Best Answer

Starting with liquid refrigerant:

  1. The pump pushes the refrigerant, under pressure, through an orifice
  2. The refrigerant sprays through the orifice into the low pressure side of the system
  3. The refrigerant flashes to vapor and absorbs heat from the coils of the evaporator
  4. The heat-laden refrigerant vapor moves into the condenser where the heat is dumped to the atmosphere and the refrigerant condenses to a liquid
  5. The liquid enters the pump and begins the cycle again.

A refrigerator works using a thermostat. It automatically switches itself on when needed and off when not needed. A thermostat works (putting it on) by using two strips of different metals which have a charge which is positive in them, usually Copper(Cu) and Aluminium (Al) or Copper (Cu) and Iron (Fe). One metal expands well and one doesn't. Thus the one that doesn't is pushed by the one that does (when under heat), and they both touch a metal that has a negative charge in it, thus completing the circuit and keeping the fridge on. (putting it off) When the metal cools down, it goes back to it's normal position and thus breaks the circuit ,keeping the fridge off.

it has an evaporator in the fridge and it cools down the gasses and turns them into a liquid which is subzero and the the liquids cool down your food.

The refrigerator keeps the food you store it cold. It saves the food so it doesn't go to waste.

Refrigeration is a process in which work is done to move heat. It was a closed-cycle that could operate continuously, as he described in his patent.

Why refrigeration cycle is called reverse carnot cycle?

The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.

Explain the reverse carnot cycle and from them go to ac?

Carnot Cycle is an ideal thermodynamic cycle that describes the functioning of a perfect heat engine. In the refrigeration system we need a cooling effect. So, in effect, refrigeration cycle is reverse in process than that of a carnot cycle, and ofcourse not ideal. Air-conditioners also run on the similar cycle as refrigerators.


What is the net refrigeration effect in the refrigeration cycle?

The quantity of heat that each pound of refrigerant absorbs from the refrigerated space to produce useful cooling.


How do you improve the performance of vapor compressor refrigeration cycle?

In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows: • evaporation, • compression, • condensation, and • expansion.

What are the four basic components in the vapor compression refrigeration cycle?

Vapor compression in the refrigeration cycle is the process which turns heated vapor into a cold liquid. This allows the coolant to flow through the condenser and cool the air.
