\n<\/a><\/p>\n

Purpose<\/p>\n

\u2022 The expansion valve atomizes liquid refrigerant to facilitate cooling of the evaporator.<\/div>\n



\n<\/a><\/p>\n

Function<\/p>\n

\u2022 The expansion valve reduces the pressure of liquid refrigerant rapidly to facilitate vaporization of the atomized refrigerant at the evaporator, and adjusts the refrigerant amount sent into the evaporator.<\/div>\n



\n<\/a><\/p>\n

Structure\/Construction<\/p>\n

\u2022 The expansion valve consists of the following parts:<\/div>\n
\n
\n
\u2015 Diaphragm<\/div>\n
\u2015 Temperature sensor<\/div>\n
\u2015 Shaft<\/div>\n
\u2015 Expansion valve body<\/div>\n
\u2015 Ball valve<\/div>\n
\u2015 Spring<\/div>\n<\/dd>\n<\/dl>\n\n\n\n

\n<\/a><\/p>\n

Operation<\/p>\n

\u2022 Adjustment of the refrigerant amount supplied to the evaporator is performed by the ball valve opening angle in the expansion valve.<\/div>\n
\u2022 The opening angle adjustment is performed according to the balance of the following forces:<\/p>\n\n\n\n

\u2015 Refrigerant pressure (Pd) in diaphragm<\/div>\n
\u2015 Refrigerant gas pressure (PI) of evaporator under diaphragm<\/div>\n
\u2015 Spring force (Fs) pushing up ball valve<\/div>\n<\/dd>\n<\/dl>\n
\u2022 If the refrigerant gas temperature from the evaporator increases, the expansion valve increases the amount of refrigerant according to the following operations:<\/p>\n\n\n\n
<\/td>\n\n\n\n\n
<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\n
\n
1. The temperature of the temperature sensor tightly sealed against the diaphragm increases.<\/div>\n
2. The refrigerant in the diaphragm warms and the Pd increases.<\/div>\n
3. If this Pd increases more than PI + Fs, the diaphragm is pressed down.<\/div>\n
4. The shaft installed to the temperature sensor end presses down the ball valve.<\/div>\n
5. The amount of refrigerant is increased.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 If the refrigerant gas temperature from the evaporator decreases, the expansion valve decreases the amount of refrigerant flow according to the following operation:<\/p>\n\n\n\n

\n
\n
1. The temperature of the temperature sensor tightly sealed against the diaphragm decreases.<\/div>\n
2. The refrigerant temperature in the diaphragm decreases and the Pd decreases.<\/div>\n
3. The Pd decreases less than PI + Fs.<\/div>\n
4. The ball valve installed to the temperature sensor end is pressed up.<\/div>\n
5. The amount of refrigerant is decreased.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
