3. Parts
3.1. Evaporator coils The main function of this is to turn the liquid refrigerant into it's gas form through evaporation. Hence, cooling it's surrounding (The inside of the fridge)
3.1.1. This is also typically made with copper, steel, or aluminum.
3.2. Compressor This is what pumps the vapor refrigerant through the whole fridge and it also allows it to increase both the temperature and pressure of the cooling agent.
3.2.1. It is typically made of copper, aluminum, and steel.
3.3. Expansion Valve This is usually a thin piece of tubing that is used to route liquid refrigerant into evaporators.
3.3.1. This mostly contains brass, stainless steel, and a liquid-filled bulb
3.4. Condenser coils This works hand in hand with Compressor, turning vapor refrigernant into it's liquid form. Allowing the compressor to increase pressure to fuel the condensation process.
3.4.1. This is mostly just made of copper and aluminum
3.5. Thermostat Control This allows the user to be able the control the temperature within the Fridge.
3.5.1. They made of two long, thin strips of metal, usually brass and steel
4. use phase
4.1. High energy consumption
4.1.1. energy-saving modes
4.1.1.1. Energy-efficient motors
4.1.2. Enviromental impacts
4.1.2.1. Use of low-Global Warming Potential refrigerators ( natural refrigerants like propane or CO2).
4.1.2.1.1. If Refrigerants aren't properly dispose of they are capable of causing major damage to the environment as it's a greenhouse gas which means it's capable of trapping heat. It's also very toxic to the environment to both human and wildlife, causing in humans if inhaled. Headaches, dizziness, unconsciousness, or even death.
