The Difference Between Cabinet Air Conditioner And Peltier Air Conditioner

1. Different working principles

Refrigeration principle of cabinet air conditioner: the vapor compression refrigeration system is composed of compressor, condenser, throttling device, evaporator and other four main parts. The working medium circulation, in which the pipes are connected at one time to form a completely closed system. The refrigerant circulates in the closed refrigeration system in the state of fluid, and continuously absorbs heat from the evaporator through phase change, And in the condenser to release heat, so as to achieve the purpose of refrigeration.

The working principle of semiconductor air conditioner is based on the Peltier principle. The effect was first discovered by j.a.c. Peltier in 1834, that is, when the circuit composed of two different conductors A and B is connected with direct current, in addition to Joule heat, some other heat is released at the joint, while the other joint absorbs heat, When the current direction is changed, the exothermic and endothermic joints also change. The heat absorbed and released is proportional to the current intensity I [a], and is related to the properties of the two conductors and the temperature of the hot end

2. Environmental protection

Semiconductor air conditioning does not use freon and other refrigerants, which has no adverse impact on the environment. The cabinet air conditioning will cause damage to the environment

3. Power

The energy conversion rate of semiconductor air conditioner is low, and the power required for the same cooling capacity is much more than that of cabinet air conditioner
