of Pakistan. Some people say that using horsepower as a power unit is not accurate. Imagine that the power of the same type of motor is less than a few watts between individuals, and more than a few tens of watts plus large horses, etc., can be said to be fine enough. Therefore, in the reality of the prevailing import and export of compressors, whether domestic, foreign, manufacturers, or Shangdong, consumers can understand the more, communicate with each other, horsepower still has its nominal or practical interest, in fact, horsepower They also have a certain correlation with the "statutory plan, unit", which is equivalent to indirect use of the law, the unit.

In winter, many homes began to let the air conditioner "rest". There are also many misoes that the air conditioner can be picked up without using air conditioners in winter. Yue's waiting for the next year to operate well. However, half of the repairs that the air-conditioner manufacturer found in the east are Because the air conditioner "rested a winter and the workers". In winter, it is very important to maintain the air conditioner. It cannot be ignored. In the winter, the air conditioner is usually used to prevent the air, rain and dust from being eroded. Air conditioners are divided into two types: internal and outdoor. Under normal circumstances, the consumer only chooses the room eve and regularly cleans the indoor unit. Before using the air conditioner, the air conditioner should be selected to cool the cold water in the air conditioner for half a day. In order to avoid leaving the cold water in the machine for a long time.
