Refrigeration and Air Conditioning Expect more from us T-TE 2 Product Presentation , JBM page 6 T/TE 2 Thermostatic Expansion Valve The T/TE 2 will control and maintain the amount of refrigerant to be injected into the Evaporator. It does this by keeping the Superheat Constant where the sensor is mounted on the suction line (In a constant load scenario)

Refrigeration and Air Conditioning Expect more from us T-TE 2 Product Presentation , JBM page 13 Function of the T/TE 2 The TEV will try to keep a constant superheat at a constant load situation If there is a change in load the TEV will open more at increasing load and open less at decreasing load, and again try to keep a constant superheat The opening degree is decided by a balance between the opening force and the closing forces Pressure in the Power element is the opening force (Sensor temperature) Pressure from the refrigerant is a closing force Pressure from the spring is the other closing force

Refrigeration and Air Conditioning Expect more from us T-TE 2 Product Presentation , JBM page 26 WHY ? To be able to accurately inject the amount of refrigerant required into the evaporator.

Refrigeration and Air Conditioning Expect more from us T-TE 2 Product Presentation , JBM page 27 WHEN ? Every time there is a refrigeration system there should be one TEV for each evaporator (If not another means of throttle device is used)

Refrigeration and Air Conditioning Expect more from us T-TE 2 Product Presentation , JBM page 28 HOW ? By mounting the TEV in the refrigeration circuit with any necessary adjustment

Refrigeration and Air Conditioning Expect more from us T-TE 2 Product Presentation , JBM page 29 Where ? Always at the inlet of the evaporator
