In an alternative embodiment, the conducting valves include an input conducting valve 231 and an output conducting valve 232, the input conducting valve 231 is serially connected to the pipeline of the first energy input end 201, and the output conducting valve 232 is serially connected to the pipeline of the first energy output end 202. The purpose of the on-off valve is to control the opening or closing of the first energy input 201 and the first energy output 202. In a specific embodiment, an input end conduction valve 231 is disposed on the liquid inlet pipe and the liquid outlet pipe of each first energy input end 201 (each heat exchange device), and an output end conduction valve 232 is disposed on the liquid inlet pipe and the liquid outlet pipe of each first energy output end 202 (each heat exchange device). The opening and closing control, the flow control and the energy transfer regulation of the communication pipelines of the first energy input end 201 and the first energy output end 202 of the first intermediate heat exchanger 20 are respectively realized by controlling the respective conduction valves, and the heat exchange between the first heat regulation device 40 and the second heat regulation device 50 can be controlled according to actual conditions.
A first energy input terminal 201 for inputting the cooling energy (or the heating energy) of the first evaporator 41 (or the second condenser 52) side. The specific structure adopted is various, for example, a fluid medium is used as a carrier, the first energy input end 201 is communicated with the heat exchange device on the side of the first evaporator 41 (or the second condenser 52) through a pipeline by using a heat exchange device, the fluid medium absorbs cold (or heat) on the side of the first evaporator 41 (or the second condenser 52), the fluid medium flows to the first energy input end 201, and the first energy input end 201 exchanges heat with the medium fluid of the first energy output end 202, so that the energy is converted to the first energy output end 202.
In an alternative embodiment, the first energy input end 201 is embodied by a heat exchange device, such as a plate heat exchanger, an evaporator, or a heat exchange coil. The first energy output end 202 is specifically a heat exchange device, such as a plate heat exchanger, a condenser, or a heat exchange coil.
In the relay heat exchanger according to the embodiment of the present invention, the number of the first energy input ends 201 and the first energy output ends 202, and the arrangement of the external connection pipeline groups of the first energy input ends 201 and the first energy output ends 202 may be determined according to the number of the evaporators and the condensers on the connection side, and other factors.
In an alternative embodiment, the number of the first energy input ends 201 of the first intermediate heat exchanger 20 according to the embodiment of the present invention is one or more, and the piping of each first energy input end 201 is independently provided. For example, the first energy input 201 includes one (as shown in fig. 4, 5 and 9) or more (see the first energy output 202 of the relay heat exchanger 20 in fig. 7) third heat exchange devices, each of which has an inlet pipe 211 and an outlet pipe 212 (i.e., a group of communicating pipes 21), and is communicated with the first evaporator 41 through two pipes, specifically, with the first cold heat exchange device on the side of the first evaporator 41, or is communicated with the second condenser 52 through two pipes, specifically, with the second heat exchange device on the side of the second condenser 52.

For another example, as shown in fig. 6 and 8, the first energy input end 201 is a third heat exchange device, and the liquid inlet end of the third heat exchange device is communicated with a plurality of liquid inlet pipes 211, and the liquid outlet end of the third heat exchange device is communicated with a plurality of liquid outlet pipes 212. One liquid inlet pipe 211 and one liquid outlet pipe 222 are formed as one communication pipe group 21 into a plurality of independent communication pipe groups, and are respectively communicated with each first evaporator 41 (or each second condenser 52) through the plurality of independent communication pipe groups.
In another alternative embodiment, the number of the first energy input ends 201 is multiple, and the pipelines of the multiple first energy input ends 201 are communicated with each other. There are many ways of communicating with each other, as long as it is achieved that a plurality of first energy input ends can all communicate with the first evaporator 41 of the first heat regulating device 40 or the first condenser 42 of the first heat regulating device 40. For example, as shown in fig. 7, the plurality of first energy input ends 201 are communicated with the liquid outlet transit pipe 222 through the liquid inlet transit pipe 221, the liquid inlet pipe 211 of each first energy input end 201 is communicated with the liquid inlet transit pipe 221, and the liquid outlet pipe 212 of each first energy input end 201 is communicated with the liquid outlet transit pipe 222. And then the liquid inlet transit pipeline 221 and the liquid outlet transit pipeline 222 are used as a communicating pipeline group and are communicated with the first evaporator 41 (or each second condenser 52) through two pipelines.
Similarly, when there are one or more first energy output ends 202, the pipeline of each first energy output end 202 is independently arranged in the same manner as the first energy input end 201. When there are a plurality of first energy output ends 202, the pipelines of the plurality of first energy output ends 202 are connected to each other in the same way as the first energy input end 201. And will not be described in detail herein.

