Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a triple co-generation system 100 according to an embodiment of the present invention.
The triple co-generation system 100 provided by the embodiment of the invention comprises an air conditioning system 110, a floor heating system 130 and a domestic water system 150, wherein the air conditioning system 110 is used for regulating the temperature of indoor air, the floor heating system 130 is used for heating an indoor floor, and the domestic water system 150 is used for supplying hot water. The triple co-generation system 100 provided by the embodiment can protect the fluorine water heat exchanger 121 from being corroded by the running water, and the service life of the fluorine water heat exchanger 121 is prolonged, so that the safety of the triple co-generation system 100 is higher.
The air conditioning system 110 is provided with a refrigerant pipeline 111, a refrigerant flows in the refrigerant pipeline 111, the floor heating system 130 is provided with a closed floor heating pipeline 131, and the domestic water system 150 is provided with a domestic water pipeline 151 externally connected with living water sources such as tap water. The refrigerant pipeline 111 exchanges heat with the floor heating pipeline 131 through the fluorine water heat exchanger 121, and the domestic water pipeline 151 exchanges heat with the floor heating pipeline 131 through the water channel heat exchanger 141.
It can be understood that, in practical application, the triple co-generation system 100 provided in this embodiment can realize the complete recycling of condensation heat in the mode of cooling and hot water supply, and the heat stored in the refrigerant pipeline 111 is transferred to the floor heating pipeline 131 through the fluorine water heat exchanger 121, so as to heat the heating water in the floor heating pipeline 131. After the heating water exchanges heat with the fluorine water heat exchanger 121 for the first time, the heating water exchanges heat with the domestic water in the domestic water pipeline 151 for the second time through the water channel heat exchanger 141, and the domestic water is heated.
Because the requirement on the water temperature of the domestic hot water is not high and is about within 38-45 ℃, the heat exchange between the water and the water by utilizing the water path heat exchanger 141 can meet the temperature requirement. Therefore, the mode of realizing secondary heat exchange by additionally arranging the water path heat exchanger 141 avoids the direct heat exchange of the domestic water pipeline 151 with the refrigerant pipeline 111 through the fluorine water heat exchanger 121, protects the fluorine water heat exchanger 121 from being corroded by the running water, and further ensures the normal work of the air conditioning system 110.
In this embodiment, the floor heating pipeline 131 includes a heat exchange pipeline 132 and a floor heating coil 133, the heat exchange pipeline 132 exchanges heat with the refrigerant pipeline 111 through the fluorine water heat exchanger 121, and the floor heating coil 133 and the water channel heat exchanger 141 are arranged at two ends of the heat exchange pipeline 132 in parallel. The floor heating coil 133 and the water path heat exchanger 141 are in an independent parallel connection relationship, and multiple working modes can be switched between floor heating heat supply and domestic hot water supply by cooperatively controlling the opening and closing of a connecting pipeline of the floor heating coil 133 and the water path heat exchanger 141.
It should be noted that the triple co-generation system 100 provided in this embodiment further includes a controller (not shown in the figure), a hot water waterway electric valve 1411 is disposed on the water inlet end pipeline of the waterway heat exchanger 141, the hot water waterway electric valve 1411 is electrically connected to the controller, and the opening of the hot water waterway electric valve 1411 is adjusted under the control of the controller. The water flowing in from the water inlet end of the water path heat exchanger 141 is the hot water output from the heat exchange pipeline 132 of the floor heating pipeline 131, that is, a part of the hot water after heat exchange between the fluorine water heat exchanger 121 and the refrigerant pipeline 111 in the heat exchange pipeline 132 can flow into the water path heat exchanger 141 as a heating source of the domestic water pipeline 151, and the other part can flow into the floor heating coil 133 as the heating water to perform floor heating heat supply.
It can be understood that a heating water circuit electric valve 1331 is arranged on the water inlet end pipeline of the floor heating coil 133, and the heating water circuit electric valve 1331 is electrically connected with the controller and is used for adjusting the opening under the control of the controller.
In practical applications, the controller can adjust the flow rate of the hot water entering the water channel heat exchanger 141 and the flow rate of the hot water entering the floor heating coil 133 by cooperatively controlling the opening degrees of the hot water channel electric valve 1411 and the heating water channel electric valve 1331, so as to adjust the heating temperature of the domestic water channel 151.
When floor heating is needed to be carried out independently, the controller controls the hot water path electric valve 1411 to be closed completely, controls the heating water path electric valve 1331 to be adjusted to a certain opening degree, hot water output by the heat exchange pipeline 132 flows into the floor heating coil 133 completely, and adjusts the flow rate of hot water in the floor heating coil 133 by adjusting the opening degree of the heating water path electric valve 1331, so that the adjustment of the temperature of the floor heating is realized.
When the hot water is required to be supplied separately, the controller controls the heating water path electric valve 1331 to be completely closed, controls the hot water path electric valve 1411 to be adjusted to a certain opening degree, allows all the hot water output by the heat exchange pipeline 132 to flow into the water path heat exchanger 141 to heat the domestic water path 151, and adjusts the temperature of the domestic hot water by adjusting the opening degree of the hot water path electric valve 1411.
When the floor heating and the domestic water are required to be supplied simultaneously, the controller controls the hot water path electric valve 1411 and the heating water path electric valve 1331 to be adjusted to a certain opening degree, and the controller can realize the temperature adjustment of the domestic water and the heating water by cooperatively controlling the opening degrees of the hot water path electric valve 1411 and the heating water path electric valve 1331.
For example, when the controller controls the opening of the hot water waterway electric valve 1411 to increase and controls the opening of the heating waterway electric valve 1331 to decrease, the temperature of the domestic hot water rises and the temperature of the heating water decreases; when the controller controls the opening of the heating water path electric valve 1331 to increase and the opening of the hot water path electric valve 1411 to decrease, the temperature of the heating water rises and the temperature of the domestic hot water decreases.
