According to Alex Imholtz ( http://www.otal.umd.edu/~vg/amst205.F97/vj09/project5.html ) , gas refrigerators work this way :\n\nsection having a series of coils containing steam. The steam is created via a gas flame. Strong liquid (ammonia mixed with water) flows over the coils and the heat from the steam causes it to boil. As a result of the boiling, the strong liquid gives off ammonia vapor which exits the generator (2). This ammonia gas leaving the generator contains a small percentage of water and is somewhat warm. The gas enters the rectifier which is an amalgam of a heat exchanger and condenser created to purify the gas by taking away the heat and water. The heat from the gas is removed by liquid flowing though the rectifier. The cooling of the gas is what removes the water vapor. The water vapor condenses and drips back into the generator (3). The ammonia gas, however, proceeds to the condenser. It is here that the ammonia vapor is reduced to a denser form - liquid. The condenser consists of a ladder of tubes parallel to one another. Water flows downward over the outside of the tubes, taking heat from the warm gas flowing through them. The temperature decreases causing the ammonia gas to change phases. At the bottom of the condenser, liquid ammonia flows out (4). This anhydrous ammonia then passes though a brine cooler. Brine is simply the salt, of any substance, dissolved in water. The ammonia chills the brine and the brine then chills the unit (5). The ammonia then passes through the evaporator where it returns to gaseous form. The ammonia then proceeds to the absorber. Here, the evaporated ammonia is dissolved into water. After the ammonia is absorbed, the liquid is now strong and the cycle can begin again. A pump draws off the strong liquid, and discharges it to the generator where the process starts over (6).

gas cools down if it expands suddenly.\n\nsimilar principle is used in AC and refrigerators.

I have a heat pump system for my shop and my wife's craft room. My shop is on the first floor and her room is on the second floor. The HVAC contractor installed one outdoor compressor and one air handler. There are electrically controlled dampers in the supply and return air from each room. There are two thermostats and a microprocessor. The microprocessor controls the dampers and directs the heating (or cooling) to which ever room is calling for it.

I will assume the refrigerant is Freon, with a boiling point of -40F. When the refrigerant condenses, as in goes from gas to liquid, it assumes a lower state of energy, therefore it must give off energy, in the form of heat, thus the air would increase in temperature. This occurs in the condensor of an air conditioner, the part that is OUTSIDE your house.\nInside your house, the refrigerant BOILS in an evaporator (at -40F) which requires heat INPUT, which is taken from the surrounding air, thus COOLING your house. These events combined are called a Carnot Cycle

1. its kinetic energy can be used\n2. It can transport heat.\n3. It's a cooling medium

Usually, when something is cannabilized, parts are taken off of it to fix other products that use the same components.  So, if I had a bad refridgerator with spare parts on to fix another not-so bad fridge, I'd cannibalize parts off of one to fix another.

A still works by taking advantage of the different boiling points for various liquids. For instance, alcohol boils at a lower temperature than water; therefore, you can heat a mixture of alcohol and water and the alcohol will tend to boil first. If you then condense the alcohol vapors, you have made a separation.\n\nThis is an over simplification because even with the alcohol as it vaporizes, some of the water also vaporizes. To make a purer product, you must repeat the process many times. A special column called a fractional distillation column permits you to make a nearly perfect separation

Fill the 5 litre jar with water and pour it into the 3 litre jar. what is left over is 2litre exactly. do this twice and you have 4litres.

1) fill the 3L bucket\n2) pour the 3L bucket into the 5L bucket\n3) fill the 3L bucket\n4) pour the 3L bucket into the 5L bucket until it's full (now you have 1L in the 3L bucket because the 5L bucket had 3L already and room for 2L more)\n5) empty the 5L bucket\n6) pour the 1L from the 3L bucket into the 5L bucket\n7) fill the 3L bucket\n8) add the 3L bucket's water to the 1L of water in the 5L bucket\n9) mop up water

It's difficult to explain without diagrams.\n\nFirst you have an air supply at about 20 psi that flows through a restrictor and a small nozzle the same size as the restrictor. There is a flapper, a small piece of metal that covers the nozzle and controls the backpressure between the nozzle and the restrictor. The pressure between the restrictor and the nozzle is controlled between 20 and 100KPa (3 to 15psi) by the position of the flapper. The position of the flapper is controlled by the input current (usuall y 4 to 20mA of 1 to 5V). Thus the input signal varies the pressure out. I havent seen any links but I will look

What is this condenser's service? Refrigerant, steam, other? Do you need any sub-cooling.\n\nMaterials for the tubes or fins have very little to do with the over all heat transfer rate. Air flow rate and velocity inside the tube have a bigger impact. \n\nIf you do not need any sub-cooling, then having a configuration that will get the condensed liquid out of the condenser so more surface is exposed to the condensing process is important.\n\nOne important thing that is overlooked many times is air recirculation. Having a forced draft arrangement where the fans push the air across the condenser seems at first to be the most economical arrangement but in fact an induced draft arrangement where the air is pulled across the tubes and then discharged by the fans minimizes an air recirculation and actually results in better performance. You should note that most air conditioning condensers use this principle.

Every one seems to have it right, it's just a basic pump , it pumps blood around the system, like a central heating system ,  nothing really very clever about it, all you have to do now is explain what a Central heating system is all about. Good luck !!.

All of them acts in cools the air in a household refrigerator, refrigerant gas (e,g Freon, ammonia,..etc) compressed through compressor and evaporated , and during that circle air cools and heat transfer occur.

The statement is that no cyclic process is possible that does nothing but transfer heat from a cold body to a hot one. In my understanding the key words are "nothing but". To keep a heat pump system working energy (work) needs to be added. In practical heat pumps gas (refrigerant) is compressed, condensed, expanded and evaporated. In compression is where energy is added.\n\nYou can also think of a heat pump as an air conditioned system to cool your neighborhood, just be aware that this "image" has its limitations when you are designing the real thing.
