Description

An internal circulation indoor temperature control system

Technical field

The invention belongs to the technical field of indoor temperature control, and relates to a temperature control system, specifically an internal circulation indoor temperature control system.

Background technique

With the continuous development of society, people’s requirements for the quality of life are gradually increasing, especially the requirements for the living environment. The requirements are mainly reflected in the comfort of the space environment. Among them, the regulation of the space environment temperature is the most prominent. Under the appropriate temperature, the space environment allows people to work, live and perform other activities comfortably.

At present, the most common indoor temperature adjustment devices mainly include split air conditioners, central air conditioners, electric heating, electric floor heating, water floor heating and radiators. Through the above types of temperature adjustment devices, different space environments can be made different. In the case of circumstance, the comfortable temperature of warm in winter and cool in summer is reached, which improves the comfort of people's work, living and activities. Although these types of temperature adjustment devices can make the space temperature reach a comfortable temperature, there are still problems such as single temperature adjustment function, slow heating or cooling speed, and insufficient temperature distribution in the space.

For example: split air conditioner and central air conditioner can cool and heat at the same time, but the indoor air is dry and the temperature is unevenly distributed, and it cannot be effectively dispersed to all corners of the room, resulting in slower temperature control in individual corners, resulting in uneven temperature distribution in the space Even, and because the air outlet of the air conditioner is at a high place in the room, although the air conditioner is heating, the temperature is gradually increased from high to low, so that the temperature at high places is often higher than that at low places, causing people to experience hot up and cold down Discomfort and high cost; radiators can increase the indoor temperature in winter, but because the floor heats slowly, the floor is still frozen for a long time, while electric heating, electric floor heating and water floor heating can increase the indoor temperature overall , But they all have the problem of single function, only heating but not cooling, so they often need to be equipped with air conditioners, and use them in summer, which invisibly increases the cost of living. In addition, due to the strong electromagnetic field and potential safety hazards in electricity use, People have bad feelings in use.

Hereinafter, the present invention will be further explained through examples in conjunction with the accompanying drawings, but not as a limitation to the invention.

In the structure shown in FIG. 1, the internal circulation indoor temperature control system provided by the present invention includes a fluid storage heating and cooling device and a controller. The fluid storage heating and cooling device includes a fluid storage tank 1 and is arranged in the fluid storage container. Generally speaking, the fluid storage tank 1 adopts a pressure tank structure, which helps to ensure the smooth operation of the fluid in the circulation process. The fluid storage tank 1 is equipped with an automatic exhaust valve 13, a pressure sensor, and a fluid storage tank 1. The output port of the water separator 5 is connected to the water separator 5 through the water outlet pipe 4. The water separator 5 is equipped with an automatic exhaust valve 13 and a pressure sensor. The output port of the water separator 5 is connected to two cold and heat exchange coils 7 The exchange coil is provided with a flow control valve 6 for controlling the flow of fluid and a fluid medium temperature sensor for sensing the temperature of the fluid medium.

A circulating pump 10 and a check valve 11 are provided on the return water pipe 12, and on the circulating pump 10 Set a speed sensor, and connect the external fluid input pipe 9 to the return water pipe 12 to ensure the smooth filling of the fluid when the fluid needs to be supplemented without affecting the stable operation of the system; the controller includes the control host 3 and the indoor temperature sensor , Set the control panel on the control host, and connect the control host and the indoor temperature sensor by wireless connection (that is, set a signal transmitter on the indoor temperature sensor and a signal receiver on the control host), which is convenient for installation. The control host 3 is separately Electrically connected to the fluid medium temperature sensor, pressure sensor, and speed sensor set on each component, the temperature signal sensed by the fluid medium temperature sensor, the pressure signal sensed by the pressure sensor, and the speed signal sensed by the speed sensor are all transmitted to the control host 3. The control host 3 is also electrically connected to the heater, the refrigerator, the flow control valve, and the circulating pump through the control circuit, and is used to control the start, close or adjust the working state of the heater, the refrigerator, the flow control valve, and the circulating pump.

Specifically, in order to achieve the purpose of remote control, after downloading, installing and registering the mobile terminal APP 2 that matches the control host 3 on the mobile phone through the network, the mobile terminal APP and the control host 3 are connected through the network, and can be passed on the mobile terminal APP. Network control system on and off, fluid heating temperature control, fluid cooling temperature control, etc. Remote access, remote management and remote control are performed on the present invention to realize the intelligent management and control of the present invention.

