Example 1
Referring to fig. 1, a first aspect of the present invention discloses a temperature regulation system, which includes a cold energy regulation end, an air conditioning end, a radiation refrigeration device, a room temperature sensor (not shown in the figure), and a controller (not shown in the figure).
The air conditioning end comprises an evaporator 110, a compressor 120, a condenser 130 and a throttle valve 140, which are sequentially connected by refrigerant pipes to form a circulation loop.

The radiant refrigeration unit 310 exchanges heat with the heat exchanger 220. In this way, a combined system with the cold energy adjusting end, the air conditioning end and the radiation refrigerating device 310 as main constituent units is formed for realizing refrigeration or heating.

In a preferred embodiment, the power of the peltier cooler 210 is supplied by solar photovoltaic panels, which are located on the roof or outer wall of the building to convert solar energy into electrical energy for use by the peltier cooler 210 to further save energy consumption.
In a preferred embodiment, the surface of the radiant refrigeration unit 310 is provided with a non-uniform bellows structure to increase the area and efficiency of the external radiation. The conventional coating can only realize high radiation and high reflection, and the invention configures the surface coating of the radiation refrigeration device 310 as a thermal change material, an electric change material or a mechanical strain material so as to change the surface coating into low radiation and low reflection properties when heating is required.
The controller obtains a set temperature, an indoor average temperature, an outlet side temperature of the indoor coil 230, an inlet side temperature of the indoor coil 230, etc., and controls the start and stop of the air conditioning end and/or peltier cooler 210 and/or the radiant refrigeration device 310. The controller obtains a set flow rate of the indoor coil 230, an actual flow rate of the indoor coil 230, a set wind speed of the indoor coil 230, an actual wind speed of the indoor coil 230, and the like, and adjusts the working parameters of the cooling energy adjusting end.
The operation principle of the temperature adjustment system and its preferred embodiments will be further described in example 2, which is not repeated here.
Example 2
In a second aspect the invention discloses a temperature regulation method for realizing the temperature regulation of a building by means of a temperature regulation system as disclosed in example 1.
Referring to fig. 3, a temperature adjustment method includes:
configuring the temperature regulation system as described in embodiment 1;
configuring the temperature regulation mode of the controller into a refrigeration mode and a heating mode, and acquiring the current operation mode of the temperature regulation system;
Acquiring a set temperature T, an indoor average temperature T 1, an inlet side temperature T 21 of the indoor coil 230, an outlet side temperature T 22 of the indoor coil 230, a set flow velocity V and a cold carrying tube flow velocity V 2 of the indoor coil 230; setting the fan rotating speed S of the indoor coil 230 and the actual fan rotating speed S 2;
The air conditioner, the peltier cooler 210 and the radiation refrigeration device 310 are controlled to be turned on or off according to the first temperature difference T 31, the second temperature difference T 32, the inlet side flow velocity V 2 of the indoor coil 230 and the actual fan speed S 2.
Specifically, please refer to fig. 4, in the cooling mode:
Acquiring a set temperature T and an indoor average temperature T 1, and acquiring a first temperature difference value T 31,T31=T1 -T; acquiring a set temperature T and an outlet side temperature T 22 of the indoor coil 230; obtaining a second temperature difference T 32,T32=T-T22;
When T 31 is greater than a first set threshold value, T 41, executing a first operation state, and simultaneously starting an air conditioner end, the Peltier refrigerator 210 and the radiation refrigeration device 310 in the first operation state, and keeping operation for T time;
When T 31 is greater than the second set threshold, T 42, executing a second operation state, in which the refrigeration efficiency in the air-conditioner low-power operation state is not higher than that of the peltier cooler 210 in the low-power operation state, and at this time, the air-conditioner is kept closed, and the peltier cooler 210 and the radiation refrigeration device 310 are kept open, so as to save energy consumption and keep the operation time T;
When T 31 is greater than a third set threshold value, T 43, executing a third running state, keeping the air-conditioning end and the Peltier refrigerator 210 closed, keeping the radiation refrigerating device 310 open, and keeping the running for a time T;
The first set threshold T 41 is greater than the second set threshold T 42 and greater than the third set threshold T 43, so that whether each device participates in refrigeration can be flexibly adjusted through the difference between the set temperature T and the indoor average temperature T1, and the energy consumption required for temperature adjustment is reduced as much as possible on the premise of ensuring that the temperature adjustment time is acceptable. In one practical example, the first set threshold T 41 may be set to 8, the second set threshold T 42 to 6, and the third set threshold T 43 to 4.
In order to further reduce the temperature adjustment time, the present invention further provides a flow rate sensor at the inlet side of the indoor coil 230 to monitor the flow rate of the refrigerant in the indoor coil 230, and a rotation rate sensor at the outlet side of the indoor coil 230 to monitor the wind speed at the outlet side of the indoor coil 230, so as to adjust the execution state of the system according to the set flow rate V of the indoor coil 230, the actual flow rate V 2 of the indoor coil 230, the set fan rotation speed S of the indoor coil 230, and the actual fan rotation speed S 2 of the indoor coil 230.
When the system is in the first operation state, the actual flow velocity V2 of the indoor coil 230 keeps the maximum flow velocity operation state, the actual fan speed S 2 keeps the maximum rotation speed operation state, and the operation time is gradually reduced to the set flow velocity V, and the fan speed S of the indoor coil 230 is set;
When the system is in the second or third operating state, the actual flow rate V2 of the indoor coil 230 remains at the set flow rate V, the actual fan speed S 2 remains at the maximum speed operating state, and the fan speed S of the indoor coil 230 is gradually reduced as the operating time is followed.
