Solenoid Valves for Refrigeration, Air Conditioning, and Heat Pump Systems

Form #: 620-101
This chapter covers the function of solenoid valves as used in refrigeration, air conditioning and heat pump systems.

Electric Valves for Refrigerant Control

Form #: 620-118
This chapter covers the four basic types of electric valves (solenoid, analog, heat motor, step motor), digital linear actuators/resolution, actual control hardware (PID control and algorithms, integral control, proportional control), pressure temperature tables and troubleshooting & failure modes among other topics of interest.

Thermostatic Expansion Valves - Part 1

Form #: 620-40A
This chapter covers the theory of operation, proper selection, and application of thermostatic expansion valves (TEVs).

Automatic System Capacity Controls

Form #: 620-41
The purpose of this chapter is to review the fundamentals of Automatic System Capacity control methods, based on new developments and experience in the refrigeration and air conditioning industry.

The Capillary Tube and Its Application to Small Refrigerating Systems

Form #: 620-42
It is the purpose of this chapter to present a simplified explanation of the capillary tube and to describe simply and in a straightforward fashion the steps to be taken in making a conversion.

Servicing Cap Tube Systems

Form #: 620-43
This chapter provides important service information on the cap-tube’s function, advantages and disadvantages, problems and corrective measures.

Thermostatic Expansion Valves - Part 2

Form #: 620-74A
This chapter covers knowing how to apply, install and service the thermostatic expansion valves (TEVs).

Pressure Regulators for Refrigeration, Air Conditioning, and Heat Pump Systems

Form #: 620-97
Two basic types of pressure regulators are covered in this chapter: (1) Upstream pressure regulators, or those which control from an inlet pressure signal. (2) Downstream pressure regulators, which control from an outlet pressure signal. It is necessary to know what the intended use of the regulator will be before the tonnage, refrigerant, temperature range, connections, and pressure range conditions are selected All piping diagrams contained in this chapter are schematics for illustration purposes only.

Capillary Tubes: Theory and Practice

Form #: 620-98
This chapter covers the importance of the cap tube as a refrigerant control vs. what you only may see as a slender copper tube with a small inside diameter.
