Description

Technical Field

[0001] The utility model mainly relates to the technical field of optical air conditioning, in particular to an optical air conditioning system. Background Art

[0002] Home air conditioning systems are generally divided into three types. The first type is multi-split and boiler floor heating. The multi-split system is used for cooling in summer and boiler floor heating in winter. The second type is dual-supply, fan coil units and floor heating. The ceiling fan coil is used for cooling in summer and floor heating in winter. The above two usage modes are consistent. In comparison, the first type has a low initial investment and low comfort. The second type is a water machine with a higher price, but the cooling and heating are softer. The third type is radiant air conditioning. The indoor fresh air is turned on all year round, and the radiant terminal is used for cooling in summer and heating in winter. The initial investment is high and the comfort is the highest. The advantages of radiant air conditioning are no wind, no dead corners, and no noise. There is no air conditioning equipment indoors, and there is no equipment operating noise. It generally uses ground air supply with a low wind speed, so there is no blowing feeling.

[0003] The essence of light air conditioning is to achieve the conduction of cold and heat through the principle of radiation through efficient low-temperature radiation terminals. The composition of the light air conditioning system is the outdoor host of the air source heat pump + indoor dehumidifier + ceiling radiation terminal. The current five-constant system of light air conditioning cannot solve the problem of opening windows in summer. The five-constant system refers to a control system that can maintain constant temperature, constant humidity, constant oxygen, constant quietness and constant cleanliness in the indoor environment. Opening windows may allow outdoor moisture to enter the room, affecting the indoor humidity control, and condensation may occur. Condensation may promote the growth of mold and bacteria. These microorganisms can cause allergic reactions and respiratory problems. Condensation will cause building materials such as wood and gypsum board to absorb moisture. Long-term moisture may cause the material to expand, deform, rot or lose strength. For metal window frames, condensation may also cause corrosion, affecting the service life and appearance of the windows. Utility Model Content

[0004] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. Specifically, the present invention mainly provides a light air-conditioning system to solve the technical problem raised in the above background technology that condensation will occur if the windows are opened during use.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A light air conditioning system includes an anti-condensation adjustment mechanism and a temperature control panel in a room, wherein the anti-condensation adjustment mechanism includes an air source heat pump main unit, a dehumidifier, a buffer water tank, a variable water temperature pump station and a manifold, and an outlet pipe for water outlet is provided between the air source heat pump main unit, the dehumidifier, the buffer water tank, the variable water temperature pump station and the manifold, and a return pipe for water return is provided between the air source heat pump main unit, the buffer water tank, the variable water temperature pump station and the manifold.

[0007] Furthermore, the housing of the temperature control panel includes a dew point temperature sensor and a temperature and humidity sensor.

[0008] Furthermore, the manifold includes a plurality of radiation plates, each of which includes a heat preservation plate, a graphite heat conducting layer is provided in the groove of the heat preservation plate, and a heat exchange pipe is embedded in the groove of the graphite heat conducting layer.

[0009] Furthermore, a panel is provided on the graphite heat-conducting layer, and the panel covers the groove of the insulation board.

[0010] Furthermore, a first valve is provided between the two outlet pipes of the dehumidifier.

[0011] Furthermore, a water supply pipe is provided on one side of the outer wall of the buffer water tank, and a second valve is provided on the water supply pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model realizes changing the radiation amount of the radiation panel by adjusting the supply or return water temperature through the arrangement of an air source heat pump main unit, a dehumidifier, a buffer water tank, a variable water temperature pump station, a manifold, a dew point temperature sensor, a temperature and humidity sensor, an export pipe and a return pipe, that is, changing the water temperature to change the temperature of the surface of the radiation panel, thereby radiating to the room temperature, regulating the temperature and humidity, and avoiding condensation on the radiation panel, so that the demand for opening windows can be met during the use of the air conditioner, and the problems caused by condensation can be effectively avoided. Compared with the existing water circulation structure, the utility model has a simpler structure with fewer spare parts, and reduces the potential malfunctions caused by too many equipment in the system.

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is 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.

[0022] Please refer to the attached Figure 1-3A light air conditioning system includes an anti-condensation adjustment mechanism 1 and a temperature control panel 2 in a room. The anti-condensation adjustment mechanism 1 includes an air source heat pump host 11, a dehumidifier 12, a buffer water tank 13, a variable water temperature pump station 14 and a manifold 15. An outlet pipe 3 for water outlet is provided between the air source heat pump host 11, the dehumidifier 12, the buffer water tank 13, the variable water temperature pump station 14 and the manifold 15. A return pipe 4 for water return is provided between the air source heat pump host 11, the buffer water tank 13, the variable water temperature pump station 14 and the manifold 15.

[0023] Air source heat pump host 11: provides energy for the system;

[0024] Dehumidifier 12: mainly used for indoor dehumidification in summer and rainy season, and controls the surface humidity of the radiation panel 16;

[0025] Buffer water tank 13: As a water storage technology for air conditioning systems, it increases the water source for small-scale system operation. The heat storage buffer function can solve the problems of system load fluctuations and frequent host startup, thereby achieving the purpose of extending equipment life and saving energy and electricity;

[0026] Variable water temperature pump station 14: This is the water mixing center, replacing the existing secondary heat exchange system, including plate heat exchangers, electric three-way valves, and circulating water pumps. This reduces the equipment room footprint. In summer, the indoor dehumidifier 12 has a supply and return water temperature of 7 / 12°C, and the radiant panel 16 has a supply and return water temperature of 16 / 19°C.

