In order to alleviate climate warming, students should save energy. How many degrees should the air conditioning temperature be controlled in summer?
As follows:
Air conditioner, namely air conditioner, refers to the equipment that manually adjusts and controls the temperature, humidity, flow rate and other parameters of ambient air in buildings or structures. Air conditioning generally includes cold source/heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. Mainly includes: refrigeration host, water pump, fan and pipeline system.
The terminal equipment is responsible for carefully handling the air state by using the cold heat from transmission and distribution, so that the air parameters of the target environment can meet certain requirements. Air conditioning is an indispensable part of modern life. While providing people with coolness and warmth, air conditioning is also prone to diseases, such as "air conditioning disease", which needs to be used with caution.
The main forms of air conditioning are: cabinet air conditioning, on-hook air conditioning, water air conditioning, window air conditioning (semi-indoor and semi-outdoor), central air conditioning, one-on-two air conditioning (one outdoor unit controls two indoor units at the same time) and so on. Working process of specific volume pair between teeth in air-conditioning compressor. The gas turned to the side where the internal thread and the external thread meet each other is compressed.
This side is called the high pressure area; On the contrary, when the screw turns to the opposite side, the volume between teeth expands and it is in the suction stage, which is called low pressure area. These two areas are separated by the contact line between the tooth surfaces of the internal thread and the external thread. It can be approximately considered that the planes where the axes of the two screws are located are the planes of the high pressure region and the low pressure region.
A compressed refrigerant (such as freon) becomes a liquid. Then refrigeration is carried out by using the endothermic phenomenon when the liquid becomes gaseous under normal pressure. The air density is very small. You have an injection. Fill the needle tube with air, block the air outlet by hand and push the needle tube to compress the air. Gas can be compressed by one-third of the volume with a needle tube.
The compressor sucks the working medium vapor with lower pressure from the evaporator, sends it to the condenser after the pressure rises, condenses it into liquid with higher pressure in the condenser, becomes liquid with lower pressure after throttling by the throttle valve, and then sends it to the evaporator to absorb heat and evaporate it into vapor with lower pressure, thus completing the refrigeration cycle.
For some applications, gas must pass through a long tube (usually coiled into a solenoid) to dissipate heat into the surrounding air. Heat conducting metals, such as copper, are often used to transport steam. In order to improve the efficiency of condenser, fins are usually attached to the pipeline to accelerate heat dissipation. The radiator is a flat plate made of metal with good thermal conductivity.