When the system is in the first operating state, the second temperature difference T 32 is monitored, and when T 32 is greater than the fourth set threshold T 44, the temperature of the indoor coil 230 is too low, and the refrigerating capacity is excessive. In the first operation state, the refrigeration efficiency of the peltier cooler 210 in the high-power operation state is not as good as that of the air-conditioning end in the high-power operation state, at this time, the peltier cooler 210 is turned off preferentially, and the original refrigeration function of the peltier cooler 210 is replaced by the air-conditioning end, so as to save energy consumption.
When the system needs to start a heating mode, on one hand, the temperature difference is larger than that when the system needs to start a cooling mode (the proper temperature of a human body is generally 26 ℃, the human body usually has obvious uncomfortable feeling at 30 ℃, the system usually starts cooling, and for the heating mode, the system is usually started when the temperature is smaller than 10 ℃, and the temperature difference is usually obviously larger than that when the cooling mode is started); on the other hand, unlike the cold air in the cooling mode, the hot air floats up due to the small density, so that the user perceives the change of the room temperature in the heating mode to be weaker than the room temperature in the cooling mode; therefore, in the heating mode, the air conditioner, the peltier cooler 210 and the radiation cooling device 310 are turned on to reach the temperature suitable for the user's perception as soon as possible.
In order to save energy in the heating mode and prevent the heating mode from being turned on by mistake, please refer to fig. 4, when the system is in the heating mode: acquiring an inlet side temperature T 21 of the indoor coil 230 and an outlet side temperature T 22 of the indoor coil 230; obtaining a third temperature difference T 33,T33=T22-T21; setting a fifth set threshold T 55, when the outlet temperature is greater than the inlet temperature in T 33>T55, which indicates that the heating amount is excessive or heating may not be needed, at this time, closing the air-conditioning end (because the air-conditioning end saves energy when the heating demand is large, the air-conditioning end is not as economical as the peltier cooler 210 when the heating demand is small, so the air-conditioning end is preferentially closed), and keeping the peltier cooler 210 and the radiation refrigeration device 310 on for heating; when T 33 is still greater than T 55 after the air conditioner is turned off for a preset period of time (e.g., 1-3 minutes), the Peltier refrigerator 210 is turned off; after the peltier cooler 210 is turned off for a preset period (e.g., 1-3 minutes), the radiant refrigeration device 310 adjusts the infrared radiation emissivity of the surface coating according to T 33 (at this time, since the peltier cooler 210 is already turned off, there may be a situation of insufficient heating, and therefore, the radiant refrigeration device 310 adjusts the emissivity according to the value of T33 to adapt to the heating requirement), when T 33 is still greater than T 55 after the radiant refrigeration device 310 adjusts the emissivity for the preset period (e.g., 1-5 minutes), it indicates that heating is not needed, and the heating mode is turned on by mistake, and at this time, the heating mode is turned off.
In a preferred embodiment, heat exchanger 220 is configured as a phase change heat exchanger 221; in the heating mode, when T 33 is greater than a fifth set threshold T 55 (which is greater than 0), the phase-change heat exchanger 221 is heated in preference to the radiant refrigeration unit 310 to further conserve energy.
In a preferred embodiment, heat exchanger 220 is configured as a phase change heat exchanger 221; when the indoor coil 230 is closed and the electricity price is in the valley phase, one or more of an air conditioner end, the peltier cooler 210 and the radiation refrigerating device 310 can be started to realize the cold accumulation of the phase change cold accumulator; and when the indoor coil 230 is opened and the electricity price is in the peak phase, the phase change regenerator is firstly opened to release cold. The invention can hook electricity price and time information, and can save energy by utilizing the phase change cold accumulator to store energy, balance power grid load, reduce the use cost of the system and improve economy.
In order to further improve the accuracy of regulation, the invention also improves the method for acquiring the indoor average temperature, and specifically, the method comprises the following steps:
acquiring indoor space distribution parameters and performing grid division on the indoor space; configuring room temperature sensors on each grid;
acquiring indoor average temperature T1 based on grid temperature, grid position and grid user number information;
The indoor average temperature T1 is
Wherein P 11...P1n is a user weight coefficient of each grid, X 11...X1n is a temperature weight coefficient of each grid, T 11...T1n is a detected temperature of each grid, and n is the number of grids.
The user weighting coefficient is 1-1.3, and the user weighting coefficient is positively correlated with the number of grid users; when the number of grid users is 0, the user weighting coefficient is 1, and the more the number of grid users is, the higher the user weighting coefficient is. In one embodiment of a specific application, the user weighting factor is 1.1 when the number of grid people is in the interval 1-3; when the number of the grid persons is in the 3-5 interval, the user weighting coefficient is 1.2; but when the number of grid persons is greater than 5, the user weighting coefficient is 1.3.
The temperature weighting coefficient is between 0.8 and 1.2, and is positively correlated with the distance of the grid from the air outlet position of the indoor coil 230, i.e., the farther the grid is from the air outlet position of the indoor coil 230, the higher the temperature weighting coefficient is set, and in one specific embodiment, the temperature weighting coefficient is 0.8 when the grid distance is within 1 meter; when the grid distance is in the range of 1-2m, the temperature weighting coefficient is 0.9; when the grid distance is in the range of 2-3m, the temperature weighting coefficient is 1; when the grid distance is in the range of 3-4m, the temperature weighting coefficient is 1.1; when the grid distance is greater than 5m, the temperature weighting coefficient is 1.2.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
