What are the influencing factors of the cooling speed of the cold storage system

1. The cold storage has a large loss of cold due to poor heat insulation or sealing performance 　　 Poor thermal insulation performance is due to insufficient insulation thickness of pipes, warehouse insulation walls, etc., and poor thermal insulation and thermal insulation effects.

The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.

What is the difference between heating 24 ℃ and cooling 24 ℃

Regardless of the room temperature, as long as the air conditioner is in the cooling mode and is in a working state, the wind blown out is cold wind. To put it bluntly, the temperature of the blown air is determined by the operation mode of the air condit器2䀀

Noise Control of Ash Removal Air Compressor Room in Thermal Power Plant

The 240 mm clay bricks are closed to eliminate the influence of direct sound on the outside world. The steel window on the other side of the workshop is fixed (not open), and a layer of airtight and fixed sound insulation windows is added on the outside. The distance between the two windows is 100 mm, the sound insulation window uses 8 mm thick glass.
