Title:

HEAT PUMP-TYPE HEATING DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/065309

Kind Code:

A1

Abstract:

The present invention prevents the oil level in a compressor from dropping when starting the compressor. This heat pump-type heating device (1) is provided with: a compressor (10); a heat source-side heat exchanger (11); a refrigerant circuit in which a motor-operated valve (12) and usage side heat exchangers (16A, 16B) are provided; and an outdoor fan (13) for the heat source-side heat exchanger. The usage side heat exchangers are configured to be able to heat, by a refrigerant, a fluid (hot water supply, indoor air) supplied from the outside, and the rotational speed of the outdoor fan when starting the compressor is smaller in cases where the difference between the fluid temperature (62, 63), indoor air temperature) supplied to the usage side heat exchangers and the outside air temperature (67) is equal to or greater than a prescribed temperature difference than in cases where the difference between the fluid temperature supplied to the usage side heat exchangers and the outside air temperature are less than the prescribed temperature difference.
