Embodiment 1

[0041] A heat recovery air conditioning system using cooling water, refer to figure 1 , including an air supply device 1 , a condensation device 2 , a heat recovery device 3 and a heat exchange device 4 . Air blower 1 comprises installation housing 12 and fan 11, and installation housing 12 has air inlet 123 and air outlet 124, and fan 11 is arranged in the installation housing 12 to drive the air in the installation housing 12 to form from air inlet 123 to The airflow flowing through the air outlet 124.

[0042] The heat exchange device 4 includes a first heat conduction element 41 and a second heat conduction element 42, the first heat conduction element 41 is connected to the condensation device 2, the second heat conduction element 42 is connected to the heat recovery device 3, the first heat conduction element 41 and the second heat conduction element 42 are closely attached to each other and fixedly connected so that the heat recovery device 3 and the condensing device ...

Embodiment 2

[0048] The difference between embodiment 2 and embodiment 1 is that, with reference to image 3 A heater 34 is provided between the circulating water pump 32 and the second heat conducting member 42 without the cooler 33, and the heater 34 heats the cooling water in the heating circuit, so that the cooling water has higher heat. Compared with Example 1, the upper and lower limits of temperature control in this example are higher.

Embodiment 3

[0050] The difference between embodiment 3 and embodiment 1 is that, referring to Figure 4 A heater 34 is also provided between the circulating water pump 32 and the second heat conducting member 42, the cooler 33 and the heater 34 are sequentially connected in series between the circulating water pump 32 and the second heat conducting member 42 through the connecting pipe, and the heater 34 can be controlled The cooling water in the thermal circuit is heated. In this embodiment, it should be noted that the heater 34 and the cooler 33 are not used at the same time, so as to avoid energy waste caused by the heater 34 and the cooler 33 working at the same time so that the effects of heating and cooling the cooling water cancel each other out. Compared with Example 1, the upper limit of temperature control in this embodiment is higher and the temperature control range is wider; compared with Example 2, the lower limit of temperature control in this embodiment is lower and the te...
