Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning equipment technology, specifically to a steam air conditioner that integrates a water purification system, combining a heating system and a clean water system into one unit to achieve multi-functional use. Background Technology
[0002] Traditional air conditioning systems rely on compressor circulation, resulting in high energy consumption; in cooling mode, indoor air humidity is low, leading to poor comfort; while traditional steam air conditioners have the following drawbacks during the heating process:
[0003] 1. Water quality safety hazards: The heating water tank needs to be replenished with water, but the existing water replenishment system usually uses tap water directly, which cannot provide clean water. When tap water is used for replenishment, the calcium and magnesium ions in the water can easily form scale in the storage tank and circulation pipeline, which leads to a decrease in heat exchange efficiency (the thermal efficiency can decrease by 20%-30% after long-term use). At the same time, it breeds bacteria and microorganisms, affecting the service life of the equipment and the health of users.
[0004] 2. Limited Functionality: Traditional steam air conditioners have limited functionality and cannot meet users' needs for clean water. The air conditioning system and the water supply system are completely separate, requiring users to purchase additional water purification equipment (such as RO water purifiers or bottled water dispensers), resulting in an increase in space occupancy of over 40%, and poor coordination between the equipment and water purification / replenishment. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a steam air conditioner integrating a water purification system. This solves the issues of existing steam air conditioners having limited functionality and being unable to provide clean water. By integrating a heating system with a clean water system, it achieves multi-functional use in one unit while ensuring water quality, providing users with convenient cold or hot water services and heating water supply. The specific solution is as follows: A steam air conditioner integrating a water purification system includes:
[0006] (a) Heat circulation system: including a liquid storage tank, a solenoid valve, a heater, and a heat exchanger, which are connected in sequence to the liquid storage tank outlet, the solenoid valve inlet, the solenoid valve outlet, the heater inlet, the heater outlet, the heat exchanger inlet, the heat exchanger outlet, and the first inlet of the liquid storage tank through circulation pipelines; it also includes a fan, the fan outlet of which is connected to the back side of the heat exchanger, and the fan drives the airflow to flow through the surface of the heat exchanger fins and exchange heat with the indoor air through the front air outlet of the heat exchanger;
[0007] (b) Water purification system: including a water purification supply unit, a multi-way valve, a normal temperature water circuit, a water heating module, and a hot water circuit, wherein the multi-way valve includes at least three ports:
[0008] The first interface is connected to the water purification supply unit;
[0009] The second interface connects to the liquid storage tank;
[0010] The third interface connects to the ambient temperature water circuit, allowing purified water to flow directly to the ambient temperature water outlet.
[0011] When hot water is required, a fourth interface may also be included, which is connected to the hot water circuit, and the purified water is heated by the water heating module until it reaches the hot water outlet.
[0012] The purified water supply unit is connected to the second inlet of the storage tank through a multi-way valve pipeline and replenishes the storage tank with circulating medium. The circulating medium undergoes a gaseous and liquid phase change under the action of the heater and heat exchanger. The purified water supply unit is connected to the normal temperature water circuit through a multi-way valve pipeline and provides normal temperature purified water to the outside. The purified water supply unit is also connected to the hot water circuit through a multi-way valve pipeline and provides heated purified water to the outside through the water heating module.
[0013] Furthermore, it also includes a system controller: connected to the fan and the solenoid valve, used to control the speed of the fan and control the liquid storage tank to replenish the heater with circulating medium, the circulating medium being water.
[0014] Furthermore, the water supply unit includes a detachable pre-packaged water purification container and / or an external water source inlet pipe with a water purification filter assembly.
[0015] Furthermore, the water filtration and purification assembly includes at least one or a combination of reverse osmosis membrane, activated carbon filter, and ion exchange resin.
[0016] Furthermore, the storage tank is equipped with a water level detection switch, which triggers the water purification system to replenish the storage tank with circulating medium when the liquid level is lower than the threshold.
[0017] Furthermore, the heat exchanger includes a condenser or an evaporator, which is a multi-fin heat exchanger with the fin surface covered with a hydrophilic coating (contact angle ≤10°) or an antibacterial coating.
[0018] Furthermore, the heater includes a steam generator, an electromagnetic heating device, a resistance heating device, or an oil heater with an operating temperature range of 70-300°C.
[0019] Furthermore, the fan includes a DC inverter fan or an AC inverter fan, the speed of which is automatically adjusted by the system controller according to the indoor temperature.
[0020] Furthermore, the heater is a frequency converter, and its output power is adjusted by the system controller according to the indoor temperature and heat exchange requirements.
[0021] Furthermore, it includes an indoor temperature sensor for detecting the indoor temperature of the environment in which the device is placed.
[0022] Furthermore, the circulating medium undergoes a gaseous and liquid phase change under the action of the heater and heat exchanger: the liquid medium is output from the storage tank → the heater heats it to generate steam → it exchanges heat with the indoor air through the heat exchanger and releases heat to liquefy → it returns to the storage tank.
[0023] The beneficial effects that can be achieved through the above scheme include:
[0024] 1. Structural Innovation Benefits: Through the reuse design of the water supply unit, the same water source can simultaneously supply the storage tank and the water distribution unit, reducing the purchase cost of independent water purification equipment and saving installation space. The three-interface distribution structure (normal temperature water / hot water / storage tank replenishment) enables differentiated water supply and optimizes the pipeline topology.
[0025] 2. Water quality safety guarantee: Through multi-stage filtration technology of the water purification components, the water quality standard is improved, making direct drinking water safer.
