Description

Technical Field

[0001] The invention relates to the field of heat exchange, and in particular to a heat exchange method of a coil heat exchanger. Background Art

[0002] Air conditioners can effectively adjust indoor temperature by cooling or heating. However, during the use of air conditioners, using air conditioners for cooling in summer will condense the moisture in the indoor air and discharge it outdoors, causing dryness. Therefore, room temperature is now also adjusted by heat exchangers. When heat exchangers adjust room temperature, they control the temperature of the heat exchange liquid or gas to increase or decrease the temperature in the room. However, after the existing heat exchangers are installed, they can only manually adjust the temperature and flow rate of the internal heat exchange liquid or gas to speed up or slow down the temperature change. When users enter the room, it is impossible to save energy while allowing users to reach a comfortable temperature as soon as possible. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a coil heat exchange method that can save energy and enable users to quickly feel a comfortable temperature.

[0004] One of the purposes of the present invention is achieved by the following technical solution:

[0005] A heat exchange method for a coil heat exchanger comprises the following steps:

[0006] Design the coil heat exchanger structure: multiple heat exchange components are arranged in a straight line, each heat exchange component is connected to the liquid inlet pipe through the first control valve, and each heat exchange component is connected to the liquid outlet pipe through the second control valve;

[0007] Installing the coil heat exchanger: installing the coil heat exchanger indoors and setting the indoor space and the installation position of the coil heat exchanger in the control system of the coil heat exchanger;

[0008] Calculate the number of heat exchange components that need to work: Calculate the number of heat exchange components that need to work based on the real-time indoor temperature and comfort temperature;

[0009] Planning path: Scan the room to obtain the position and height of indoor furniture and items, obtain the position of the user in the room, calculate the heat flow path of the heat exchange components at different positions when they are working according to the installation position of the coil heat exchanger, the position and height of the furniture and items, the position of the user in the room and the heat exchange properties, and obtain the position of the heat exchange component corresponding to the most energy-saving heat flow path;

[0010] Real-time control: adjust the quantity and position of the heat exchange components in real time according to the changes in the user's indoor position and the indoor temperature.

[0011] Furthermore, in the path planning step, the user's indoor position is obtained by installing an infrared sensor on the ceiling of the room.

[0012] Furthermore, in the path planning step, the position and height of indoor furniture items are obtained by installing radars on the indoor ceiling and side walls.

[0013] Furthermore, in the path planning step, the heat exchange properties include cooling and heating. When the heat exchange property is cooling, the cold air descends during the flow, and when the heat exchange property is heating, the warm air rises during the flow.

[0014] Furthermore, the coil heat exchanger heat exchange method also includes a standby step, which is located after the real-time control step. The standby step is specifically: when the real-time indoor temperature reaches a comfortable temperature, the coil heat exchanger stops working and is in a standby state.

[0015] Furthermore, in the path planning step, three-dimensional modeling is performed based on the indoor space, the installation position of the coil heat exchanger, and the position and height of indoor furniture items, target points are created based on the user's position indoors, and thermodynamic simulation is performed based on the three-dimensional model and the target point position.

[0016] Furthermore, the thermodynamic simulation is performed according to the three-dimensional model and the target point position, specifically: calculating the surface temperature distribution image of the heat exchanger when the heat exchange components at different positions are working, and performing mechanical simulation according to the surface temperature distribution image of the heat exchanger.

[0017] Furthermore, in the step of calculating the working quantity of the heat exchange component, the indoor real-time temperature is the average temperature from the indoor ground to 2m.

[0018] Furthermore, in the step of calculating the working quantity of the heat exchange component, the comfortable temperature is 15°-25°.

[0019] Compared with the prior art, the heat exchange method of the coil heat exchanger of the present invention obtains the position and height of indoor furniture and items, obtains the position of the user in the room by scanning the room, calculates the heat flow path of the heat exchange components at different positions when working according to the installation position of the coil heat exchanger, the position and height of the furniture and items, the position of the user in the room and the heat exchange properties, and obtains the position of the heat exchange components corresponding to the most energy-saving heat flow path; the number and position of the working heat exchange components are adjusted in real time according to the changes in the user's position in the room and the changes in the indoor temperature. Through the above steps, the coil heat exchanger can change the position and number of the working heat exchange components in real time according to the real-time position of the user and the furniture layout, so as to save energy and make the user feel comfortable in temperature quickly.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The present application discloses a coil heat exchanger heat exchange method for regulating the temperature of a sealed environment, such as a home, a restaurant, an office, etc. The coil heat exchanger heat exchange method can be used for both heating and cooling by controlling the temperature of a heat exchange liquid or gas.

