Especially, the technology is difficult to be applied to common residential houses and small rooms.
It is obvious that the prior art has certain defects.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1 to 2, an embodiment of the invention provides a cold radiation and fresh air water-air circulation system, which includes a water chilling unit 1, a first water pump 2, a condensed water-air integrated pipe 3, a water return pipe 4, a cold radiation pipeline 5, a fresh air unit 6, an air inlet pipeline 7, an air delivery pipeline 8, and an exhaust pipeline 9; the condensed water-gas integrated pipe 3 consists of a cold water pipe 23 inside and a gas pipe 24 hermetically wrapped outside the cold water pipe 23, so that air can pass through a space between the cold water pipe 23 and the gas pipe 24; an outlet of the water chilling unit 1 is connected with an inlet of a cold water pipe 23 of the condensed water gas integrated pipe 3, a first water pump 2 is connected between the water chilling unit 1 and the cold water pipe 23, an outlet of the cold water pipe 23 is connected with an inlet of a cold radiation pipeline 5, an outlet of the cold radiation pipeline 5 is connected with an inlet of a water return pipe 4, and an outlet of the water return pipe 4 is connected with an inlet of the water chilling unit 1; the air supply end of the fresh air unit 6 is connected with the inlet of a gas pipe 24 of the condensed water gas integrated pipe 3 through an air inlet pipeline 7, and the outlet of the gas pipe 24 is connected with an indoor air inlet through an air conveying pipeline 8; an indoor air outlet is connected with the air exhaust end of the fresh air unit 6 through an air exhaust pipeline 9.
Referring to fig. 2 in detail, the condensed water-gas integrated pipe 3 is a core component of the present invention, and applies the principle of a condenser pipe, and when the cold water pipe 23 outputs cold water required by cold radiation, fresh air passes through the gas pipe 24, so that moisture in the fresh air is condensed and liquefied under the action of the cold water pipe 23, and is collected, thereby achieving the dehumidification function. And the process is carried out in the process of outputting cold water, so that the system layout can be simplified, and the effects of effectively combining a fresh air system and a cold radiation system and reducing the equipment cost are achieved. Compared with the prior art, the invention is particularly suitable for small space inside civil buildings, and has the advantages of low cost, simple structure and higher controllability.
The specific working process is as follows: cold water produced by the water chilling unit 1 is pressurized and conveyed to the cold water pipe 23 in the condensed water gas integrated pipe 3 through the first water pump 2, fresh air pressurized and output by the fresh air unit 6 enters the gas pipe 24 through the gas inlet pipeline 7 and is contacted with the outer surface of the cold water pipe 23, moisture in the fresh air is condensed when meeting cold, the moisture is dripped to the bottom of the gas pipe 24 to be collected, moisture contained in the fresh air is reduced, and a dehumidification effect is achieved. Then the cold water in the cold water pipe 23 is continuously conveyed to the cold radiation pipeline 5 so as to supply cold to the indoor space; the fresh air in the air pipe 24 is delivered to the indoor through the air delivery pipe 8, so that the air quality of the indoor environment is changed, the fresh air is delivered, the humidity of the indoor environment is reduced, and condensation cannot occur indoors as long as the cold radiation pipe 5 is properly matched with the humidity of the indoor air. After the water in the cold radiation pipeline 5 is cooled, the water flows into the water chilling unit 1 again through the water return pipe 4, and a water circulation is formed. The old air in the room is exhausted out of the room through the exhaust pipeline 9 to form an air path circulation.
The cold radiation pipe 5 is actually a cold radiation plate or a similar heat exchange structure acting in a room, and the technical features of the present invention are mainly focused on the architecture of the whole water path and air path circulation, so the specific structure of the cold radiation plate is not the technical feature of the present invention making technical contribution, and is not limited herein.
In order to increase the contact area between the air in the gas pipe 24 and the cold water pipe 23 and increase the condensation efficiency, the cold water pipe 23 is preferably spirally or S-spirally curved inside the gas pipe 24. In addition, the bottom of the gas pipe 24 is preferably connected to a water collecting pipe 15, and the water collecting pipe 15 is connected to the outside, so that the moisture condensed in the gas pipe 24 is collected and discharged to the outside through the water collecting pipe 15. In addition, in order to ensure that the temperature of the medium liquid in each pipeline is not lost, it is preferable that the condensed water-gas integrated pipe 3 and the water return pipe 4 are coated with a heat insulating layer.
Preferably, the system also comprises a temperature adjusting device and a heat exchanger 13; the temperature control device is connected with a heat exchanger 13, and the heat exchanger 13 is arranged at the inlet of the cold radiation pipeline 5 and is in heat conduction connection with the cold radiation pipeline.
