how is the heat pump air conditioning work?

A heat pump is like a conventional air conditioner except it also can provide heat in winter. In the summer, the heat pump collects heat from the house and expels it outside. In the winter, the heat pump extracts heat from outside air and circulates it inside the house. The heat pump works best when the outdoor temperature is above freezing. Below that, supplementary heat often is needed. A heat pump can save 30 to 60 percent less energy to supply the same heat when compared to an electric furnace with a resistance heating element.\n\nCOOLING CYCLE -- Refrigerant passes through the indoor coil, evaporating from a liquid to a vapor. As the liquid evaporates, it absorbs heat, cooling the air around the coil. An indoor fan pushes this cooled air through ducts inside the house. Meanwhile, the vaporized refrigerant laden with heat, passes through a compressor which compresses the vapor, raising its temperature and pressure. The reversing valve directs the flow of hot, high pressure vapor to the outdoor coil where the heat released during condensation is fanned into the outdoor air, and the cycle begins again.\n\nHEATING CYCLE -- Note that the slide inside the reversing valve has shifted, causing the refrigerant flow to reverse. Liquid refrigerant now flows to the outdoor coil picking up heat as it evaporates into a low pressure vapor. The vapor travels through the compressor where it is compressed into a hot, high pressure vapor, then is directed by the reversing valve to the indoor coil. The vapor turns into liquid as it passes through the indoor coil, releasing heat that is pushed through the ducts by the indoor fan.

It may depend on the source and use of heat.  An electric heater would heat the air locally permitting the air to hold more moisture while perhaps drying some surfaces, but would not remove any moisture.  An existing circulation air heating system placed into service by opening duct vents would supply new dry air forcing moist air to move on perhaps returning to the furnace.  The basement may be damp because moisture penetrates the walls (possibly through cracks).  Therefore a dehumidifier or a central heating system may perform equally well compared to an electric heater unless the electrically heated warmed air is free to leave the area (perhaps rising up the stairs?).

An Air conditioning system normally just cools the air in the room (or vehicle) in which it is fitted.\n\nIt works like a refrigerator but expels the warm air to atmosphere rather than the room.\n\nThe disadvantage of the normal system is that it dries the air.\n\nSome systems can apply heat too so that a controlled temperature can be selected from a much wider range, and more sophisticated systems can maintain a desired humidity.

about heating maching bring a thick wire and wrap it around a spoon then the tips connect them into electric source (big one) dont do it alone it gets really hot ...ok\nabout the cooling machine i dont know

sure- it's easy- the refrigeration system moves heat out of one area into another- and simple experiment for you to do, is take a can of pressurized spray whatever, and spray it- can gets cold from reduction in pressure, allowing molecules space to "slow down" because they quit "bumping" from being in a tight spot- making room for more heat- or "making" cold- with me so far? now just picture a system with a pump that packs the gas molecules tightly together, and on the other end has a spot for them to expand (making room for more heat)and then runs the "heated" expanded gas through a radiator (heat comes out) and then gets compressed (packed) again- round and round "absorbs heat- moves heat- loses heat" \n hope this helps- if you really need more help email me through answers and I can provide pictures of how it works.

It increases the temperature briefly.  Then entropy takes over and it assumes the ambient air temperature.

The basis of most (more than 95%) refrigeration systems is the ' vapour compression cycle". The media (vapour) is Refrigerant (hydrochlorofluorocarbons - HCFC or hydrofluorocarbons - HFC) or freon which is non-toxic, non-explosive and non-corrosive. These Refrigerants have a boiling point of aprox. Minus 40°C which means that even if the air (outside or inside) temperature is as low as minus 39°C it still has heat to be absorbed by refrigerants. \n\nThe vapour compression cycle requires four components:\n\n1) The compressor: To raise the pressure of low-pressure low temperature gas to high-pressure high temperature gas. There are many types of compressors; the most common are Reciprocating, Rotary, Scroll, Screw and Centrifugal. \n2) The Condenser: To change the state of high-pressure, high temperature gas to high-pressure, high temperature LIQUID. This is achieved by passing ambient air (known as air-cooled) or water (known as water-cooled) over the condenser tubes. \n3) The Expansion Device: The purpose of the device is to change the state of the refrigerant from high-pressure, high temperature liquid to low pressure low temperature saturated liquid. This is achieved by passing the liquid through an orifice. \n4) The Evaporator: To absorb the heat from room air or water, which in the case of a chiller is circulated around the evaporator coil. This will change the state of low-pressure, low temperature saturated liquid to low pressure, low/medium temperature gas. \nThese components are common to the vast majority of domestic refrigerators and appear in slightly different forms in 95% of air conditioning and refrigeration systems, Domestic, commercial or industrial. This vapour compression cycle if reversed (condenser becomes evaporator and visa versa) can now absorb heat from outside and transfer it to inside, hence saving energy. This is called Reverse Cycle Heat Pump. Energy savings can be as high as 4 to 1 (for every kW input we get 4 kW output).

