The second end of the cold coil electromagnetic valve 14 is connected to the refrigerant generator 19.
Optionally, the cold source system includes the following three operation modes:
when the cold source system is in the first operation mode, the spray water solenoid valve 17 and the cold coil solenoid valve 14 are both in an open state, and the vent valve 12 is in a closed state.
When the cold source system is in the second operation mode, the shower water solenoid valve 17 and the vent valve 12 are both in an open state, and the cold coil solenoid valve 14 is in a closed state.
When the cold source system is in the third operation mode, the shower water solenoid valve 17 and the cold coil solenoid valve 14 are both in a closed state, and the vent valve 12 is in an open state.
Optionally, the cooling mode of the cooling medium generator 19 is natural energy cooling or waste heat cooling.
The refrigeration mode of the natural energy refrigeration comprises at least one of the following modes: solar refrigeration, wind energy refrigeration and water energy refrigeration.
In practical application, when the cold source system is in a first operation mode, the air heat exchanger receives indoor air through the indoor air inlet and receives outdoor air through the outdoor air inlet, the indoor air and the outdoor air exchange heat in the air heat exchanger, meanwhile, spray water sprays water to the air heat exchanger, and at the moment, the outdoor air is used as a natural cold source to continuously take away heat of the indoor air in a spray water spraying process; the cold air after heat exchange passes through the cold coil pipe, and after the cold coil pipe takes away the residual heat in the cold air, the cold air passes through the internal circulation fan and the indoor air outlet in sequence and is input into the room; the hot air after heat exchange passes through the external circulation fan and the outdoor air outlet in sequence and is discharged outdoors. The first operation mode is equivalent to a normal operation mode in which the energy consumption of the heat sink system is highest.
When the cold source system is in a second operation mode, the air heat exchanger receives indoor air through the indoor air inlet and receives outdoor air through the outdoor air inlet, the indoor air and the outdoor air exchange heat in the air heat exchanger, meanwhile, spray water sprays to the air heat exchanger, and at the moment, the outdoor air is used as a natural cold source to continuously take away heat of the indoor air in the spray water spraying process; the cold air after heat exchange sequentially passes through the ventilation valve, the internal circulation fan and the indoor air outlet and is input into the room, and the hot air after heat exchange sequentially passes through the external circulation fan and the outdoor air outlet and is discharged out of the room. The first operation mode is equivalent to an energy-saving operation mode, and the energy consumption of the cold source system in the first operation mode is higher than that in the third operation mode and lower than that in the third operation mode, namely, the energy consumption can still be kept low.
When the cold source system is in a third operation mode, the air heat exchanger receives indoor air through the indoor air inlet and receives outdoor air through the outdoor air inlet, the air heat exchanger performs air heat exchange on the indoor air and the outdoor air, then cold air after heat exchange sequentially passes through the ventilation valve, the internal circulation fan and the indoor air outlet to be input into a room, and hot air after heat exchange sequentially passes through the external circulation fan and the outdoor air outlet to be discharged out of the room. The third mode of operation corresponds to a low energy mode of operation in which the energy consumption of the heat sink system is minimized.
In the embodiment of the application, the cold source system is prevented from being always in a high-energy-consumption working state by switching different operation modes, so that the energy consumption of the cold source system is effectively reduced; in addition, the refrigerant generator provides a cold source for the cold coil pipe by utilizing a natural energy refrigeration or waste heat refrigeration mode, thereby greatly saving energy, saving the running cost of a cold source system and being beneficial to environmental protection.
Fig. 2 is a schematic flow chart illustrating an implementation process of a method for controlling a cold source system according to an embodiment of the present application, as shown in the figure, the method may include the following steps:

According to the cold source system, the cold source system is controlled to be switched to the corresponding running mode according to the indoor temperature and the outdoor temperature, the working state that the cold source system is always in high energy consumption is avoided, the energy consumption of the cold source system in the running process is effectively reduced, and the running cost of the cold source system is saved.
Fig. 3 is a schematic flow chart illustrating an implementation process of a control method of a cold source system according to another embodiment of the present application, and as shown in the drawing, step S203 may include the following steps:
and S301, subtracting the indoor temperature from the outdoor temperature to obtain a temperature difference.

