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