ロードヒーテイングシステム。[Claims for Utility Model Registration] (1) In a road heating system that heats a road heater with heat absorbed from air by an air heat exchanger on the heat source side of an air heat source heat pump,
The duct connected to the exhaust port of the subway exhaust tower is equipped with an outside air intake damper that closes and opens according to the ON/OFF of the exhaust fan, and the air outlet of this duct is connected to the heat source side air heat exchanger and the air A road heating system that is equipped with a fan that blows air. (2) The road heating system according to claim (1), characterized in that the air source heat pump is a capacity-controlled heat pump, and a controller is provided for operating the heat pump under capacity control when the exhaust fan is turned on. (3) In a road heating system that heats brine with the heat absorbed from the air by the air heat exchanger on the heat source side of an air source heat pump, and heats the road heater by circulating this brine, The duct connected to the tower's exhaust port closes and closes depending on whether the exhaust fan is turned on or off.
An outside air suction damper that is opened is provided, and the air heat exchanger on the heat source side and a fan for blowing air to this are provided at the air outlet of this duct, and the air heat source heat pump is heated to the temperature of the brine heated by this. A road heating system comprising: a controller that performs ON/OFF control in response to the exhaust fan and increases a set value of a brine temperature for turning on/off the air source heat pump when the exhaust fan is turned on.