In addition, in this embodiment, a heating device 1321 is disposed at the water outlet end of the heat exchange pipeline 132, and the heating device 1321 is electrically connected to the controller, and is configured to heat the water in the heat exchange pipeline 132 under the control of the controller. Considering that the heat exchange capacity of the fluorine water heat exchanger 121 is limited, which may cause the temperature of the heating water or the domestic water to not reach the standard in time, in this case, the controller controls the heating device 1321 to be turned on to actively heat the water outlet end of the heat exchange pipeline 132, so as to rapidly increase the temperature of the hot water entering the water channel heat exchanger 141 and the temperature of the hot water entering the floor heating coil 133.
The water outlet end of the domestic water pipeline 151 is provided with a temperature flow sensor 1511, the temperature flow sensor 1511 is electrically connected with the controller, and the temperature flow sensor 1511 is used for monitoring the water temperature and the flow of the water outlet end of the domestic water pipeline 151.
In practical application, the temperature and flow sensor 1511 feeds back the monitored temperature and flow data to the controller, the controller determines whether the temperature of the domestic water reaches the standard according to the received data, if the temperature is too low, the controller controls the opening degree of the hot water waterway electric valve 1411 to be increased, and if the temperature of the domestic hot water still does not reach the standard when the opening degree of the hot water waterway electric valve 1411 is adjusted to be maximum, the controller controls the heating device 1321 to be opened, and the water outlet end of the heat exchange pipeline 132 is actively heated.
Because domestic water pipeline 151 is the running water input, when the access running water, domestic water pipeline 151's pressure is greater than ground heating pipe 131 operating pressure 1.5bar usually, consequently, monitors the pressure of water route heat exchanger 141 connecting line and can in time judge whether water route heat exchanger 141 takes place to reveal in practical application to in time maintain. Therefore, in this embodiment, a pressure sensor 1413 is further disposed on the water outlet end pipeline of the water circuit heat exchanger 141, and the pressure sensor 1413 is electrically connected to the controller for monitoring the pipeline pressure at the water outlet end of the water circuit heat exchanger 141.
In practical application, the triple co-generation system 100 may further be configured with an alarm device, the alarm device is electrically connected to the controller, and when the controller determines that the waterway heat exchanger 141 leaks according to the pressure data fed back by the pressure sensor 1413, the controller sends an alarm signal to the alarm device, so that the alarm device gives an alarm to remind a user of maintenance and repair.
In practical application, when a user needs to independently heat the floor heating, the controller controls the hot water waterway electric valve 1411 to be closed and controls the heating waterway electric valve 1331 to be opened; when a user needs to use domestic hot water alone, under the condition, when the temperature and flow sensor 1511 monitors that water flows at the water outlet end of the domestic water pipeline 151, the controller controls the heating water channel electric valve 1331 to be temporarily closed, and due to the fact that the thermal inertia of water is large, the influence of no heat input on the overall temperature of a room in a short period of time is small, and the user perception is not obvious. Subsequently, the controller controls the hot water waterway electric valve 1411 to be opened. After the waterway electric valve is opened, the controller monitors whether the outlet water temperature of the domestic water pipeline 151 reaches the standard through the temperature flow sensor 1511, so as to control and adjust the opening of the hot water waterway electric valve 1411.
In this example, when it is detected that the outlet water temperature of the domestic water pipeline 151 exceeds 45 ℃, the controller controls the hot water waterway electric valve 1411 to adjust the opening degree until the outlet water temperature of the domestic water pipeline 151 is between 38 ℃ and 45 ℃, or the hot water waterway electric valve 1411 is already at the minimum opening degree value.
When the outlet water temperature of the domestic water pipeline 151 is lower than 38 ℃, the controller controls the heating water channel electric valve 1331 to be closed, if the heating water channel electric valve 1331 is in a closed state, the controller controls the opening of the hot water channel electric valve 1411 to be increased, and if the hot water channel electric valve 1411 is detected to be adjusted to be in a maximum opening, the controller controls the heating device 1321 to be opened, and the outlet water end of the heat exchange pipeline 132 is actively heated.
In addition, in this embodiment, the water outlet end of the heat exchange pipeline 132 is further provided with a target flow switch 1323, a safety valve 1325 and an exhaust valve 1327, the target flow switch 1323 is used for detecting water blockage, the safety valve 1325 can discharge water when the pressure of the pipeline is too high, it is ensured that the pressure in the pipeline does not exceed a limit value, and the exhaust valve 1327 plays a role in exhausting system air.
And, the return water end of the heat exchange pipeline 132 is provided with a water pump 1328 and an expansion tank 1329, the water pump 1328 is electrically connected with the controller for providing power for the water flow in the floor heating pipeline 131, and the expansion tank 1329 plays a role in stabilizing the system pressure.
In the triple co-generation system 100 provided in this embodiment, by additionally providing the water path heat exchanger 141, after the heating water is subjected to the first heat exchange with the fluorine water heat exchanger 121, the heating water is subjected to the second heat exchange with the domestic water in the domestic water pipeline 151 through the water path heat exchanger 141, so as to heat the domestic water. Avoided domestic water pipeline 151 to carry out the heat transfer through fluorine water heat exchanger 121 and refrigerant pipeline 111 to avoided the running water in domestic water pipeline 151 to get into fluorine water heat exchanger 121, prevented that fluorine water heat exchanger 121 from being corroded by the running water, prolonged fluorine water heat exchanger 121's life, and then promoted the whole security of the trigeminy confession system 100 that this embodiment provided.