[0027] Manifold 15: Contains float flowmeter and thermoelectric valve (existing equipment, not shown in the figure) and is mainly used to ensure the hydraulic balance of each radiation plate 16 circuit and to even out the temperature of the radiation plates 16 in each branch.

[0028] The above structure changes the radiation amount of the radiation panel 16 by adjusting the supply water or return water temperature, that is, changing the water temperature to change the surface temperature of the radiation panel 16, thereby radiating to the room temperature, thereby controlling the temperature and humidity and preventing condensation on the radiation panel (for example, in winter when there is no dehumidification requirement, the room temperature can be raised by increasing the supply water temperature, and the indoor dehumidifier 12 cannot be turned on). This allows the need to open windows to be met during the use of air conditioning, effectively avoiding the problems caused by condensation, and also preventing the problems of traditional fan coil cooling that make people feel uncomfortable and noisy at the indoor air supply outlet, and the high temperature of floor heating in winter that makes the room hot and dry.

[0029] The specific operation is as follows: when the indoor humidity exceeds the set value (the set value is manually set, such as the relative humidity is between 30% and 60%), the indoor dehumidifier 12 automatically starts dehumidification; when cooling in summer, the air source heat pump host 11 is turned on, the dehumidifier 12 is turned on, and after the indoor dew point temperature (dynamically changing) drops to the specified temperature (manually set temperature), the radiation panel 16 starts cooling (the dehumidifier 12 is turned on synchronously during the cooling process); when the difference between the indoor air temperature and the set temperature (the temperature of the temperature control panel 2) is less than 1°C, the indoor dehumidifier 12 is turned off, and the radiation panel 16 continues to operate, and the windows can be opened at any time during this period. If the system detects that the difference between the indoor air temperature and the set temperature is greater than 2°C or the indoor humidity increases, and the dew point temperature is higher than the indoor air temperature and there is a risk of condensation, the indoor dehumidifier 12 is automatically turned on; when heating in winter, the radiation panel 16 is mainly turned on for heating. When the indoor temperature cannot reach the set temperature, the dehumidifier 12 turns on auxiliary heating;

[0030] The indoor dehumidifier 12 is turned on according to the difference between the indoor air temperature and the set temperature of the temperature control panel 2. When cooling or heating, if the indoor air temperature is higher or lower than the set temperature of the temperature control panel 2 by 2°C or the indoor humidity increases, the indoor dehumidifier 12 will start the rapid cooling or heating mode and automatically stop when the set temperature is reached;

[0031] The system of this project is designed to allow windows to be opened for short periods of time in the summer. Our tests have shown that even if the room temperature is slightly higher than the dew point, the top radiant panels 16 will still perform cooling work and no condensation will appear on the surface of the radiant panels 16. Even if the windows are opened for a long time, causing the indoor temperature to rise and the indoor air humidity content to increase accordingly, the indoor dehumidifier 12 will automatically turn on when the indoor humidity rises, thus avoiding the occurrence of condensation. However, this method is relatively power-consuming.

[0032] During cooling in summer, the air source heat pump main unit 11 sends 7°C water to the dehumidifier 12. The 12°C return water of the air source heat pump main unit 11 is mixed with the water in the buffer water tank 13 and sent to the variable water temperature pump station 14. The 16°C supply water after heat exchange in the variable water temperature pump station 14 is sent to the manifold 15 for cooling the radiation plate 16. The 19°C return water returns to the variable water temperature pump station 14, and the mixed return water returns to the buffer water tank 13. All the return water in the system returns to the air source heat pump main unit 11, forming a closed water circuit.

[0033] During winter heating, the air source heat pump main unit 11 sends 45°C water to the indoor dehumidifier 12. The 40°C return water from the dehumidifier 12 is mixed with the water in the buffer water tank 13 and sent to the variable water temperature pump station 14. The 35°C supply water after heat exchange in the variable water temperature pump station 14 is sent to the manifold 15 for heating the radiation panel 16. The 32°C return water returns to the variable water temperature pump station 14, and the mixed return water returns to the buffer water tank 13. All the return water in the system returns to the air source heat pump main unit 11, forming a closed water circuit.

[0034] Please refer to the attached Figure 2 A first valve 121 is provided between the two outlet pipes 3 of the dehumidifier 12, a water supply pipe 131 is provided on one side of the outer wall of the buffer water tank 13, and a second valve 132 is provided on the water supply pipe 131. The valve is used to control the on-off of the pipe.

[0035] Please refer to the attached Figure 1 and attached Figure 3 The shell of the temperature control panel 2 includes a dew point temperature sensor 21 and a temperature and humidity sensor 22. The sensors are used to detect the indoor temperature and humidity. The manifold 15 includes a plurality of radiation plates 16, each of which includes an insulation plate 161. A graphite heat-conducting layer 162 is provided in the groove of the insulation plate 161, and a heat exchange pipe 163 is embedded in the groove of the graphite heat-conducting layer 162. The heat exchange pipe 163 is mainly made of pex-A and 304 stainless steel. A panel 164 is provided on the graphite heat-conducting layer 162, and the panel 164 covers the groove of the insulation plate 161. The panel 164 can be made of various materials such as gypsum board, waterproof gypsum board, calcium silicate board, etc.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