[0026] 3. Energy Efficiency Improvement Innovation: The heat exchanger features an enhanced design with hydrophilic coated fins (contact angle ≤10°) that accelerate water flow and improve heat exchange efficiency. The DC / AC inverter fan dynamically adjusts its speed based on room temperature, making it more energy-efficient than a fixed-frequency fan.
[0027] 4. Optimized operation and maintenance costs: The water level detection switch is linked to the solenoid valve to achieve automatic water replenishment, avoiding the risk of dry burning and extending the life of the heater. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0035] Comprehensive combination Figures 1 to 4 As shown, a steam air conditioner integrating a water purification system includes:
[0036] (a) Thermal circulation system 100:
[0037] The thermal circulation system includes a storage tank 1, a solenoid valve 2, a heater 3, and a heat exchanger 4, which are connected in sequence to the storage tank outlet 13, the solenoid valve inlet 21, the solenoid valve outlet 22, the heater inlet 31, the heater outlet 32, the heat exchanger inlet 41, the heat exchanger outlet 42, and the first inlet 11 of the storage tank via circulation pipelines.
[0038] The heat exchanger 4 includes a condenser or an evaporator, which is a multi-fin heat exchanger. The fin surface is covered with a hydrophilic or antibacterial coating. The contact angle of the hydrophilic coating is ≤10°, which reduces the bio-adhesion ability on the fin surface.
[0039] The heat circulation system also includes a fan 5, which is placed above the heater 2 along with the heat exchanger 4. The fan outlet is connected to the back side of the heat exchanger 4. The fan drives the airflow to flow through the surface of the heat exchanger fins and exchange heat with the indoor air through the front outlet of the heat exchanger 4. The fan 5 adopts frequency conversion technology and can automatically adjust the airflow according to the indoor temperature.
[0040] The circulating medium undergoes the following phase change from gaseous to liquid under the action of the heater and heat exchanger: liquid medium is output from the storage tank → heated into steam by the heater → liquefied by heat exchange with indoor air through the heat exchanger via a fan → returned to the storage tank.
[0041] Between the liquid storage tank 1 and the heater 3, there is also a solenoid valve 2, which controls the opening and closing of the circulating medium from the liquid storage tank 1 to the heater 3.
[0042] (b) Water purification system 200: including a purified water supply unit 6, a multi-way valve 7, a normal temperature water circuit 81, a water heating module 84, and a hot water circuit 83, wherein the multi-way valve 7 includes at least three ports:
[0043] The first interface 71 is connected to the water purification supply unit 6;
[0044] The second interface 72 is connected to the second inlet 12 of the liquid storage tank;
[0045] The third interface 73 is connected to the ambient temperature water circuit 81, and the purified water flows to the ambient temperature water outlet 82.
[0046] When hot water is required, a fourth interface 74 may also be included, which is connected to the hot water circuit 83. The purified water is heated by the water heating module 84 and then flows to the hot water outlet 85.
[0047] The ambient temperature water circuit and the heating water circuit each have a switch to control the opening and closing of the water outlet.
[0048] It also includes a system controller 9: connected to the fan 5 and the solenoid valve 2, used to control the speed of the fan 5 and control the liquid storage tank 1 to replenish the circulating medium to the heater 3. The system controller 9 in this utility model can be a system controller in the prior art or other system controllers that can implement this utility model. This application mainly protects the overall structural composition and connection relationship of the steam air conditioner. The control connection of the specific circuit inside the system controller can adopt the connection method of the prior art or other connection methods.
[0049] The circulating medium is water.
[0050] The purified water supply unit 6 includes a detachable pre-packaged purified water container and / or an external water source inlet pipe with a filtration and purification component. Specifically, the detachable pre-packaged purified water container can be a pre-packaged bottled purified water 61. When the purified water supply unit 6 is an external water source inlet pipe with a filtration and purification component, it is connected to external tap water through the filtration and purification component 62. The filtration and purification component 62 includes at least one of the following: a reverse osmosis membrane, an activated carbon filter, and an ion exchange resin, or a combination thereof. More preferably, it uses a combination of an RO membrane (desalination rate ≥98%) and activated carbon (residual chlorine adsorption rate 99%). The filtration and purification component 62 is connected in series between the first port 71 of the multi-way valve 7 and the external tap water pipe to ensure that the incoming water is filtered and purified before being distributed into the equipment.
[0051] Meanwhile, the liquid storage tank 1 is equipped with a water level detection switch 14, which triggers the water purification supply unit to replenish water to the liquid storage tank when the liquid level is lower than the threshold.
[0052] The fan 5 includes a DC inverter fan or an AC inverter fan, and its speed is automatically adjusted by the system controller 9 according to the indoor temperature.
[0053] The heater 3 includes a steam generator, electromagnetic heating device, resistance heating device, or oil heater with an operating temperature range of 70-300℃. Furthermore, the heater 3 is a heater with frequency conversion function, and the system controller 9 can control the output function of the heater through voltage.
[0054] The steam air conditioner also includes an indoor temperature sensor 92, which is used to detect the indoor temperature of the environment in which the equipment is placed and to feed the temperature value back to the system controller.
[0055] An implementation scheme for a steam air conditioner with an integrated water purification system allows for the selection of two options: a detachable pre-packaged water purification container (i.e., bottled purified water) and an external water source inlet pipe with a filtration system. These options can be used separately or integrated into the steam air conditioner. Users can choose to use bottled purified water for water replenishment or use an external water source with a filtration system, such as tap water, which is filtered before replenishment. This flexible approach allows users to choose according to their preferences, increasing the ease of use of the equipment.
