What is flash chamber in refrigeration?
A flash chamber is a device which separates liquid from vapors. Only liquid is then passed to evaporator and the vapors will be passed to the compressor directly. This flash chamber between the condenser and evaporator is known as flash intercooling.
What does quality mean when referring to a refrigerant?
In thermodynamics, vapor quality is the mass fraction in a saturated mixture that is vapor; in other words, saturated vapor has a “quality” of 100%, and saturated liquid has a “quality” of 0%. By this definition, a saturated vapor has q = 0. A saturated liquid has q = 1.
What is the use of a flash chamber in VCR system?
What is the use of a flash chamber in VCR system? Explanation: Flash chamber is used to separate vapour and liquid refrigerant. It is an insulated container and separates both forms by using the centrifugal effect.
What are the main parts of a refrigerator?

What are the benefits of a refrigerator?
The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food.
What makes a smart fridge smart?
Smart refrigerators include internal cameras, more flexible user-controlled cooling options, and the ability for you to interact with its features using your smartphone or tablet when away from home.
What are the uses of fridge?
A refrigerator is a machine for keeping things cold. It is sometimes called a fridge or an icebox. It is normally maintained at 4-5 degree Celsius for household use. People put food and drinks in it, to keep those items cold or good (unspoiled) for a longer time.
Why is it called refrigerator?
The word refrigerator originates from the Latin verb refrigerare which was derived from the Latin adjective frigus, meaning cold.
What are the parts and functions of a refrigerator?
Internal Parts of a Refrigerator and its Functions
- Compressor. A compressor is the main part of a refrigerator.
- Refrigerant. Refrigerant is a cooling liquid that spreads inside the refrigerator and carries out the cooling part.
- Condenser.
- Evaporator.
- Thermostat.
- Defrost System.
- Diffuser.

What is the main function of compressor in refrigerator?
The compressor is the heart of the refrigeration system. The compressor acts as the pump that moves the refrigerant through the system. Temperature sensors start the compressor’s action. Refrigeration systems cool objects through repeated refrigeration cycles.
Is R134a an ideal gas?
3. As mentioned in the introduction, the working fluids are mainly treated as ideal gas previously. 4, R134a is used as a typical refrigerant, and the difference is really large when its property obeys the ideal gas law and real gas law.
Is R134a a CFC?
R-134A belongs to a group of chemicals called hydrofluorocarbons (HFCs) and is also known as HFC-134A. HFC-134A was developed to replace chlorofluorocarbon (CFC) refrigerants that contain chlorine, which damages the ozone layer.
Do you charge 407C as a liquid?
Charging: Due to the zeotropic nature of R-407C, it should be charged as a liquid to prevent fractionation (changes in refrigerant composition due to vapor charging.
