| (54) | HEAT SUPPLY APPARATUS |
| (57) The present disclosure relates to a heat supply apparatus. The heat supply apparatus
according to the present disclosure comprises: a compressor compressing refrigerant;
a first heat exchanger being connected to the compressor through a refrigerant pipe
and exchanging heat between refrigerant and water; a second heat exchanger being connected
to the compressor through a refrigerant pipe and exchanging heat between refrigerant
and air; and a gas-liquid separator located upstream of the compressor in a refrigerant
flow path and separating introduced refrigerant into gaseous refrigerant and liquid
refrigerant, wherein the gas-liquid separator includes: a housing; and a penetration
pipe passing through one side and the other side of the housing and including an inlet
flow path through which mixed refrigerant flows in and an outlet flow path through
which gaseous refrigerant flows out, wherein the penetration pipe includes: a first
connecting hole formed on a surface and connecting the inlet flow path and the inside
of the housing; a second connecting hole formed on a surface and connecting the outlet
flow path and the inside of the housing; and a separation plate partitioning the inlet
flow path and the outlet flow path.
