Title:
HEAT-PUMP-TYPE HEATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/140954
Kind Code:
A1
Abstract:
A heat-pump-type heating apparatus, wherein the heating capacity of a heating device (2) is controlled with greater precision according to heating load. A control device (1) for controlling the heating device (2): determines the required heating capacity based on the exterior temperature, a set heating temperature, and the like; causes a compressor (2b) to operate based on the rotation speed for the set heating capacity and controls an expansion valve (2d) so that the discharge temperature of the compressor (2b) reaches a predetermined value; and performs a control so that the outgoing heat-medium-temperature measurement value of the heat medium delivered to the heating terminal is consistent with the outgoing heat-medium-temperature determined value for the heating capacity. Once it has been determined that the outgoing heat-medium-temperature measurement value is consistent with the outgoing heat-medium-temperature determined value, the control device (1) compares the cooling-medium-outlet-temperature measurement value of the heating-medium heat exchanger (2c) measured by a temperature sensor (2f) with a cooling-medium-outlet-temperature stored value according to the determined heating capacity; and, if there is a disparity between the measured value and the stored value, changes the determined heating capacity to eliminate the disparity.
