Description

Technical Field

[0001] The utility model relates to the technical field of indoor temperature regulation, and particularly relates to a self-humidifying temperature regulation system. Background Art

[0002] In winter, civil places usually use air conditioners or water heating to meet the heating needs, while factory workshops mostly use air source heat pumps or hot water boilers with higher efficiency and lower cost to meet the heating needs. In order to improve the environmental comfort of factory workshops, humidifying equipment sometimes needs to be set up to cooperate with the heating system.

[0003] In the prior art, humidifying methods generally include two categories. The first category is to add water humidifying equipment (such as high-pressure micro-mist humidifying or wet film humidifying equipment) to the heating system to increase the humidity of the hot air flow delivered to the workshop and achieve the humidifying effect. The second category is to separately use electrode humidifying or electrothermal humidifying equipment to deliver water vapor to the workshop to achieve the humidifying effect. For example, the patent document with the application number CN202223128108.8 discloses an indoor temperature regulation device based on an electric boiler, which includes an installation box body. A water storage object is installed inside the installation box body. A first temperature sensor is also installed at the bottom end inside the installation box body. The other side of the installation box body is connected to an exhaust duct in a communicating manner. A second temperature sensor is installed at the inner end of the exhaust duct. A humidifier is arranged at the bottom end inside the other side of the installation box body. The output end of the humidifier is connected to a humidifying pipe, and the humidifying pipe is connected to a spray head. An installation component is arranged at the rear side of the installation box body.

[0004] The existing two categories of humidifying methods have different problems in industrial applications: The first category of methods supply water to the humidifying equipment through a tap water pipe. The water temperature is relatively low in winter, resulting in low humidifying efficiency. When the water temperature is lower than the dew point temperature of the air supply, further humidification of the air becomes more difficult. On the other hand, high-pressure micro-mist humidifying and wet film humidifying involve the endothermic evaporation of water, which will cause the temperature of the hot air flow to decrease. The second category of methods using electrode and electrothermal humidifying equipment have the problem of too high energy consumption. Especially in a workshop with a large space, humidifiers with a large humidifying capacity need to be equipped, greatly increasing the humidifying cost. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides a self-humidifying temperature regulation system, which has both heating and humidifying effects, and has a lower humidifying cost and a better humidifying effect, and can effectively meet the heating and humidifying needs of the production workshop.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A self-humidifying temperature regulation system, comprising a air supply mechanism, a heating mechanism and a humidifying mechanism. The air supply mechanism includes at least one air supply unit, and the air supply unit includes an air inlet section, a heating section, a humidifying section and an air supply section. The air inlet section is connected with an air inlet pipe. The heating section is provided with a heating coil. The humidifying section is provided with a water humidifying device. The air supply section is provided with an air supply fan. The heating mechanism includes a heat source, a heating pipeline and a heat exchanger. The heating pipeline is connected to the heating coil and the heat exchanger, and the heating pipeline is connected to the first channel of the heat exchanger. The humidifying mechanism includes a water source and a water supply pipeline. The water supply pipeline is connected to the heat exchanger and the water humidifying device in sequence in the conveying direction, and the water supply pipeline is connected to the second channel of the heat exchanger.

[0008] The utility model is specifically designed for the heating and humidifying requirements of factory workshops. First, the system uses a water source heat pump unit, an air source heat pump unit, a solar device, etc. with lower costs as the heat source to meet the heating demand. When the cold air flow in the air supply mechanism passes through the heating section, the heating coil connected to the heating pipeline heats the cold air flow to form a dry hot air flow, achieving the heating effect. Second, the water supply pipeline of the humidifying mechanism is connected to the second channel of the heat exchanger on the heating pipeline, so that the tap water in the water supply pipeline has a relatively high temperature when it reaches the water humidifying device. On the one hand, it promotes the evaporation of water, and on the other hand, it avoids a large drop in the temperature of the hot air flow due to the evaporation heat absorption process, while ensuring the heating and humidifying effects, especially having a good application effect in winter or areas with lower temperatures. In the utility model, the heating of cold air and the heating of tap water both come from the heating pipeline extended from the same heat source. The overall heating cost is not high, and the pipeline system has a simple structure and low installation difficulty, which is suitable for factory workshops. The water humidifying device refers to a device that increases the contact between water and the hot air flow and enables water to quickly evaporate into the hot air flow. For example, a spray device that can generate tiny droplets or a wet film humidifying device with a large specific surface area. This type of device does not require electricity consumption to evaporate water and has a low cost.

