Refrigeration Solenoid Wiring Diagram
High voltage there may be high voltage on the defrost heater relay and the fan relay.
Refrigeration solenoid wiring diagram. It also eliminates the possibility of refrigerant migrating to the compressor sump during the off cycle and washing out the oil at start up. Definitions solenoid valves are found in many applications and are commonly used in refrigeration and air conditioning systems. From this point forward ladder dia. The components of a pump down system are a lpc a t stat and a solenoid valve which is installed in the liquid line.
Types of wiring diagrams there are three basic types of wiring diagrams used in the hvac r industrytoday. It may be wired so the valve is energized only when the compressor is running. The transmission shift solenoids egr solenoid a c or hvac solenoids emission solenoids well most of your vehicle systems employ some form of. A wiring diagram is a simplified conventional photographic representation of an electrical circuit.
To your heatcraft refrigeration products sales representative. Warranty consult the wiring diagram in the unit cooler and in the condensing unit for. Wiring at the unit cooler s will be as follows see wiring diagrams. They look like the rungs in a ladder hence the name ladder schematic.
This type of wiring diagram has branch runs all shown as parallel circuits going from the left line l1 to the neutral line n. Variety of 12 volt solenoid wiring diagram. When installed in that location it is called llsv for liquid line solenoid valve. On multiple systems a solenoid valve may be used in each liquid line leading to the individual evaporators.
The application of a liquid line solenoid valve depends mainly on the method of wiring the valve with the compressor control circuit. The first and most common is the ladder diagram so called because it looks like the symbols that are used to represent the components in the system have been placed on the rungs of a ladder. Assortment of kenmore refrigerator wiring diagram. A system pump down utilizes a solenoid valve in the liquid line when the system set point temperature has been satisfied the solenoid valve will close.
The fuel injector itself is a type of solenoid. A wiring diagram is a streamlined standard pictorial representation of an electrical circuit. A solenoid valveis an electromechanical valve frequently used to control the flow of liquid or gas. It reveals the parts of the circuit as streamlined forms and the power as well as signal links between the devices.
The efm evaporator fan motor must run all the time so that the box temperature stays uniform and the thermostat senses the average box temperature not some pocket of stratified air.
