A heat exchanger is a system used to transfer heat between a source and a working fluid.Heat exchangers are used in both cooling and heating processes. Heat exchangers are devices designed to transfer heat between fluids with different temperatures. Transferring heat from one medium to another (in this case, from potable water to antifreeze via the heat exchanger) costs BTUs. As mentioned earlier, the exchanger needs a defrost control to keep ice from forming. Figure 4 Heat Transfer in a Double Pipe Heat Exchanger. In Order to increase the heat transfer area, fins are also attached periphery of tubes. parallel-flow arrangement. It is used to capture or dissipate heat to or from the ground. 4. The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance, and the specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material. Heat Pipe Limits. These heat exchangers are generally designed, inspected, and tested as per EN-ISO 13706. Crossflow, parallel flow, and counterflow heat exchanger configurations are three examples. The heat transferring process based on the type of heat exchanger can be gas to gas, liquid to gas, or liquid to liquid. These currents circulate throughout the body of the appliance and across its heating element.This process, following the principle of thermal conduction, heats up the air, reducing its density relative to colder air and causing it to rise. A heat exchanger system using antifreeze can protect the radiant heating system down to -60 below zero. As the name of this heat exchanger represents that it uses two pipes to exchange heat between two fluids. Before using a Plate Heat Exchanger sizing calculator the principle that heat will always leave the warmer fluid and that heat energy will be transferred to the colder fluid must be understood. This is a sort of heat exchanger because the heat from one fluid (the hot water in the pipe) is being given to another fluid (the cold air in the room) without the two fluids mixing. The simplest heat exchanger is one for which the hot and cold fluids move in the same or opposite directions. This exchanging is conducted through a solid separator preventing direct contact of these fluids. The floating head exchanger is, therefore, the best heat exchanger in terms of efficiency and maintenance, but naturally comes at a higher cost.
