The duty of a heat exchanger can be defined in an easy way as "The amount of heat exchanged from a fluid at a higher temperature to the fluid at lower temperature in unit time by a heat exchanger is called its duty"
Cooling towers are also known as an air conditioner's radiator unit. A mist cooling system are fans that have water dripping in front of them in boxed units. These are still used in some parts of the developing world in the absence of air conditioners.
A shell and tube heat exchanger will have two fluids flowing through continuously. The fluid in the tube will typically be the important fluid, the fluid you are trying to heat or cool. The fluid in the shell will then be the fluid that is heating or cooling the the fluid in the tube.Take a steam heat exchanger for example. Steam condenses in shell, while the the fluid in the tube picks up the heat from the steam. And in a perfectly efficient steam heat exchanger, all the heat lost from the steam would be recovered by the liquid in the tube.But nothing is perfect. A little bit of the steam's heat makes the outer shell hot, and that in turn heats the room. Heat is lost from the steam into places other than the fluid in the tube. So efficiency measures how much of the heat lost by the shell fluid makes it into the tube fluid.Efficiency (for heating) = Amount of Heat that went toward heating the fluid divided by the amount of heat that was lost by the heating fluid.So an efficiency of 1 is perfect. For every 1 unit of heat absorbed by the tube fluid, we spent 1 unit of heat from the fluid in the shell fluid.And if the efficiency is 0.9, or 90%, then for every 10 units of heat that the shell fluid lost, the tube fluid gained 9.Sometimes efficiencies are as bad as 40%. In this case for every 10 units of heat lost by the heating fluid, 4 units are gained by the fluid.A slightly different definition of efficiency applies to cooling:Efficiency = Amount of heat lost by the tube fluid divided by the amount of heat gained by the shell fluid.Same story, if the shell fluid gains 5 units of heat, and tube fluid loses 4, then the efficiency is 0.8 or 80%.
A working dehumidifier will not cause a fire if it is working and connected properly. They are no more apt to cause a fire than any other electrical appliance. If the unit overheats it will shut off on the internal overload protection. If it draws to much electricity from the outlet, it will trip the circuit breaker. Those items will prevent a fire. A dehumidifier does use a fair amount of current, so the plug will get warm (not hot), to the touch. If the unit is working, stop worrying about it. It will be fine. Lightning causes many more home fires than dehumidifiers.
why is it important to have drainage for the outdoor unit

One major benefit of a heat exchanger is that it quickly transfers heat from one medium to another such as an air conditioning unit or a space heater.
yes
Your really are better off replacing the whole unit, there was a reason for the heat exchanger to have cracked or malfunction, ether for age or or a mechanical anomaly , you may have not addressed, as of yet.
There should be only one blower to move the air. The unit will have a coil for cooling and a heat exchanger.
The HMU unit at refinery works by using the Heat Exchanger Reformer technology to help produce 99.9% pure Hydrogen gas.
Yes, you can replace the heat exchanger in the unit, but will cost approximately 1/2 of the price of installing a brand new unit. The exchanger should only be replaced if the unit is less than 6-7 years old and in excellent shape, especially the combustion chamber lining. Matt - Flamborough Gas and Oil.
A calorifer is a type of radiator that heats a room by circulating hot water through its pipes. A heat exchanger is a device that transfers heat from one fluid to another without the fluids mixing, typically used in heating, cooling, or refrigeration systems. The key difference is that calorifers are specifically designed for room heating, while heat exchangers can be used for various heat transfer applications.
A General Electric dehumidifier uses a sealed unit that does not have any way for you to add Freon to the unit. If you want to add Freon, you have to first install saddle valves to the dehumidifier.
Plate heat exchangers are used in combination boilers, also sometimes referred to a 'combi-boilers'. The plate heat exchanger is found inside the hot water section and uses metal plates to move heat between two fluids.
You have to add a valve to the dehumidifier in order to put Freon in a GE dehumidifier. The reason you have to add the valve is because dehumidifiers uses a sealed unit.
There are actually many types of plate heat exchangers, and the YOJO brand has introduced brazed plate heat exchangers and gasket plate heat exchangers. Today is the home of brazed heat exchangers.Brazed plate heat exchangers have no headers, tie rods or sealing gaskets, and the plates are brazed at a temperature of 1100 ° C. During the assembly stage, a piece of brazing material (usually copper, and nickel) is placed between the two plates, the package is compressed, and then baked for several hour.BPHE is more compact and lighter, and the brazing material has the functions of both washer and frame. The intersection between the corrugations of the two coupling plates forms a dense network of contact points, which impart pressure tightness and generate vortex flow, thereby improving heat exchange. In this way, even at low nominal input speeds, the turbulence of the fluid is high, and for low flow rates, the fluid flows from laminar to turbulent.
