A partition is provided at the middle end of the layered arrangement, and working chambers are opened at the upper and lower ends of the partition and in the working box. A water tank is fixedly provided on the working chamber on the lower side, and the water tank contains insulation liquid. The water tank is provided with a connecting pipe extending outward and penetrating through the working box. The water tank is connected with heat-absorbing fins evenly distributed on the left and right, and the heat-absorbing fins are L-shaped and abut against the upper and rear end parts of the heater. The front end of the water tank is connected and fixed with two groups of left-right symmetrical heat exchange tubes, and the heat exchange tubes extend forward and downward and are arranged in the two exchange ends.

[0006] The beneficial effects of the utility model are:

[0007] Through the insulation liquid in the water tank, when the heater is in normal working condition, the heat-absorbing fins and the heat exchange tubes absorb the excess heat generated by the heater and the heat in different hot gases, so that the temperature of the liquid in the water tank rises. In the subsequent working process, the heater stops working, and the rotating fan mechanism is used to make the air contact with the heat exchange tube and heat up for insulation work. The heating work can continue for a period of time, reducing energy consumption and improving energy-saving effects.

[0008] Through the water tank and the heat exchange tube, the external room temperature is always kept at a relatively suitable temperature, which can realize the function of long-term heating, increase the interval between the start and stop time of the heater, and improve the service life of the heater.

[0022] Reference Figure 1-Figure 8 According to an embodiment of the utility model, a long-term HVAC energy-saving device includes a working box 10, the front end of the working box 10 is provided with two air inlet ends 11 and air outlet ends 12 distributed up and down, the left and right ends of the air outlet end 12 are provided with exchange ends 13, the air inlet end 11 and the air outlet end 12 are connected with a filter screen 14, the air inlet end 11 and the air outlet end 12 are connected with a rotating fan mechanism 15, the upper rotating fan mechanism 15 is located at the rear end of the filter screen 14, the rear end of the lower filter screen 14 is sequentially provided with a shutter box 16 and a rotating fan mechanism 15, and the rear end of the rotating fan mechanism 15 at the lower end is provided with a heater 17, the working box 10 is provided with a working box 10, and ... The working box 10 is provided with a partition at the middle end of the upper and lower layers. The upper and lower ends of the partition are provided with working chambers 23 in the working box 10. A water tank 18 is fixed on the working chamber 23 at the lower side. The water tank 18 contains a heat preservation liquid. The water tank 18 is provided with a connecting pipe extending outward and penetrating the working box 10. The water tank 18 is connected with heat absorbing fins 21 evenly distributed on the left and right. The heat absorbing fins 21 are arranged in an L shape and abut against the upper and rear ends of the heater 17. The front end of the water tank 18 is connected and fixed with two groups of left-right symmetrical heat exchange tubes 22.
