The Engineering Mindset - In this video we look at how a refrigeration cycle works and use colour coding to see how the temperature and pressure changes throughout a system. We include photographs of real items so you know what to look for in the real world.
Created by AC Service Tech LLC - In this HVAC Video, I Explain Superheat and Subcooling in the Refrigeration Cycle to Understand the Operation Easier! I go over how to understand the importance of both Superheat and Subcooling. I go over the refrigeration cycle, where superheat is found and what will happen if a Piston or capillary tube system is overcharged in terms of compressor life. I go over what it means to have a low charge when you have a txv in reference to heat absorption in the evaporator coil as well as other tips!

Created by Refrigeration System and Cold Rooms - n This Video We Describe The Types Of All Condensers Working In Refrigeration System. There Are Three Types Of Condensers Working In Refrigeration System. 1.Air Cooled Condensers 2.Water Cooled Condensers 3.Evaporative Condensers
Created by Majesto Teaching - In this video, I am going to talk about WHAT IS EXPANSION VALVE? & DIFFERENT TYPES OF EXPANSION VALVES USED IN REFRIGERATION SYSTEM. WHAT IS EXPANSION VALVE? Expansion valves are devices which used in refrigeration system for control the flow amount of refrigerant in system and it also removes the pressure from the flowing refrigerant. There are two functions of Expansion Valve: 1. It control the flow amount of refrigerant which is be flow in the evaporator. 2. it maintain the difference between high pressure line & low pressure line. For know different types of expansion valve, first we should know what are expansion valves because it is very helpful to understanding WHAT IS EXPANSION VALVE? & DIFFERENT TYPES OF EXPANSION VALVES USED IN REFRIGERATION SYSTEM. DIFFERENT TYPES OF EXPANSION VALVES USED IN REFRIGERATION SYSTEM. 1. HAND OPERATED/ MANUAL EXPANSION VALVE. 2. AUTOMATIC EXPANSION VALVE. 3. THERMOSTATIC EXPANSION VALVE. 4. FLOAT VALVE- A. LOW SIDE FLOAT VALVE. B. HIGH SIDE FLOAT VALVE. 5. ELECTRONIC EXPANSION VALVE. 6. CAPILLARY TUBE.
Created by Freak Engineer - This video will talk about one of the important part of any air conditioning system, that is, Evaporators.. The three types are Shell & Tube used in Chillers, Fin (Cooling Coil) used in A/C units and Plate Surface used in Domestic Refrigeration.
Produced by Explain Like I'm Five - In this quick video, we will look at a brief history and evolution of refrigerators. Before the invention of the refrigerator, ice houses were used to provide cool storage for most of the year. Placed near freshwater lakes or packed with snow and ice during the winter, they were once very common. The Greek and Roman civilizations transported a large amount of snow and ice from the mountains, put it into storage pits and covered it with insulating material.
Created by RepairClinic.com - Refrigerator not cold enough or freezing food? This video provides information on how a refrigerator works and offers troubleshooting tips to assist you in diagnosing and repair. Here is a list of the most commonly replaced parts associated with each refrigerator symptom: Fridge not cold enough: evaporator or condenser fan motor, start relay, control thermostat Fridge not defrosting: defrost control board, timer, heater assembly, thermostat Fridge is too noisy: fan blade, evaporator or condenser fan motor, compressor Fridge is too warm but freezer is cold: evaporator fan motor, damper control, thermistor, control board Fridge leaking water: water tank assembly, water inlet valve Fridge freezing food: thermostat, thermistor, control board, damper control
Created by Engineering Mindset - In this video we will be learning the basic types of refrigerants, their history and future as well what impact they've had on our environment. Covering CFC, HCFC, HFC, HFO, Carbon dioxide, ammonia, CH, ozone layer depletion and greenhouse gases.
Created by Engineering Mindset - In this video we will be learning how refrigerants work in HVAC systems such as refrigerators, air and water cooled chillers as well as split a/c units. The refrigerant removes heat from the building and transfers it into the ambient outside air to produce air conditioning.
