Abstract

A heat-pump arrangement with an installation consisting of a motor and a compressor of trochoidal type construction adapted to conditions of heat pump systems to have the smallest structural size and nominal heat spread arranged between heat storage or accumulator and outlet large heat quantities per time unit passing therethrough as well as also being able to operate economically at low partial load range of operation. An intermediate part is provided between a motor and a compressor. Two annular chambers are arranged parallel and axially next to each other. An annular chamber is located toward the motor. The middle part has a dual-arc troichoidal-shaped casing or mantle runway and two side parts which have an eccentric shaft passing therethrough at right angles to the side parts; a triangular piston rotates upon an eccentric of the eccentric shaft for the motor and a compressor of the same type of construction is also arranged on the same eccentric shaft shared in common with the motor. The pistons and the eccentrics of the two machines balance or counterbalance each other during corresponding displacement of piston positioning so that a considerable shortening of the axial struc…
