<p>1. A process for the operation of a two-condition heating installation, comprising the following features : a) into a heating circuit which conducts a liquid heat carrier and which contains a heat pump (1), a further heat source (2), a first multi-path mixer (3) which is connected to the heat pump (1) and the further heat source (2), an outgoing pipeline (7) which extends from the first multi-path mixer (3) to a second multi-path mixer (8), and an outgoing leg (9) which commences from the second multi-path mixer (8), the further heat source (2) is inserted when a temperature difference between the outgoing pipeline (7) and the outgoing leg (9), which is established by a differential temperature regulator (16) through two temperature sensors (14, 15), assumes a predetermined value ; characterised by the following features : b) the heat pump (1) is switched on at a lower value of the temperature difference ; c) the further heat source (2) is switched on when, at the end of a predetermined time interval after the switching-on of the heat pump (1), the lower value of the temperature difference has not yet been exceeded ; d) after the switching on of the further heat source (2), the flow from ther further heat source (2) into the outgoing pipeline (7) is increased in the first multi-path mixer (3) until the lower value of the temperature difference is exceeded ; e) after an upper value of the temperature difference is exceeded, which takes place due to a supply of heat, or due to a change in the heat requirement, the flow in the first multi-path mixer from the further heat source (2) into the outgoing pipeline (2) is reduced until the temperature difference falls below the upper value ; f) at the end of a predetermined time interval the further heat source (2) is switched-off when the first multi-path mixer (3) has reached its "off" position ; g) the heat pump (1) is switched-off when the first multi-path mixer (3) assumes its "off" position and the lower value of the temperature difference is exceeded.</p> |
