Description

Air conditioner for subway station

Technical Field

The invention relates to the technical field of air conditioning equipment, in particular to an air conditioner for a subway station.

Background

Currently, air conditioners are widely used in subway stations.

The peltier effect means that when a current passes through a loop formed by different conductors, in addition to irreversible joule heat generation, heat absorption and heat release phenomena occur at joints of the different conductors respectively along with the difference of current directions. This was discovered by j.c.a. peltier in 1834. If current flows from conductor 1 to conductor 2 through the wire, the amount of heat absorbed per unit area at conductor 1 per unit time is proportional to the current density through conductor 1.

The simple can be understood as follows: under the action of an external electric field, electrons generate directional motion, and a part of internal energy is brought to the other end of the electric field.

When current passes through a loop formed by different conductors, in addition to generating irreversible joule heat, heat absorption and heat release phenomena respectively occur at joints of different conductors along with different current directions. This was discovered by j.c.a. peltier in 1834. The movement of charge carriers in the conductor creates a current. Since charge carriers are at different energy levels in different materials, excess energy is released as it moves from high to low energy levels; conversely, when moving from a low level to a high level, energy is absorbed from the outside. Energy is absorbed or released as heat at the interface of the two materials. This effect is reversible, with the inversion of the current direction, converting endothermic to exothermic.

The french scientist peltier discovered thermoelectric cooling and heating phenomena-i.e. thermoelectric effect-in 1834. A pair of thermocouples is formed by N, P type materials, when direct current is introduced into the thermocouples, heat absorption and heat release phenomena are generated at the junctions of the thermocouples due to different introduction directions of the direct current, and the phenomena are called Peltier effect.

Semiconductor refrigerators, also called thermoelectric refrigerators or thermoelectric refrigerators, use the peltier effect.
