What are the different types of cooling parts?
refrigerators have taken a bumpy journey over the past 262 years. William Cullen created the first refrigerator, although it was not suitable for any use daily. Only in 1834 was the practical refrigerator invented by Jacob Perkins. Since the 1930s, the refrigerators made a huge step forward. The cooling units have changed drastically over the past 200 years. The cold parts are basically divided into four main places with one area used twice. One of the most important cooling parts is the compressor. The compressor begins and ends the whole cooling process. If it drops, the whole system fails. The main key is the cooling gas regarding the compressor. The refrigerant is a liquid inside the refrigerator used to cool to a low temperature, creating colder temperatures inside. In today's main industrial installations, companies are starting to use ammonia instead of refrigerant. Ammonia cools at 27 degrees under zero fahrenheite, ie 32 degrees below zero Celsius. The compressor begins to squeezeGas gas and creates higher pressure and refrigerant temperature.
From the compressor to the heat exchange coils on the outside of the refrigerator, the coils help to keep the refrigerant pressure down through the heat scattering. This process is performed through pressure. When cooling, the refrigerant begins to condense back into the liquid when it flows through the expansion valve. The extending valve is the last item of the cooling part on the outside of the refrigerator. When traveling via the expansion valve, the refrigerant goes from high pressure to low pressure.
When the expansion valve flows through the expansion valve, the refrigerant quickly moves from a httles with warmer temperatures to a lower pressure situation with colder temperatures. The refrigerant passes through another set of coils for heat exchange. These heat exchange coils remain on the inside of the refrigerator. When the expansion valve passes through the expansion valve, the refrigerant expands and evaporates. The evaporation process is absorbed and the temperatures drop.In temperatures that drop in the coils for heat exchange inside the refrigerator, temperatures in the refrigerator also decrease. The coils for heat exchange will lead back to the compressor, which is on the outside of the refrigerator and the cooling part will start the cycle again.
