Compressor type
Compressor wine cabinet is through the compressor for the main refrigeration system refrigeration electronic wine cabinet. The compressor electronic wine cabinet realizes refrigeration through its refrigeration system. The refrigeration system consists of 4 basic parts: compressor, condenser, throttling component and evaporator. The four pieces are connected in a certain order by the copper pipe to form a closed system, and the system is filled with a certain amount of refrigerant. The general refrigerant is Freon, R22 is usually used in the past, and some compressor Freon has been used R410A, R-404A, R407 and other new environmentally friendly refrigerants. Taking refrigeration as an example, the compressor sucks in low-temperature and low-pressure Freon gas from the evaporator, compresses it into high-temperature and high-pressure Freon gas, and then flows through the thermal expansion valve (capillary tube) to throttle into a low-temperature and low-pressure Freon vapor-liquid two-phase object. Then the low-temperature and low-pressure Freon liquid absorbs heat from the air in the space in the evaporator and becomes low-temperature and low-low-low-low-low-pressure Freon gas. After the indoor air passes through the evaporator, it releases heat and the air temperature drops. In this way, compression-condensation-throttling-evaporation cycles repeatedly, and the refrigerant continuously takes away the heat of the indoor air, thereby reducing the temperature in the space. During heating, the flow direction of the refrigerant is changed by switching the four-way valve, so that the outdoor heat exchanger becomes an evaporator, which absorbs the heat of the outdoor air, while the indoor evaporation becomes a condenser, which dissipates the heat indoors. To achieve the purpose of heating.
Semiconductor
Semiconductor wine cabinet is an electronic wine cabinet with semiconductor refrigeration chip electric refrigeration system. The electronic semiconductor wine cabinet is to connect direct current to the semiconductor refrigerator and absorb electric heat to cool it. A layer of frost can be formed in a small range in a few minutes. The working principle of semiconductor refrigeration device is based on Peltier principle. this 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, some other heat will be released at the joint besides joule heat, while the other joint absorbs heat, and this phenomenon caused by Peltier effect is reversible, when the current direction is changed, the joint that releases heat and absorbs heat will 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, I .e. Qab = I πab πab is called the relative Peltier coefficient between conductors A and B, and the unit is [V]. When πab is positive, it means heat absorption, on the contrary, it is heat release. Since heat absorption and heat release are reversible, the magnitude of πab =-πab Peltier coefficient depends on the properties of the materials forming the closed loop and the junction temperature. Its value can be obtained from the Seebeck coefficient αab[V.K-1] and the absolute temperature T[K] at the junction. πab = αabT is in phase with the Seebeck effect. The Peltier system also has additive properties, I .e: qac = Qab Qbc =(π AB π bc)I so the absolute Peltier coefficient has π AB = π a- π B
