Domestic or industrial building heater - effecting mechanical operations necessary for thermodynamic cycle almost reversibly, with high efficiency

摘要

An installation for heating buildings used as dwellings or industrially makes use of a gas which is in contact alternately with a cold source and a hot source by means of inlet and outlet heat exchangers and a compressor which circulates the gas. The gas describes a thermodynamic cycle in a closed circuit. The exchangers connects points of the circuit situated at different heights in a natural or artificial gravity field. The gas has a lower specific heat capacity than the air and undergoes substantially isothermal press. changes. It exchanges heat with a liquefiable fluid of high latent heat. Typically, the gas is argon and the fluid is pentane. The installation operates in a cycle which approaches closely thermodynamic reversibility. It is simpler and is more efficient than existing installations using a fluid which changes its physical state, and rotary machines, in several stages, of low efficiency because of thermodynamic irreversibility.
