Mid-temperature refrigerators use a “clop-loop” thermostat to defrost, sometimes requiring a timer to extend the “closed-loop” time. Below is a general diagram of a walk-in refrigerator © 2005 Refrigeration Training Services – Relay E3 # 2 , Refrigerator Controls and Timers v1.0

Defrost thermostat off-cycle is satisfied TS L 120V Solenoid opening N Solenoid closing BOX This is the base line of the refrigerant in the engine that uses the thermostat and drain solution. When the temperature is satisfied, the solenoid circuit is broken, closing the solenoid and stopping the flow of water to the expansion valve. The compressor operates until the suction pressure drops to the cut-off point of the low pressure control. The fan is a continuous line to keep air in the box when the compressor is off. Because the upper box is frozen, it will cause the coil to melt. A solenoid should be used whenever you have a remote control unit for at least 2 reasons. First, when the solution is cut off, it will remove all the refrigerant from the bottom of the system and store it in the receiver before the compressor shuts off. This prevents the refrigerant from moving and causing flooding. Second, the compressor has an easy starting time under no-load conditions.

The timer in the example consists of a series of normally closed (NC) contacts that cycle the refrigerant capacitor in continuous on and off cycles.

In this picture, when blackout is reached at 2:00 am, a series of wires turn the air on and off. Cash registers will be closed and refrigerators will be reopened at 4:00 p.m. L1 N Load © 2005 Refrigeration Training Service – Relay E3 # 2, Refrigeration Controllers and Timers v1.0

“Scheduled” This off-cycle purge gives the evaporator extra time to purge the air on the clock, turning off the character while the evaporator fan continues to operate.

These factors will make the system last longer without eliminating the normal “off-cycle” from the thermostat. Continuous steam causes frostbite, which must be removed at least once a day. The “B” or blue wire is the common wire. The 1-2 switch connection controls nothing in this example. It happens to be on a Paragon clock that uses a 230 volt circuit. If it is a 115 volt fan, a Paragon clock can be used. Wire “A” or red wire is disconnected from connection 3-4 which controls the bottom side of the pump solution valve. Note The fan must be running continuously when the compressor is off to remove cold air from the top of the refrigerator. Peak ice time in these groups is around 2am for an hour or two. This usually has enough time to remove the accumulation during the day and is done without anyone opening the door which could cause the box to overheat.

The water cooler needs heat to help reduce the vapor of the evaporator, stop the cooling and delay the fan, the control is needed to turn the system to lower the safety temperature, to prevent overheating of the refrigerator clock is necessary. All low temperature evaporators operate in the cold and must be removed. Since the air in the refrigerator below is cold, heat must be added to the evaporator to freeze it. This damage is usually achieved by external heating or internal heating. © 2005 Refrigeration Training Service – Relay E3 #2, Refrigeration Control and Timer v1.0

Safety Heater DTFD (Frost Stop / Delay) Electric defrost heater The steam end of this refrigerator features: A defrost dryer. Terminal pads for defrost wiring. The wire from the clock is connected to this point, a 3-wire extension delay extension. It stops freezing and resets the cooling system, delaying the expansion of the water heater until the temperature reaches 25 ° A. The large 2-wire control opens the circuit to the heater if it is too high. Designed for cold filling.

The following clock is scheduled to defrost 4 times in 24 hours. The “failsafe” setting is a backup to stop the defrost if the defrost takes too long (about 45 minutes on a standard clock). – E3 # 2 Refrigerator Management with Timer v1.0
