Replace Commercial Refrigeration Thermostats Yourself .

It senses the temperature of the evaporator coil rather than air temperature. These two controls are not interchangeable. If you put an air sensing control in place of an evaporative sensing control, the evaporator unit will shut off permanently, causing the temperature to rise.


The APR Control externally unloads the compressor, keeping the evaporator coil at a constant temperature below dew point, thereby dehumidifying during the extended run time achieved. Extended run time is achieved by keeping the thermostat from being satisfied too

Refrigeration Basics - Controls

The sensing bulb of the control should be mounted so that it senses the evaporator inlet air. During the off cycle the constant fan recirculates the air in the box. The temperature of the air becomes an average of the product temperature, the wall temperature, any infiltrated air and any other loads such as caused by a person entering the box.

Installation and Table of Contents Operation Manual

and provide input to the controller from the following: defrost temperature, suction temperature, room temperature Each evaporator unit must be installed using proper refrigeration practices and codes. Make sure the piping is correctly sized and properly routed. It is highly recommended that the liquid and suction lines be insulated.

Air Conditioning - Thermostat

In all thermostats, the spring tension and point spacing may be varied by the operator to regulate evaporator cooling for comfort. Temperature is controlled by rotating a cam (via a knob control) which increases or decreases spring tension of a pivoting point. Part Identification - Thermostat . Relative Note This always appears relative to its .

REFRIGERATION BASICS: Optimizing System Performance Using .

Attempts to use the TXV to control any of these system variables will lead to poor system performance and possible compressor failure. The TXV responds to the temperature of refrigerant gas as it leaves the evaporator. This temperature is detected by the sensing bulb, which is located near the evaporator .

Don't Confuse a Frosted Evaporator Coil With Refrigerant .

Apr 08, 2020 · Severe cases of evaporator frosting can cause liquid refrigerant to return to the compressor. As mentioned above, a result of this insulating effect is a lower evaporator pressure, causing the temperature of the evaporator coil to be reduced to maintain the same desired refrigerated space temperature.

Beacon II™ Refrigeration Systems - Imperial

control sensor. When used in a normal cold store, this sensor measures the room temperature. For this reason it is normally located in such a way that it records the tempe-rature of the return airflow to the evaporator. The Refrigeration Controller then dis-plays and processes the temperature as the actual room temperature.

Common refrigerator problems - freezer not cold enough .

The temperature control board controls the compressor and other major components in the refrigerator. You can test it using the diagnostic test procedures provided in the tech sheet for the refrigerator. Replace the temperature control board if it doesn't work .

Jul 02, 2018 · The 195°F discharge temperature is caused by the evaporator and compressor running high superheat along with high compression ratios. When undercharged, do not expect the TXV to control superheat. The TXV may be seeing a combination of vapor and liquid at its entrance, so the evaporator will be starved of refrigerant and running high superheat.
