How Laws Of Thermodynamics Control Heat Pumps

Heat pumps are appliances that are used to transfer power from one point known as the source to another point referred to as a sink. Normally a heat source has a greater temperature as compared to an heat sink. Even though some air conditioners can be theoretically termed as heat pumps, it largely includes a group of devices that can do more that refrigeration.

In the working of this device, part of the power has to be changed into another different form of energy before it can appear again as thermal energy at the sink. Mechanical work or other source that produces energy thermodynamically is used in transferring of the required power from its point of origin to the desired termination point.

In the real scientific sense, this device is not involved in the heat movement, since the heat cannot move from a region of low temperature to a region a region of high temperature. This actually means that the name of this apparatus cannot be literally used when referring to the work it performs. The laws of thermodynamics are always obeyed by the machine.

The fluid normally flows at the external region of the region that is to be thermally controlled. This is basically where the condensers and condensers are placed as opposed to the evaporators that are normally located internally. A heat pump differs from an air conditioner in that, it has a reversing valve. It is this component that makes it possible for the machine to transfer the heat in either way.

A pump can be preferred when increasing the temperature levels of a given place or environment since of their high level of efficiency. This is because it utilizes some power from the commercial sources and the external surroundings. The devices are known to be utilized in the cooler regions for the purposes on increasing the surrounding heat levels.

In the same way, the liquid is required to have an adequately low heat on the area of expanding since flowing of heat from a region with lower temperature to the liquid is impossible. This means that that this liquid is required to have a lower heat than that present in the heat exchanger. Also the pressure gradient should be high enough to allow condensation on the region of high temperature as well as evaporation at the point of lower temperature.

Most of the devices are made in such a way that they can be able to work in either direction without any problem. For it to achieve this, the design of a condenser and the evaporator has to be given some special emphasis. In addition to it, the valve is turned the other way round. The heat pumps normally used in climates that have fluctuations of temperatures from one season to another.