Step S303, if the temperature difference is smaller than a first preset value and larger than a second preset value, adjusting the operation mode of the cold source system to a second operation mode.
Step S304, if the temperature difference is less than or equal to a second preset value, adjusting the operation mode of the cold source system to a third operation mode.
The first preset value and the second preset value can be manually preset, and the first preset value and the second preset value are used for distinguishing the range of the temperature difference, so the scheme can also be used for directly setting the range of the temperature difference, and if the temperature difference is within the first preset range, the operation mode of the cold source system is adjusted to be the first operation mode; if the temperature difference is within a second preset range, adjusting the operation mode of the cold source system to be a second operation mode; and if the temperature difference is within a third preset range, adjusting the operation mode of the cold source system to a third operation mode.
In practical application, when the outdoor temperature is higher in summer, the indoor and outdoor temperature difference is larger than a first preset value, the operation mode of the cold source system is adjusted to be the first operation mode, the cold source system is required to efficiently cool the indoor air, and therefore the energy consumption of the cold source system is highest; when the outdoor temperature is close to the indoor temperature in the transition season, the indoor and outdoor temperature difference is smaller than the first preset value and larger than the second preset value, the operation mode of the cold source system is adjusted to be the second operation mode, the cold source system can be cooled by only using spray water, and the energy consumption of the cold source system is low; when the outdoor temperature is lower in winter, the indoor and outdoor temperature difference is smaller than the second preset value, the operation mode of the cold source system is adjusted to be the third operation mode, the outdoor air can be used as a natural cold source to cool the indoor air, and the energy consumption of the cold source system is the lowest.
In an embodiment of the present application, the adjusting the operation mode of the heat sink system to the first operation mode includes:
opening a spray water electromagnetic valve and a cold coil electromagnetic valve of the cold source system;
and closing a ventilation valve of the cold source system.
In an embodiment of the present application, the adjusting the operation mode of the heat sink system to the second operation mode includes:
opening a spray water electromagnetic valve and a ventilation valve of the cold source system;
and closing the cold coil electromagnetic valve of the cold source system.
In an embodiment of the present application, the adjusting the operation mode of the heat sink system to the third operation mode includes:
closing a spray water electromagnetic valve and a cold coil electromagnetic valve of the cold source system;
and opening a ventilation valve of the cold source system.
According to the cold source system and the control method, the operation mode of the cold source system is adjusted at any time through the temperature difference of indoor and outdoor temperatures, the cold source system is prevented from being always in a high energy consumption state, and therefore energy consumption of the cold source system in the operation process is effectively reduced, and the operation cost of the cold source system is saved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
Fig. 4 is a schematic flow chart illustrating a control method of a cold source system according to another embodiment of the present application, as shown in the figure, step S203 may further include the following steps:
and S401, subtracting the indoor temperature from the outdoor temperature to obtain a temperature difference.
Step S402, acquiring the outdoor humidity.
In step S403, if the temperature difference is greater than or equal to a first preset value and the outdoor humidity is greater than a third preset value, the operation mode of the cold source system is adjusted to the first operation mode.
Step S404, if the temperature difference is smaller than a first preset value, larger than a second preset value, and the outdoor humidity is smaller than a third preset value, adjusting the operation mode of the cold source system to a second operation mode.
Step S405, if the temperature difference is less than or equal to a second preset value, adjusting the operation mode of the cold source system to a third operation mode.
In the embodiment of the present application, steps S401 and S405 are similar to steps S301 and S304, and specific reference may be made to the specific description in steps S301 and S304.
In practical applications, not only temperature but also humidity may be taken into account. When the outdoor temperature is high and the outdoor humidity is high, the cold source system and the spray water electromagnetic valve need to be opened simultaneously, which is often seen in summer. When the indoor temperature and the outdoor temperature are close to or slightly lower than the outdoor temperature and the outdoor humidity is low, the electromagnetic valve and the ventilation valve of the spray water are required to be opened, which is often seen in transition seasons. When the spray water electromagnetic valve is opened, spray water is sprayed into the air, and the air is cooled by evaporation of moisture.
