Air heat pump indispensable equipment (Figure)
As we all know, the heat pump is the use of reverse Carnot cycle principle of work, refrigeration and heating is only the working temperature range is not the same, the main components of the heat pump system: evaporator, condenser, compressor, expansion valve, the control unit. Controlled by the central control unit to form a thermodynamic cycle compressor operation, the heat sent to the end of the job on demand, to achieve the purpose of cooling or heating, energy consumption is only driven compressor to form the power cycle thermodynamic. Air source heat pump components Equipment Heat pump at work, the energy stored in the ambient medium QA absorbed in the evaporator; it itself consumes part of the energy, the compressor power consumption QB; through the working fluid circulation system in the condenser to put Heat QC, QC = QA + QB, it can be seen that the heat pump output energy for the compressor work QB and heat pump heat absorbed from the environment QA; the heating coefficient is εh = QC / QB, we can see that εh value Constant greater than 1. Therefore, the use of heat pump technology can save a lot of electricity.