That is, the first energy input 201 and the first energy output 202 are independently arranged in a pipeline. One path is converted into multiple paths.
As shown in fig. 5, in the first intermediate heat exchanger ii, there is one first energy input end 201, and there is one communicating pipe set; the number of the first energy output ends 202 is one, and one first energy output end 202 has a plurality of independently arranged communicating pipe groups. That is, the first energy input 201 and the first energy output 202 are independently arranged in a pipeline. One path is converted into multiple paths.
As shown in fig. 6, in the first relay heat exchanger iii, there is one first energy input end 201, and one first energy input end 201 has a plurality of independently arranged communicating pipe sets; the first energy output 202 is one, having one communicating tube bank. That is, the first energy input 201 and the first energy output 202 are independently arranged in a pipeline. And (4) converting the multiple paths into one path.
As shown in fig. 7, in the first intermediate heat exchanger v, the first energy input end 201 is plural, and the plural first energy input ends 201 are communicated with each other by a group of communicating tube sets to be communicated with the first evaporator 41 of the first heat regulating device 40 or the first condenser 42 of the first heat regulating device 40; the number of the first energy output ends 202 is plural, and the communicating pipe groups of the plural first energy output ends 202 are independently arranged. That is, the pipelines of the plurality of first energy input terminals 201 communicate with each other, and the pipelines of the plurality of first energy output terminals 202 are independently provided. One path is converted into multiple paths.
As shown in fig. 8, in the first intermediate heat exchanger iv, there is one first energy input end 201, and one first energy input end 201 has a plurality of independently arranged communicating pipe sets; the number of the first energy output ends 202 is one, and one first energy output end 202 has a plurality of independently arranged communicating pipe groups. That is, the first energy input 201 and the first energy output 202 are independently arranged in a pipeline. And (4) multiplexing the multiple paths.
As shown in fig. 9, in the first relay heat exchanger vi, there is one first energy input end 201, and there is one communicating pipe group; the first energy output 202 is one, having one communicating tube bank. That is, the first energy input 201 and the first energy output 202 are independently arranged in a pipeline. One path is changed into another path.
Of course, the structures of the first intermediate heat exchanger 20 according to the embodiment of the present invention are not limited to the above six, and the structures of the first energy input end 201 and the first energy output end 202 may be interchanged and may be combined arbitrarily. In practical application, the structure of the adaptive intermediate heat exchanger is selected. In addition, when the communication pipes of the first energy input end 201 (or the first energy output end 202) of the first intermediate heat exchanger 20 are formed into a plurality of sets, the number is not limited, and may be determined according to the number of the first evaporators 41 (or each second condenser 52) to be connected.
In the first relay heat exchanger 20 according to the embodiment of the present invention, the heat exchange device of the first energy input end 201 and the heat exchange device of the first energy output end 202 may be separately arranged, for example, when a plate heat exchanger is adopted, the two heat exchange devices are oppositely arranged (may be contacted or not contacted), so as to ensure that the heat exchange area is maximized; when the heat exchange coil is adopted, the coil parts of the heat exchange coil and the heat exchange coil are arranged in a staggered mode (can be contacted or not contacted), and effective heat exchange is guaranteed. Alternatively, the heat exchange device of the first energy input end 201 and the heat exchange device of the first energy output end 202 are designed as a whole. The arrangement is not limited, as long as the heat exchange device of the first energy input end 201 and the heat exchange device of the first energy output end 202 can perform heat transfer. As shown in fig. 4 to 9, the first energy input end 201 and the first energy output end 202 are both configured by contactless heat exchanging devices disposed oppositely, although the first intermediate heat exchanger according to the embodiment of the present invention is not limited to the configuration shown in the drawings.
The first energy input end 201 and the first energy output end 202 of the first intermediate heat exchanger 20 according to the embodiment of the present invention have the same structure when the heat exchange manner is the same, and the two energy input ends and the first energy output end can be used interchangeably, which is only defined for convenience of distinction.
As shown in fig. 10 and 11, the second intermediate heat exchanger 30 includes:
a first energy input end I301, which is used for communicating with the first evaporator 41 of one or more first heat regulating devices 40 or the first condenser 42 of one or more first heat regulating devices 40;
a first energy output I302 for communication to one or more mixing units 10; and the combination of (a) and (b),
the one-way heat conduction device 31, the first energy input end I301 and the first energy output end I302 are arranged at two ends of the one-way heat conduction device 31.
In the second intermediate heat exchanger 30 according to the embodiment of the present invention, by adding the unidirectional heat conducting device 31, when the first evaporator 41 exchanges cooling capacity with the second evaporator 51, more accurate cooling capacity transfer can be provided to the second evaporator 51 according to the target parameter (e.g., the target temperature) of the second evaporator 51. When supplying cooling energy to the second evaporator 51, the temperature of each fluid medium entering the mixing unit 41 can be precisely adjusted according to the temperature difference value between the target temperature and the actual temperature of the second evaporator 51, and the fluid medium with the set temperature can be precisely obtained by combining the flow control. In addition, the present invention is also applicable to a case where energy transmission in a predetermined direction is not possible between the first evaporator 41 and the second evaporator 51 (or between the second condenser 52 and the first condenser 42). In general, heat transfer is performed only from the higher temperature end to the lower temperature end, for example, if the heat exchange direction between the second condenser 52 and the first condenser 42 is set such that the second condenser 52 exchanges heat with the first condenser 42, and if the medium temperature itself on the second condenser 52 side is lower than the medium temperature itself on the first condenser 42 side, the heat exchange cannot be performed in the set direction, but rather, heat loss on the first condenser 42 side occurs, and the opposite effect is achieved.

