What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
What happens to the heat in a system and in the surroundings in an exothermic reaction?
the system releases heat,meaning that energy is generatered.
What is latent capacity?
the heat released or absorbed by a body or a thermodynamic system during a process that occurs without a change in temperature.
What is absorbed by the earth changing the rays to heat?
ultraviolet rays are absorbed by the earth changing the rays to heat
What is the purpose of an evaporator?
An evaporator in a refrigeration system works by passing warm air over it's coils. The warmth of the air heats the liquid refrigerant inside, causing it to boil into gas. At the same time, the air looses it's heat and turns cold. It is heated by the surrounding and is passed through again and again until the surrounding is the same temperature as the liquid refrigerant. Then, the system shuts off, or cycles back, depending on the metering device.
What are the function of the refrigerant in the refrigeration system?
The refrigerant in the refrigrration system absorbs large quantities of heat and releases it to the atmosphere
Evaporator in a refrigeration sistem?
The Evaporator is the part of a refrigeration system that absorbs heat. Its counterpart is the condenser which is used to remove heat that was absorbed in the evaporator.
Principles of operation of vapour compression refrigeration system?
The principle of refrigeration is to remove heat from one area (i.e inside your fridge) and locate it to another area (i.e outside of your fridge). Air is not brought in from the outside of the fridge the heat is absorbed by the evaporator inside the fridge which has refrigerant inside it, this refrigerant at low pressure is at low temperature inside the evaporator so the heat from the product inside the fridge is absorbed by the evaporator (as heat always transfers from the hotter object to the colder object) which has a fan to circulate the air around the fridge. Then the refrigerant is pushed around the pipework by the compressor to the condenser where the refrigerant is hot from the heat out of the fridge, because the outside air will be lower than that of the pressurized refrigerant the heat is absorbed by the ambient air which leaves the refrigerant cooler and lower pressure so when its back into the evaporator it can absorb more heat and expel it into the ambient air. There are 5 main components in a normal refrigeration system like on your fridge:- Compressor Condenser Expansion Device or Capillary tube Evaporator Thermostat The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization. As it cools, the refrigerant condenses into liquid form and flows through the expansion valve. When it flows through the expansion valve, the liquid refrigerant is allowed to move from a high-pressure zone to a low-pressure zone, so it expands and evaporates. In evaporating, it absorbs heat, making it cold. The coils inside the refrigerator allow the refrigerant to absorb heat, making the inside of the refrigerator cold. The cycle then repeats.
The function of the condenser is too increase refrigeration pressure lose the heat from the refrigerant add heat to the refrigerant reduce the fridge aration pressure?
lose the heat from the refrigerant
When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?
Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant
What is the function of the evaporator in a refrigeration or air- conditioning system?
The three main functions of the evaporator are to:a. absorb heat from the medium being cooled.b. allow the heat to boil off the liquid refrigerant to a vaporc. allow the heat to superheat the refrigerant vapor

What is net refrigeration?
The net refrigeration effect is the amount of heat each pound of refrigerant absorbs from the refrigerated space. This heat produces useful cooling.
Why freon gas compressed in compressor in ac?
Air conditioning works by having the refrigerant undergo changes of state of the refrigerant between a liquid and a vapor, and also through heat exchanges, where heat is absorbed by the refrigerant, and is then exchanged to the ambient air both in the condenser and evaporator. In order for the heat absorbed by the refrigerant to be able to be exchanged to the ambient air, the temperature of the refrigerant must be significantly higher than that of the ambient air. Compressing the refrigerant into a high pressure vapor (which the compressor does) increases the heat of the refrigerant, as, when under high pressure, the molecules rub together more frequently, thus generating additional heat to the heat already absorbed by the refrigerant. This facilitates the heat transfer necessary for the proper performance of an air conditioning system.