[0009] Further, a filtering section is also provided between the air inlet section and the heating section, and a filter is installed in the filtering section.

[0010] Further, the air inlet pipe includes a first air inlet pipe for introducing outdoor fresh air and a second air inlet pipe for returning indoor air.

[0011] Further, a first air valve and a second air valve are respectively provided on the first air inlet pipe and the second air inlet pipe.

[0012] Further, the humidifying mechanism further includes a water softening device, and the water softening device is arranged upstream of the heat exchanger.

[0013] Further, the humidifying mechanism further includes a pressure-bearing water tank, which includes a water inlet pipe connected to the heat exchanger and a water outlet pipe connected to the water humidifying device.

[0014] Further, a circulation pipe is also connected between the pressure-bearing water tank and the heat exchanger, and a circulation power pump is provided on the circulation pipe.

[0015] Further, a temperature sensor and a liquid level sensor are provided in the pressure-bearing water tank.

[0016] Further, the heating pipeline includes a heat supply pipe and a return pipe. A first loop and a second loop which are connected in parallel are communicated between the heat supply pipe and the return pipe. The heating coil is connected to the first loop, and the heat exchanger is connected to the second loop.

[0017] Further, a first control valve, a second control valve and a third control valve are respectively provided on the first loop, the second loop and the water supply pipeline.

[0018] In summary, the following beneficial effects can be obtained by applying the present utility model:

[0019] 1. The present utility model can use a water source heat pump unit, an air source heat pump unit, a solar device, etc. with lower costs as heat sources to meet the heating demand. On the one hand, it can heat the air flow to meet the indoor heating demand. On the other hand, it can heat the water supply pipeline to increase the temperature of the liquid reaching the water humidifying device, improve the water evaporation efficiency and avoid a large drop in the temperature of the hot air flow.

[0020] 2. In the present utility model, the heating of cold air and the heating of tap water both come from the heating pipeline extended from the same heat source. The overall heating cost is not high, and the pipeline system has a simple structure and low installation difficulty, which is suitable for factory workshops.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1

[0028] Referring to Figure 1 , this embodiment provides a self-humidifying temperature regulation system, which includes:

[0029] The air supply mechanism 1 includes an air supply unit 11. The air supply unit is divided into an air inlet section, a filtering section, a heating section, a humidifying section, and an air supply section arranged in sequence. The air inlet section is connected with a first air inlet pipe 111 for introducing outdoor air and a second air inlet pipe 112 for returning indoor air.

There is a pressure change after the water flow is heated, and the pressure-bearing water tank can reduce its impact and is convenient for regulating the water volume delivered to the water humidifying device 115.

In a further embodiment, a temperature sensor and a liquid level sensor can also be arranged in the pressure-bearing water tank; the water supply pipeline is used to connect the water source, the water softening device, the pressure-bearing water tank, and the water humidifying device in series. A third control valve 321 is also arranged on the part of the water supply pipeline between the pressure-bearing water tank and the water humidifying device.

[0032] The present utility model can achieve different purposes by changing the working states of the first control valve 223, the second control valve 224, and the third control valve 321: the state of the first control valve determines whether the air flow is heated and regulates the heating temperature of the air flow.

Through the cooperation of the above three control valves, various indoor temperature regulation requirements can be met.
