Description

Technical Field

[0001] The utility model belongs to the technical field of heating, and in particular relates to a heating system using a heating furnace. Background Art

[0002] With the development of society and the continuous improvement of living standards, in order to maintain a relatively comfortable indoor temperature in cold weather, people generally install heating systems indoors to maintain the indoor temperature of each room.

[0003] Patent document number CN208871702U discloses a heating device, including a heat source, a heat preservation water tank, a circulating water pump, and a room. The heat source, the heat preservation water tank, and the circulating water pump are connected in series in sequence through a water supply pipe and are respectively arranged outside the room. A sleeping cabin and an indoor heat dissipation device are respectively arranged inside the room. An indoor heat dissipation device is arranged inside the sleeping cabin. The indoor heat dissipation device and the indoor heat dissipation device are respectively connected to the circulating water pump and the heat preservation water tank through a water supply pipe and a return pipe. The heat preservation water tank is connected to the heat source through a return pipe. The heat dissipation temperature of the indoor heat dissipation device is controlled by heating the heat transfer medium with the heat source. Temperature is achieved. When the heating temperature of the heat source for the heat-conducting medium is high, the heat dissipation temperature of the indoor heat dissipation device is high. When the heating temperature of the heat source for the heat-conducting medium is low, the heat dissipation temperature of the indoor heat dissipation device is low. The problem is that, in the heating device with the above structure, the heat dissipation temperature of the indoor heat dissipation device is constant without human operation and adjustment. When the internal temperature of the room is too high or too low, the indoor heat dissipation device cannot adjust its heat dissipation temperature in time, resulting in the inability to maintain a comfortable temperature inside the room. People feel poorly when staying inside the room, which affects people's use experience of the heating device.
