Description

Humidifiers using heating heat

technical field

The patent of the present invention relates to a humidifying device using heating heat energy, especially a humidifying device using heating heat energy to drive semiconductor thermoelectric power generation as power, which belongs to the field of energy-saving and environment-friendly air conditioning.

Background technique

Humidity is an important parameter of the air environment. The heating period in winter is the driest season of the year. The indoor air is drier and the sense of comfort decreases, which affects health and can lead to respiratory diseases in severe cases. In addition, static electricity caused by drying will bring safety hazards. In order to increase air humidity, it is often used to put wet towels on the heating radiator or sprinkle water on the ground, but the effect is minimal; there are a wide variety of humidifier products on the market, which can meet different humidification needs, but additional power consumption is required and there is a high price , safety and other unfavorable factors. At present, the humidification principles of electric heating, ultrasonic and fan are mainly used. Compared with the power consumption of several hundred watts of electric heating humidification, ultrasonic humidification and fan humidification are more energy-saving, and the power consumption is from ranging from a few watts to tens of watts.

Through the favorable conditions of heating itself, it is hoped to solve the contradiction between heating and drying (Sun Mingjian, Xi Xianjun. Application Analysis of Humidification and Heating System in Engineering Design, China Construction Information (Heating and Refrigeration Special Issue), 2005, 4: 84-87). So far, dozens of patents have been issued (ZL 02290199.X household radiator humidifier; ZL 200620025605.7 water-absorbing curtain heating humidifier; 201010000409.5 heating humidification method and device; 200910011473.0 humidifying radiator; 02155623.7 an ecological humidifier ) proposed a humidifier using heat energy for heating, but it is only a simple change in structure, and the humidification is achieved by heating the feed water through the heating radiator. Due to the low temperature, small evaporation area, and insufficient water vapor discharge capacity, effective humidification cannot be achieved; using evaporation curtains, etc. Increasing the evaporation area will affect the heat dissipation of the heating radiator itself and fail to improve the humidification effect; some overemphasize the auxiliary function and ignore the humidification capacity. Existing patent (ZL 03219195.2 hot water radiator humidifier) directly uses heating hot water as humidification feed water, which increases the temperature of humidification feed water, but the humidification capacity of the system is still not strong, and heating hot water often contains corrosion inhibitors or scale inhibitors It is not suitable for use as humidification water supply. The important thing is that taking heating hot water will endanger the entire heating network and affect the safe operation of heating equipment. The system is not practical.

In recent years, the emergence of a batch of high-performance thermoelectric conversion materials has provided the possibility for the large-scale application of thermoelectric power generation technology, which has advantages in the utilization of low-grade heat energy (Zheng Yihua, Ma Yongzhi, thermoelectric power generation technology and its application in the field of energy saving, energy saving Technology, 2006, 2(5): 142-146). Under the premise of satisfying the heat dissipation effect, installing a thermoelectric power generation device on the heating radiator can achieve the purpose of energy saving and efficiency enhancement. The output power can reach hundreds of watts, which is enough to drive the energy-consuming components required by the humidifier, such as water pumps. , fan, ultrasonic generator, etc. Existing patents (ZL 201020041160.8 thermoelectric power generation radiator; ZL 200910017292.9 an electric valve device for heating system; ZL 00100795.5 a thermoelectric battery for powering cold and heat meters (heat meters)) do not involve humidification function, only heating system Combined with the semiconductor thermoelectric power generation module, the hot end is heated by simple contact with the radiator or the outer wall of the heating pipe, and the cold end is naturally cooled by air. Both the heat dissipation problem of the cold end and the influence of heat transfer capacity such as contact thermal resistance are ignored, and the heat transfer effect is poor. These factors are precisely the decisive factors that affect the efficiency of temperature difference power generation and the utilization and conversion of heating heat energy, resulting in low heat utilization efficiency, low power generation, and poor technical feasibility.

At present, there are no relevant practical products and feasible solutions that use heating heat to drive semiconductor thermoelectric power generation to achieve effective humidification.

Contents of the invention

Aiming at the contradiction between heating and drying, existing humidification and extra power consumption, and insufficient humidification capacity by simply using heating heat energy, the purpose of this invention is to provide a heat source and cooling system that directly uses heating hot water and humidification feed water as semiconductor thermoelectric power generation. It is a device that drives the ultrasonic humidification type and fan humidification type humidifier with low energy consumption through the electric energy generated by it to realize effective humidification.

Because the room temperature is affected by the temperature of the heating hot water, the temperature of the cold source is affected by the temperature of the heat source, that is, the temperature of the cold source is directly proportional to the temperature of the heat source. Correlation, the temperature difference between the cold and heat sources can remain stable within the range of normal working conditions. Under normal circumstances, corresponding to the heating hot water temperature of 90°C, the indoor temperature is 20°C.

The thermoelectric power generation device is made of multiple sets of semiconductor thermoelectric power generation components connected in series and in parallel. Water cooler, the water heater and the water cooler are heat exchangers in the form of liquid chambers, micro-channels, and coils. What flows in the water heater is heating hot water as a heat source. The water cooler What flows in the center is the humidification feed water as a cold source. There is a temperature difference between the hot end surface and the cold end surface of the thermoelectric power generation device. The thermoelectric power generation device outputs electric energy.

In order to increase the humidification capacity, the humidification feed water is often formed into a water film and water droplets through a sprinkler to enhance mixing.

Although the technical solution of the present invention needs to lead out heating water from the heating circulation pipeline, the heating water will return to the heating circulation pipeline after being circulated by the water heater, and the heating energy is used instead of heating. Hot water will not affect and harm the heating network and equipment.

The humidification feed water supply device is realized by a water storage container, a water replenishment device and a pipeline, the water storage container is connected to the water cooler through the water replenishment device and the pipeline, the water storage container stores a certain capacity of humidification feed water, and the water replenishment device The quantitative supply of humidification feed water is realized. The humidification feed water in the water storage container flows through the water cooler to cool the cold end surface of the thermoelectric power generation device while its own temperature rises, realizing the preheating of the humidification feed water, and then supplying the humidification unit. After evaporation Humidify. There are various realization schemes for the water storage container, water supply device and pipelines. The limited condition is to meet the continuous and quantitative supply of humidification water supply. The water storage container can be placed at a high position. The water supply device relies on gravity and sets a valve to control the flow rate. It can be set unlimited The water storage container at the position realizes the power and flow control of the humidification feed water through the water pump and controller of the water supply device.

The energy-consuming components included in the humidifying device using heating heat energy include the ultrasonic generator involved in the humidifying unit, the blower, the water pump in the heating hot water and the humidifying feed water supply device, and the electromagnetic Valves and controllers, etc., are all provided with electric energy by the thermoelectric power generation unit.