I presume you're asking about an air conditioner.\n\nAir conditioners are rated in terms of the equivalent cooling capacity of tons of ice.   So, a one ton air conditioner can cool as much as a ton (2000 lbs) of ice melting in a 24 hour period.   A home air conditioning unit is typically in the range of 1-3 tons of capacity.  One ton is also equivalent to about 12000 BTUs (British Thermal Units) per hour of cooling.

The absorption refrigerator is a refrigerator that utilizes a heat source to provide the energy needed to drive the cooling system rather than being dependent on electricity to run a compressor. These refrigerators are popular where electricity is unreliable, costly, or unavailable.\n\nThe basic principle of how these refrigerators cool their interior is the same as in conventional compression refrigerators. Both use refrigerant liquids that boil at low temperatures to achieve cooling. A large amount of energy is needed to turn the liquid into gas, and this is absorbed from the surroundings, cooling them. The difference is in how the gas is turned back to liquid to use it again for more cooling. A conventional electric refrigerator uses a pump to compress the gas back to liquid; a gas absorption refrigerator uses another liquid to absorb the gas and then has extra stages to separate the pure refrigerant liquid out again for re-use, this extra part being where the heat source is involved.\n\nVariations exist, but the usual pattern of gas absorption refrigerator uses ammonia as the refrigerant and water as the absorber, with hydrogen gas included to adjust the pressure in the system. The exact mixture and pressure has to be correct to give proper cooling at normal temperatures.\n\nThe cooling system consists of four main parts: the evaporator, absorber, generator and condenser. The evaporator is where chilling happens as the liquid ammonia evaporates, absorbing heat from its surroundings to enable the liquid to turn to gas. The ammonia gas passes on to the absorber, where it dissolves in water. The solution flows down to the generator where the external heat source is used to bubble the ammonia out again. This gas is purified by condensing out water vapour before rising to the main condenser. The condenser has big fins on the outside which let air cool it sufficiently for the ammonia to flow out of the bottom as a liquid again, down into the evaporator.\n\nThe hydrogen plays an interesting part in making this cycle work. Why does the ammonia which turned to liquid in the condenser then evaporate at essentially the same temperature and pressure in the evaporator? Because the evaporator also contains hydrogen gas, and the partial pressures exerted by the two gases mean that the ammonia liquid will evaporate (Dalton's law applies). The hydrogen is present in the absorber too, but is not absorbed as it does not dissolve in the water.\n\nThe ammonia, water and hydrogen system is closed. The water in the absorber is actually a weak solution of ammonia carried out of the generator when the ammonia bubbles out by a "bubble pump" like the pipe of a coffee percolator. There is no other pump in the system, liquids flowing back down under gravity and the gas pressure being the same throughout the system.\n\nThere are other gas absorption refrigerators which use only ammonia and water with a heat source applied intermittently, possibly just once a day. These have a pressure valve between the condenser and evaporator so that the generator and condenser are pressurised when the generator is heated. The liquid ammonia is forced slowly through the valve from the high pressure side into the evaporator where it evaporates in the lower pressure. The pressure differential will last for some time after the heat source is removed, so active cooling occurs for longer than the time the heat is applied. When the pressures have equalised, the ammonia solution from the absorber can flow back into the generator ready for the cycle to start again.

It is thermodynamic concepts. Where the high temperature resorvior heat energy transfer to low temperature resorvior (cool), that process known as absorbtion. It can be both way either heat or cool absorbing system.

Not very well. \n\nIf the ambient temperatures will be in the 30 degree range and below then a heat pump does best with a heat sink such as a underground well to provide heat at high enough level to be economic.

An air conditioner inverter is part of a microprocessor-controlled system to provide more precise temperature control and less on-off compressor cycling. The inverter works in conjunction with a variable-speed motor which drives the compressor. These systems are said to be more efficient at part load than older systems. The references will give you the general idea.

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).

Outside the house you have a condenser unit with a compressor.  The compressor compresses freon gas and that makes it hot.  The condensor then removes the heat and turns the freon into liquid.  That is why the outside unit blows out hot air.  The liquid freon then goes to the evaporator inside the house.  In the evaporator, there is a thing called the thermostatic expansion valve or some capillary tubes (very small).  The liquid freon discharges through the TEV or capillary tubes and when it does, it expands in the presence of the suction from the compressor to form a gas.  As it forms a gas it draws heat from its surroundings to do that.  That is why the evaporator gets cold.  The cold freon gas is then sucked through the coils in the evaporator where it draws heat from the air coming across them back into the compressor, where the compressor compresses the cold gas and it gets hot again, and the cycle repeats itself over and over as the unit runs!