By controlling the direction of the power supply current, the first end and the second end of the semiconductor refrigeration chip can be switched between two modes of heat generation and cold generation. For example, at a forward current, the first end is a cold end and the second end is a hot end; after the current direction is switched, the first end is switched to be the hot end, and the second end is switched to be the cold end. The second intermediate heat exchanger 30 includes two heat-absorbing chambers 303 and two heat-releasing chambers 304 which are arranged in a heat-insulating manner; the first end heat exchanger is arranged opposite to the first energy input end I301 of the second intermediate heat exchanger 30 and is arranged in the heat absorption chamber 303; the second end heat exchanger is disposed opposite to the first energy output end i 302 of the second intermediate heat exchanger 30 and is disposed in the heat release chamber 304.

In an alternative embodiment, the energy system ii comprises two first thermal conditioners 40 (air conditioners in heating mode) and two second thermal conditioners 50 (refrigerators). As shown in fig. 14, the first evaporators 41 of the two first heat regulating devices 40 are in heat exchange communication with the second evaporators 51 of the two second heat regulating devices 50 (refrigerators) through the medium distribution mixing device iii; the two first evaporators 41 supply cooling energy to the two second evaporators 51.

In an alternative embodiment, the energy system further comprises a control device for controlling the opening degree of the flow control valve 11 of the first medium distribution and mixing device (medium distribution and mixing device i or medium distribution and mixing device ii) according to the temperatures of the first evaporators 41 of the plurality of first heat regulating devices 40 and the temperatures of the second evaporators 51 of the plurality of second heat regulating devices 50; and controlling the opening degree of the flow control valve 11 of the second medium distribution mixing device (medium distribution mixing device i or medium distribution mixing device ii) according to the temperatures of the first condensers 42 of the plurality of first heat quantity adjusting devices 40 and the temperatures of the second condensers 52 of the plurality of second heat quantity adjusting devices 50.
In the present embodiment, a control process (control method) of the control apparatus will be described by taking, as an example, the plurality of first evaporators 41 of two first heat quantity adjusting devices 40 (air conditioners in heating mode) and one second evaporator 51 of one second heat quantity adjusting device 50 (refrigerator). The flow control valve 11 is provided on the line of the first energy output end of the relay heat exchanger 20 (or 30), and can control the flow rate of each communicating line group. The required cooling capacity (e.g., the medium temperature) can be obtained according to the target temperature and the actual temperature of the second evaporator 51, and the cooling capacity is determined, i.e., the set temperature of the second output end of the mixing unit 10 corresponding to the second evaporator 51 can be determined. In general, the cold medium temperatures of the heat exchangers of the two first evaporators 41 are generally different, i.e. different cold medium temperatures of the first evaporators 41 can provide different cold. The set temperature is thus obtained by proportionally mixing the cold medium on the side of the two first evaporators 41, depending on the set temperature. The cold energy mediums at the two first evaporators 41 are mixed in proportion by controlling the opening degree of the flow control valve on the corresponding communication pipeline on the first energy output end of the transit heat exchanger. Similarly, when the plurality of first evaporators 41 are required to supply cooling capacity to the plurality of second evaporators 51, the set temperatures of the second output ends of the mixing units 10 corresponding to the second evaporators 51 are respectively determined, and the opening degree of the flow control valve on the corresponding communication pipeline on the first energy output end of the transfer heat exchanger correspondingly connected to each mixing unit 10 is determined according to the cooling capacity medium temperature of the heat exchange device on each first evaporator 41 side. For more details, reference may be made to the following section of the control method of the energy system.

Specifically, the control process will be described taking the communication between the first condenser 42 and the second condenser 52 as an example. By detecting the second medium temperature on the second condenser 52 side (the heat medium temperature of the heat exchange device described below) and the first medium temperature on the first condenser 42 side (the set temperature described below), the relationship between the first medium temperature and the second medium temperature is determined, and whether or not heat exchange is possible between the first condenser 42 and the second condenser 52 in the set direction is determined. For example, the heat exchange direction is set such that heat is supplied from the second condenser 52 to the first condenser 42, and this is achieved on the premise that the second medium temperature on the second condenser 52 side is higher than the first medium temperature on the first condenser 42 side. Therefore, when the second medium temperature is lower than the first medium temperature, the heat exchange between the first condenser 42 and the second condenser 52 cannot be performed in the set direction, and at this time, the switching device is controlled so that the communication path for switching the heat exchange between the first condenser 42 and the second condenser 52 is communicated through the bypass relay heat exchanger (second relay heat exchanger 30) in the medium distribution mixing device iii. By analogy, the control principle of the cold quantity exchange between the first evaporator 41 and the second evaporator 51 is the same and will not be described again here. For more details, reference may be made to the following section of the control method of the energy system.
