[0101] Such as figure 1 As shown, this embodiment discloses a heating furnace, which includes a heating furnace body 1, a heating water channel 2, a domestic water channel 3, a heat exchanger 4 and a controller, the heating water channel 2 and the heat exchanger 4 The heat source cavity is connected, and the domestic water channel 3 is connected with the heat exchange cavity of the heat exchanger 4 . The heat exchange efficiency of heat exchanger 4 can be regulated by following heat exchanger control system, and the control system of this heat exchanger is used for regulating the heat exchange efficiency of heat exchanger, and this control system comprises heat exchanger and control The controller is connected with the heat exchanger, and the heat exchanger is used for heat exchange between the heat source fluid and the heat exchange fluid. The water in the heating water channel 2 is driven to circulate in the pipeline by the water pump 5 and heated in the heating furnace bod...

Embodiment 2

[0136] Such as Figure 8-9 As shown, the heat exchanger body 100 of this embodiment is substantially the same as that of Embodiment 1, except that the driving mechanism for controlling the circumferential movement of the sealing member 300 in the first fluid channel 101 is different. The driving mechanism in this embodiment includes an electromagnetic attraction mechanism 400 and a valve stem 401 , one end of the valve stem 401 is connected to the seal 300 , and the other end of the valve stem 401 is connected to the electromagnetic attraction mechanism 400 .

[0137] The axial movement of the sealing member 300 in the first fluid channel 101 is controlled by the electromagnetic attraction mechanism 400 , and the structure is simple. During specific control, the magnitude and direction of the magnetic force are changed by changing the magnitude and direction of the current flowing through the electromagnetic coil inside the electromagnetic attraction mechanism 400 , thereby dr...

Embodiment 3

[0139] The heat exchanger body 100 of the plate heat exchanger of this embodiment is substantially the same as that of Embodiment 1, except that in this embodiment, the heat exchange efficiency of the plate heat exchanger is changed by changing the heat source fluid flowing into the heat exchanger. The flow is adjusted.

[0140] Such as figure 2 , image 3 , Figure 10 and Figure 11 Shown is a plate heat exchanger of this embodiment, which includes a heat exchanger body 100 , a seal 300 and a driving mechanism for driving the seal 300 to rotate. The heat exchanger body 100 includes a plurality of first heat exchange plates 110, a plurality of second heat exchange plates 120 and a housing 130, the first heat exchange plates 110 and the second heat exchange plates 120 are arranged at intervals in the housing 130, the second The sides of one heat exchange plate 110 and the second heat exchange plate 120 have a first groove 115 and a second groove 125 respectively, and the t...

Abstract

The invention discloses a control system of a heat exchanger, a heating furnace and a water outlet temperature control method of the heating furnace. The control system of the heat exchanger is used for adjusting the heat exchange efficiency of the heat exchanger; the heat exchanger is used for conducting heat exchange between heat source fluid and heat exchange fluid; a controller is used for obtaining the temperature value and flow of the heat source fluid before and after the heat source fluid flows through the heat exchanger, the flow of the heat exchange fluid flowing through the heat exchanger, the initial temperature value before the heat exchange fluid flows into the heat exchanger and the preset outflow temperature value; and the controller is used for calculating the circulation heat load of the heat source fluid and the required heat load of the heat exchange fluid according to a formula and judging whether the heat exchange efficiency of the heat exchanger is adjusted or not according to the minimum work heat load and the required heat load of the heat source fluid. According to the control system of the heat exchanger, the heat exchange efficiency of the heat exchanger is adjusted by obtaining various parameter values in a heat exchange system, a user can obtain hot water with the required temperature, and the situation that the water outlet temperature of the hot water is higher than the temperature set by the user is avoided.

Description

technical field [0001] The invention relates to a control system of a heat exchanger, a heating furnace and a method for controlling the outlet water temperature. Background technique [0002] In the traditional plate-replacement dual-purpose heating and hot water boiler, its function is to switch the water circuit of the cycle according to the user's needs. When heating, the three-way valve pushes the valve stem to the bottom through the action of the motor to open the large circulation loop, so the heating water with temperature can enter the heating end (floor heating or radiator) to radiate and heat the room; when there is domestic heat When the water is in demand, once the main controller detects the domestic water flow signal, it will immediately control the motor to return to the initial position, so that the valve stem will return to the top under the action of the tension of the spring. At this time, the large circulation loop is closed, and the small circulation lo...
