Is the temperature of the gas lines in an ice maker lower than that of the liquid lines?
Thread Content
Why is the gas pipeline of an ice maker colder than the liquid pipeline? The flow path of the refrigerant R22 is as follows: screw compressor – oil separator – condenser – liquid receiver – gas-liquid separator – dry evaporator – gas-liquid separator – screw compressor. The reason why the gaseous R22 coming out of the evaporator has a very low temperature and causes ice to form on the pipe surfaces is that the pipes need to be insulated ； The temperature of the liquid R22 entering the evaporator is relatively high; the outer surface of the pipes feels very hot (probably around 50°C), and the temperature of the liquid storage tank is likely around 60°C as well

This is a natural phenomenon) – oil separator – condenser (the external medium is used for cooling, with the aim of reducing the temperature of the gas and removing the heat from within it. But since it is air-cooled, the temperature after cooling depends on the ambient temperature) – liquid reservoir – gas-liquid separator – dry evaporator (vaporization occurs, and the temperature drops). This is a natural phenomenon) – gas-liquid separator – screw compressor. Compression turns it into a liquid; the temperature of the medium rises ； Then it is cooled using outdoor media (air conditioning uses outdoor air for cooling, with fans to facilitate the flow of outdoor air). Water cooling is also used in industry.) ； The pressure is reduced, causing the gas to vaporize; as a result, the temperature of the medium drops, and it absorbs the heat from the room.
The pressure is different; it’s only the temperature that matters, not the pressure. That’s just being unfair