[0026] See also Figure 1 as well as Figure 2 , a coil heat exchanger heat exchange method, comprising the following steps:

[0027] Design the coil heat exchanger structure: multiple heat exchange components 30 are arranged in a straight line, each heat exchange component 30 is connected to the liquid inlet pipe 10 through a first control valve, and each heat exchange component 30 is connected to the liquid outlet pipe 30 through a second control valve;

[0028] Install the coil heat exchanger: Install the coil heat exchanger indoors and set the indoor space and the installation position of the coil heat exchanger in the control system of the coil heat exchanger;

[0029] Calculate the number of heat exchange components in operation: Calculate the number of heat exchange components 30 that need to work based on the real-time indoor temperature and the comfort temperature;

[0030] Planning path: Scan the room to obtain the position and height of indoor furniture and items, obtain the position of the user in the room, calculate the heat flow path of the heat exchange components at different positions when they are working according to the installation position of the coil heat exchanger, the position and height of the furniture and items, the position of the user in the room and the heat exchange properties, and obtain the position of the heat exchange component corresponding to the most energy-saving heat flow path;

[0031] Real-time control: The number and position of the heat exchange components are adjusted in real time according to the changes in the user's indoor position and the indoor temperature.

[0032] Specifically, in the step of designing the coil heat exchanger structure, multiple heat exchange components 30 are in parallel structure, and the inlet of each heat exchange component 30 is connected to the liquid inlet pipe 10 through the first control valve, and the outlet of each heat exchange component 30 is connected to the liquid outlet pipe 30 through the second control valve, so that the temperature of the hot liquid or gas entering each heat exchange component 30 is roughly the same, which is convenient for subsequent thermodynamic simulation. Each heat exchange component 30 is controlled by the first control valve and the second control valve to control whether it works. When the first control valve and the second control valve are both open, the corresponding heat exchange component 30 works, and when the first control valve and the second control valve are both closed, the corresponding heat exchange component 30 does not work.

[0033] In the installation of the coil heat exchanger, since the coil heat exchanger is used for both heating and cooling, hot air rises and cold air falls, the coil heat exchanger cannot be set close to the ground like the existing radiator, and needs to be installed at a certain height. When the coil heat exchanger is installed, the installation height and installation position of the coil heat exchanger are determined, and the installation height, installation position and parameters of the coil heat exchanger itself are set in the system.

[0034] In the step of calculating the number of heat exchange components to be operated, the temperature difference is calculated according to the indoor real-time temperature and the comfortable temperature, and the heat or cold required to reach the comfortable temperature is calculated according to the indoor volume, so as to calculate the number of heat exchange components 30 to be operated according to the preheating time or precooling time. The indoor real-time temperature is the average temperature from the indoor ground to 2m. The comfortable temperature is 15°-25°.

[0035] In the path planning step, the user's indoor position is obtained by installing an infrared sensor on the indoor ceiling. In this application, the coil heat exchanger changes the position of the working heat exchange component 30 according to the user's position, so that the air around the user can reach a comfortable temperature as soon as possible. The position and height of indoor furniture items are obtained by installing radars on the indoor ceiling and side walls. The heat exchange properties include cooling and heating. When the heat exchange property is cooling, the cold air descends during the flow, and when the heat exchange property is heating, the warm air rises during the flow, so the heat exchange property affects the path planning. In the specific process of path planning, three-dimensional modeling is performed according to the indoor space, the installation position of the coil heat exchanger, and the position and height of indoor furniture items, and the target point is made according to the user's indoor position. Thermodynamic simulation is specifically: calculating the surface temperature distribution image of the heat exchanger when the heat exchange components at different positions are working, performing mechanical simulation according to the surface temperature distribution image of the heat exchanger, and calculating which of the heat exchange components 30 at different position combinations work to make the air around the user reach a comfortable temperature as soon as possible.

[0036] The coil heat exchange method also includes a standby step, which is located after the real-time control step. The standby step is specifically: when the indoor real-time temperature reaches the comfortable temperature, the coil heat exchanger stops working and is in a standby state. When the coil heat exchanger is in the standby state, the indoor real-time temperature monitoring device continues to work, and when the difference between the indoor real-time temperature and the comfortable temperature reaches a preset value, the coil heat exchanger starts working.

[0037] Compared with the prior art, the heat exchange method of the coil heat exchanger of the present invention obtains the position and height of indoor furniture and items, obtains the position of the user in the room, and calculates the heat flow path of the heat exchange components 30 at different positions when working according to the installation position of the coil heat exchanger, the position and height of the furniture and items, the position of the user in the room and the heat exchange properties, so as to obtain the position of the heat exchange components corresponding to the most energy-saving heat flow path; the number and position of the working heat exchange components 30 are adjusted in real time according to the changes in the user's position in the room and the changes in the indoor temperature. Through the above steps, the coil heat exchanger can change the position and number of the working heat exchange components in real time according to the real-time position of the user and the furniture layout, so as to save energy and enable the user to quickly feel the temperature comfortable.

[0038] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
