To your heatcraft refrigeration products sales representative.
Refrigeration solenoid wiring diagram. Assortment of kenmore refrigerator wiring diagram. It reveals the parts of the circuit as streamlined forms and the power as well as signal links between the devices. Definitions solenoid valves are found in many applications and are commonly used in refrigeration and air conditioning systems. 1 a solenoid is a simple form of an electromagnet consisting of a coil of insulated copper wire.
Wiring at the unit cooler s will be as follows see wiring diagrams. A solenoid valveis an electromechanical valve frequently used to control the flow of liquid or gas. From this point forward ladder dia. 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.
This type of wiring diagram has branch runs all shown as parallel circuits going from the left line l1 to the neutral line n. A wiring diagram is a streamlined standard pictorial representation of an electrical circuit. The application of a liquid line solenoid valve depends mainly on the method of wiring the valve with the compressor control circuit. 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.
The components of a pump down system are a lpc a t stat and a solenoid valve which is installed in the liquid line. The transmission shift solenoids egr solenoid a c or hvac solenoids emission solenoids well most of your vehicle systems employ some form of. On multiple systems a solenoid valve may be used in each liquid line leading to the individual evaporators. 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. Variety of 12 volt solenoid wiring diagram. High voltage there may be high voltage on the defrost heater relay and the fan relay. The compressor will continue to pump refrigerant into the condenser and or receiver drawing it from the low side of the system.
When installed in that location it is called llsv for liquid line solenoid valve. Warranty consult the wiring diagram in the unit cooler and in the condensing unit for. 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. It also eliminates the possibility of refrigerant migrating to the compressor sump during the off cycle and washing out the oil at start up.
A wiring diagram is a simplified conventional photographic representation of an electrical circuit.