The working principle of the present invention is as follows:

When indoor cooling or heating is needed, input the corresponding temperature on the control panel (or through the mobile APP operation), start the system, indoor temperature sensor, fluid medium temperature sensor, pressure sensor, speed sensor detect indoor temperature and fluid After the medium temperature, fluid pressure, and circulating pump speed, the signal is sent to the controller, and the control host 3 adjusts the control output according to the collected real-time data (temperature data, pressure data, speed data, etc.) by comparing the setting parameters Control the working conditions of the corresponding functional components (heater, refrigerator, flow control valve 6, circulating pump 10) to control the cooling or heating process of the fluid medium, the circulation process of the fluid medium, and the cold and heat exchange plate The flow control process of the fluid medium of the tube, etc., realizes the fine control of the system operation process. During the period, the fluid medium exchanges energy with the working heat exchange area of the application scene in the cold-heat exchange coil through the physical process of heat absorption or heat release, so as to achieve the effect of cooling or heating up the working heat exchange area (office area or housing) of the application scene .

When implementing the present invention, the system of the present invention is suitable for the use of a small space area. In the application scenario of a large space area or multiple rooms, the present invention can be used as a subsystem, and multiple subsystems can be combined and expanded. Realization, a composite system is formed by combining multiple subsystems. The composite system can be divided into series mode (as shown in Figure 2), parallel mode (as shown in Figure 3) and mixed mode (as shown in Figure 4) according to the combination mode. . In the composite system, a control center 14 is set up, and a control panel is set up on the control center (or, download, install and register a mobile APP matching the control center 14 on a mobile phone via the network). Use the control panel or mobile APP to operate the system.

The working principles of the composite system and the system of the present invention are basically the same, and the working methods are slightly different. In a composite system, no matter whether it is connected in series or in parallel, any subsystem in the system can be turned on, turned off, or adjusted at any time according to user needs.

In a composite system, each subsystem can work independently, or several subsystems can work together. In other words, in a composite system, a certain subsystem is supplying heat, while other subsystems can work for cooling.

In a composite system, each subsystem can be uniformly deployed by the general control center, receiving general control data and issuing instructions to set and adjust the operating status of the parameters in the system, and can also customize the operating parameters and status of the subsystems independently. The running status will be synchronously fed back to the control screen of the general control center.

Specifically, when the general control center sets the entire system to the heating mode, all the subsystems receive the control data of the general control center, unify the setting parameters and operate in the heating mode. At this time, if a subsystem needs to adjust the heating temperature due to individual scenarios, the administrator can operate on the control host of the subsystem to refine the personalized data and operating status of the subsystem’s jurisdiction. This operation The state does not have to be a heating state, but can also be a cooling state. Conversely, when the general control center sets the entire system to cooling mode, individual subsystems can also be set to heating state individually.

This is the mixed operating state in the compound mode of the present invention. In this state, the general control center sends out control instructions to control the working mode of the linkage valve according to the setting status of each subsystem, so that the system meets the needs of individual customization.

In the case of hybrid hybrid system, the characteristic of the serial hybrid system is that the flow rate is relatively stable, but the temperature adjustment is easily affected by the working mode of the previous subsystem. When the temperature of the previous subsystem changes, it will affect the subsequent subsystems. Therefore, in order to maintain the working stability of each subsystem, it is necessary to install temperature and pressure sensors at the fluid outlet position of the front-stage subsystem, so that the latter-stage subsystem can fine-tune the parameters according to the outlet temperature and pressure to achieve the purpose of stable working conditions. ; The characteristic of the parallel composite system is that the pressure difference between the fluid inlet and the outlet is relatively stable, but when the parameters of a certain subsystem in the system are adjusted, it will affect all other subsystems in the system. Therefore, in the parallel system, it is necessary to control each The temperature and pressure sensors are installed at the outlet of the host, and the parameters of each host are adjusted by comparing the data of each outlet to achieve a stable working state.

The working heat exchange area of the application scenario of the present invention needs to be designed on site according to the specific application scenario. The cold and heat exchange coils are the heat exchange working surface of the system, and the cold and heat exchange coils are arranged at a certain interval in the indoor floor, wall panel or ceiling. The cold and heat exchange coils can be set to one or more channels, and their pipe diameter and length are related to the working power of the internal circulation indoor temperature control system terminal, related to the requirements of the application scene, the size of the application scene, and the heat preservation performance of the application scene. Related to the thermal conductivity of the working surface material;

The cold and heat exchange coil is the heat exchange working surface of the system. The construction of the cold and heat exchange coil is in the decorative panel of the patent number: ZL 2019 2 0675952.1 structure, which facilitates the construction, reduces the cost, and improves the heat exchange effect. The cold and heat exchange coil can also be constructed and installed in other pipelines that can make the fluid circulate smoothly.

The fluid medium involved in the present invention can be water, processed water products, and other saturated gases or oils.

The upgraded version of the present invention also supports linkage interaction with other smart devices, or sends control information to other smart devices through infrared, wireless or network methods, and controls the opening and closing of other devices. For example, the linkage between this system and the window control system: when the cooling or heating is started, the linkage control message is sent to close the window, and when the system is cooling or heating is off, the linkage control message is sent to open the window for ventilation, etc.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principles of the present invention, several improvements and modifications can be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
