Do not understand ah, general repair air conditioning is to see that MPa ah, this temperature is what temperature ah? What's the saturation temperature? Oh, thank you
It is the temperature of the refrigerant in the corresponding pressure, that is to say that you read on the table that the refrigerant pressure (flow or static) temperature, such as your performance in the work under pressure, if the refrigerant R502 is 38 degrees, such as R12 is -28 degrees, such as working pressure in 4kg R502 is -5, R12 is 15 degrees, such as R22 is 0 degrees.See a circle of pressure are the same, but different units, you remember what units will see, for example, do you remember is MP or KG, see the corresponding circle, the temperature measuring equipment is to see you is what refrigerant.The saturation temperature is the boiling temperature of the refrigerant under this pressure.
In order to observe whether the air conditioner or refrigerator is running properly, the pressure of the refrigerant and the corresponding temperature is one of the parameters.
There are two main air conditioning test pressure, a condenser outlet pressure, a back pressure evaporator, the refrigerant from the condenser outlet state is liquid, so the pipe is fine, the refrigerant from the evaporator outlet state is gaseous, so thick pipe.Repair air-conditioning generally look at these temperatures:1. indoor air outlet temperature, used to determine whether the normal air conditioning.2., the condenser outlet temperature, used to determine whether the condensation is too cold, the greater the supercooling, the better.3., the evaporator outlet temperature, used to determine whether the gas back overheating, overheating is too large, small is not good.Notice that the outdoor unit is a condenser when it is cooled and the chamber is an evaporator.Saturation temperature is the temperature in which a liquid evaporates and a vapor condenses in a dynamic equilibrium state, i.e., a saturated state. Saturation temperature is related to pressure.
