Abstract
The invention relates to the refrigerant circuit (1) of a heat pump. The refrigerant circuit (1) contains a compressor (2), a liquefier (3) and an evaporator (4). Between the liquefier (3) and the evaporator (4), a thermostatically adjustable expansion valve (5) is arranged. In order to prevent adjustment fluctuations, a further expansion device (7) is arranged parallel to the expansion valve (5). The expansion device (7) advantageously consists of a choke capillary tube. The maximum effective throughflow cross-section of the expansion valve (5) is reduced in favour of the effective throughflow cross- section of the expansion device (7). <IMAGE>
