Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a conduction heat transfer air conditioning system which can directly transfer heat with a use object and reduce energy loss.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1-3, the conduction heat transfer air conditioning system provided by the present invention comprises a cold and heat source 5, a delivery pipe 4, a heat transfer medium 6 and a conduction heat transfer air conditioner 2.
Specifically, the conduction and conduction air conditioner 2 is in direct contact with the subject of use 1.
The cold heat source 5 is used to absorb heat or release heat at a set temperature.
A heat transfer medium 6 is arranged in the conveying pipeline 4. The heat transfer medium 6 is in heat transfer with the conduction heat transfer air conditioner 2 and/or the cold and heat source 5 during the process of flowing in the conveying pipeline 4.
Preferably, the conduction and heat transfer air conditioner 2 is made of metal or polymer material so as to conduct and transfer heat with the object 1 quickly.
In this embodiment, the cold and heat source 5 may be an air conditioner or a boiler, but is not limited thereto and may be adjusted according to actual needs.
Further, in order to control the temperature of the conduction heat transfer air conditioner 2 and improve the use experience of the user 1, the conduction heat transfer air conditioning system further comprises a cooling and heating controller 3, and the cooling and heating controller 3 is located on the conveying pipeline 4. The cooling and heating controller 3 is used for controlling the transmission speed of the heat transmission medium 6.
In order to realize more accurate control and regulation of the temperature of the conduction and heat transfer air conditioner 2, the cooling and heating controller 3 further comprises a temperature setting module, a temperature detection module and a control module.
The temperature setting module is used for setting and storing a target temperature value.
The temperature detection module is positioned on the conveying pipeline 4. The temperature detection module is used for detecting the temperature of the heat transmission medium 6 to obtain a detection temperature value. In the present embodiment, the temperature detection module is disposed at a distance of 50 cm from the conduction and heat transfer air conditioner 2, so as to obtain a detection temperature value closer to the temperature of the conduction and heat transfer air conditioner 2.
The control module is positioned on the conveying pipeline 4 and is respectively connected with the temperature setting module and the temperature detection module. The control module is used for controlling the transmission speed of the heat transmission medium 6 according to the target temperature value and the detected temperature value.
As a specific implementation manner of this embodiment, the temperature setting module is preferably an erasable memory; the temperature detection module is preferably a temperature sensor; the control module is preferably a control valve or a variable flow pump.
When the control module is a variable flow pump, the transmission speed of the heat transmission medium 6 in the conveying pipeline 4 is adjusted by adjusting the flow output by the variable flow pump.
In the heating mode, when the detected temperature value is lower than the target temperature value, the flow rate is increased by the variable flow pump to increase the speed of the heat transfer medium 6 flowing into the conduction heat transfer air conditioner 2; when the detected temperature value is higher than the target temperature value, the variable flow pump throttles the flow to reduce the speed at which the heat transfer medium 6 flows into the conduction heat transfer air conditioner 2. In the cooling mode, when the detected temperature value is lower than the target temperature value, the variable flow pump reduces the flow rate to reduce the speed of the heat transmission medium 6 flowing into the conduction and heat transfer air conditioner 2; when the detected temperature value is higher than the target temperature value, the variable flow pump increases the flow rate to increase the speed at which the heat transfer medium 6 flows into the conduction heat transfer air conditioner 2.
When the control module is a control valve, the transmission speed of the heat transfer medium 6 is controlled by controlling the area of the cross section of the heat transfer medium flowing inside the conveying pipeline 4. Meanwhile, in order to provide enough power for the heat transmission medium 6 so that the heat transmission medium can flow and exchange heat inside the conveying pipeline 4, and the overall heat exchange efficiency of the system is improved, the conveying pipeline 4 is further provided with a circulating pump 7, the circulating pump 7 is used for providing stable pressure for the heat transmission medium 6, and the pressure value is determined according to actual requirements.
Likewise, in the heating mode, when the detected temperature value is lower than the target temperature value, the control valve is adjusted to be large to increase the flow rate of the heat transfer medium 6 flowing into the conduction heat transfer air conditioner 2; when the detected temperature value is higher than the target temperature value, the control valve is adjusted to be small to reduce the flow rate of the heat transfer medium 6 flowing into the conduction heat transfer air conditioner 2. In the cooling mode, when the detected temperature value is lower than the target temperature value, the control valve is adjusted to be small so as to reduce the flow of the heat transmission medium 6 flowing into the conduction and heat transfer air conditioner 2; when the detected temperature value is higher than the target temperature value, the control valve is adjusted to be large to increase the flow rate of the heat transfer medium 6 flowing into the conduction heat transfer air conditioner 2.
Optionally, the control module is further connected to the cold heat source 5. The control module is also used for adjusting the set temperature of the cold and heat source 5 according to the target temperature value and the detected temperature value.
Taking the cold and heat source 5 as an air conditioner host as an example, the air conditioner host comprises a compressor, an evaporator, a condenser and a four-way valve, and realizes refrigeration or heating through the cooperation of the compressor, the evaporator, the condenser and the four-way valve, when the air conditioner host is used for refrigeration, the heat of the heat transmission medium 6 in the conveying pipeline 4 can be absorbed, and when the air conditioner host is used for heating, the heat can be released to the heat transmission medium 6 in the conveying pipeline 4.
In a heating mode, when the detected temperature value is lower than a target temperature value, the control module sends a corresponding control signal to the air conditioner host, and after the air conditioner host receives the control signal, the self-set temperature value is increased by controlling the starting of the compressor and the electrification of the four-way valve, and the temperature of the conduction heat transfer air conditioner 2 is increased under the action of the heat transmission medium 6; when the detected temperature value is higher than the target temperature value, the control module sends a corresponding control signal to the air conditioner host, the set temperature value of the air conditioner host is not increased any more by controlling the stop of the compressor and the power-off of the four-way valve, and the temperature of the conduction and heat transfer air conditioner 2 is not increased any more under the action of the heat transmission medium 6.
In a refrigeration mode, when the detected temperature value is lower than a target temperature value, the control module sends a corresponding control signal to the air conditioner host, the set temperature value of the air conditioner host is not reduced by controlling the stop of the compressor, and the temperature of the conduction and heat transfer air conditioner 2 is not reduced under the action of the heat transmission medium 6; when the detected temperature value is higher than the target temperature value, the control module sends a corresponding control signal to the air conditioner host, and after the air conditioner host receives the control signal, the air conditioner host controls the starting of the compressor to reduce the self-set temperature value and reduce the temperature of the conduction and heat transfer air conditioner 2 under the action of the heat transmission medium 6.
In addition, the invention also provides specific structures of several conveying pipelines 4:
the first embodiment is as follows: the delivery pipe 4 is communicated with the input end and the output end of the cold and heat source 5, and the delivery pipe 4 is arranged in contact with the conduction and heat transfer air conditioner 2 (as shown in fig. 1).
