Embodiment

[0029] Implementation example: such as Figure 1-Figure 2 A temperature-controllable air heat recovery device is shown, the device includes a fresh air side heat pipe group 1, an exhaust side heat pipe group 2, a thermopile 3, a heat pipe thermopile connecting sleeve 4, an exhaust side temperature probe 12, a fresh air Side temperature probe 14 and current controller 13;

[0030] The heat pipe group 1 on the fresh air side and the heat pipe group 2 on the exhaust side are connected to the thermopile 3 through the heat pipe thermopile sleeve 4 respectively; The input current of 3 is controlled by the current controller 13; the current controller 13 is connected with the first temperature probe 12 and the second temperature probe 14; the first temperature probe is installed on the fresh air side heat pipe group; the second temperature probe is installed on the exhaust side heat pipe Group.

Embodiment 2

[0041] This embodiment discloses a control method of a temperature-controllable air heat recovery device, which includes the following steps:

[0042] In the first step, the user sets the temperature value as T0, and the temperature measured by the temperature probe on the exhaust side is T1; the temperature measured by the temperature probe on the fresh air side is T2;

[0043] The second step is to determine the output current value by comparing the phase difference between T0, T1 and T2; if |T2-T0|T2 is established, the current controller will output a reverse current. If T1>T2 is not established, the current controller will output a forward current; ε is any small value. , reflecting the control accuracy;

[0044] The third step is to determine the output current value by comparing the phase difference between T0 and T1; if |T1-T0|<ε is established, the current controller maintains the current current value; if |T1-T0|<ε If it is not established, judge according to the cu...

Abstract

The invention discloses a temperature-controllable air heat recovery device and a control method thereof, and belongs to the field of building energy saving and ventilation and air exchange. The air heat recovery device adopts a heat pipe and thermopile integrated technology, the heat recovery efficiency of fresh air of a single heat pipe is reinforced, through the invented heat pipe and thermopile combined mode, tightness is improved, heat transfer is reinforced, and meanwhile, the temperature control function can be achieved through the corresponding control method. The temperature-controllable air heat recovery device comprises a fresh air side heat pipe set (1), an exhaust side heat pipe set (2), a thermopile (3), a heat pipe and thermopile connecting sleeve head (4) and a current controller (13). In winter, heat of exhausted air is recovered to heat the fresh air, and in summer, the cooling capacity of the exhausted air is recovered to cool the fresh air. The current controller (13) can regulate the refrigerating capacity or the heating capacity of a heat exchange core, and thus the set temperature is maintained. The air heat recovery device adopts the heat pipe and thermopileintegrated technology, the size is small, the temperature can be controlled, the air heat recovery device can be applied to a domestic window-type fresh air ventilator, the indoor attractiveness is not affected after mounting, and the good development prospects are achieved.

Description

technical field [0001] The invention belongs to the field of building energy saving and ventilation, and relates to a temperature-controllable air heat recovery device and a control method thereof. Background technique [0002] As people's requirements for the living environment are getting higher and higher, indoor air quality has become an important factor in determining the living environment. Under such a trend, the use of fresh air fans is becoming more and more popular. There are two types of fresh air fans on the market, one with heat recovery function and the other without heat recovery function. [0003] Household fresh air fans without heat recovery will bring the indoor cold or heat to the outside while ventilating, which will cause a waste of energy. Most of the internal heat exchange cores of fresh air fans with heat recovery function are plate-type and large in size, which will increase the size of the fresh air fan and greatly affect the indoor appearance. ...