The temperature of the cold water output from the cold water pipe 23 directly determines the efficiency of the cooling. However, the temperature of water in the cold radiation pipe 5 is not always maintained at a low temperature level for the comfort of indoor personnel, and thus technical means for controlling the cooling temperature are required. If the cooling power needs to be reduced and the water temperature needs to be increased, two feasible methods are available: the power of the water chiller 1 is reduced, or the cold water is heated after being discharged to the outside of the cold water pipe 23.
Reducing the power of the chiller 1 is certainly a simple solution, however, the temperature of the water in the cold water pipe 23 will also increase, and the condensation and dehumidification effect of the fresh air will decrease, so that the solution can be used only when the humidity of the indoor air is satisfied.
The temperature adjusting device and the heat exchanger 13 are adopted to generate certain heat, so that the temperature of water output by the cold water pipe 23 is properly increased, and the cooling power can be reduced on the premise of not reducing the condensation dehumidification effect.
For the specific structure of the temperature adjusting device, preferably, the temperature adjusting device comprises a warm water unit 10, a second water pump 11 and a warm water pipe 12; the outlet of the warm water unit 10 is connected with a second water pump 11, the outlet and the inlet of the second water pump 11 are communicated through a warm water pipe 12, and the warm water pipe 12 is in heat conduction connection with a heat exchanger 13. The water heater unit 10 heats water to generate water with a certain temperature, and the water is pressurized by the second water pump 11 and is conveyed to the heat exchanger 13 through the warm water pipe 12, so that the temperature of cold water output by the cold water pipe 23 is properly increased. In order to cooperate with the working process, a first temperature detection module is arranged at the outlet of the cold water pipe 23; the indoor that cold radiation pipeline 5 acted on is equipped with humidity detection module and second temperature detection module to through detecting the temperature at corresponding node, thereby the work of cooperation attemperator. In addition, the warm water pipe 12 is preferably provided with a first water valve 14, so that the work of the temperature adjusting device can be conveniently interrupted when the water temperature is proper.
In order to further meet the control requirement of the system, a second water valve 19 is preferably arranged between the outlet of the cold water pipe 23 and the inlet of the cold radiation pipeline 5, and a third water valve 20 is preferably arranged between the outlet of the cold radiation pipeline 5 and the water return pipe 4; a circulating pipe 21 is preferably communicated between the cold water pipe 23 and the water return pipe 4, and a fourth water valve 22 is arranged on the circulating pipe 21.
This design is mainly considered: the cold water and the fresh air directly output through the condensed water-gas integrated pipe 3 do not necessarily meet the requirements of sufficient dehumidification and refrigeration at the same time. For example, when in the humid season, the air contains more moisture, and the system needs to focus on drying and dehumidifying the fresh air. Even if the capacity of the chiller 1 is set to a maximum, the fresh air in the gas line 24 may still be insufficient to be sufficiently dry. At this time, the second water valve 19 and the third water valve 20 can be closed, the fourth water valve 22 is opened at the same time, the cold water pipe 23 is temporarily cut off to supply cold water to the cold radiation pipeline 5, and the cold water output by the cold water pipe 23 directly flows to the water return pipe 4 through the circulating pipe 21, so that a condensation water channel special for condensing fresh air is formed. After the indoor air is sufficiently dried, the second water valve 19 and the third water valve 20 are opened, the fourth water valve 22 is closed at the same time, and the water supply of the cold water pipe 23 to the cold radiation pipeline 5 is recovered, so that the indoor cold supply is recovered. In addition, the function can also be used for the independent dehumidification function in wet weather.
Preferably, a straight pipeline 16 is communicated between the air inlet pipeline 7 and the air transmission pipeline 8, a first air valve 17 is arranged on the air inlet pipeline 7, and a second air valve 18 is arranged on the straight pipeline 16. The fresh air supplied by the fresh air unit 6 from the outside has two air paths which can be moved: through the inlet line 7 to the gas pipe 24 for condensation or directly through the feed-through line 16 directly into the room. The air refreshing device is applied when cooling is not needed indoors, so that the fresh air system can work independently, is commonly used in cool autumn and winter, and is only used for keeping indoor air fresh.
Whether the fresh air needs to be dehumidified or not, a filter device is preferably arranged in the fresh air handling unit 6, so that dust particles and bacteria contained in the fresh air are reduced. On the one hand, the quality of indoor air can be improved, on the other hand, the circulating cleanliness of the air path can be improved, and the maintenance requirements are reduced.
According to the cold radiation and fresh air water-gas circulation system, cold water required by cold radiation is conveyed through the condensed water-gas integrated pipe 3, and fresh air is assisted to condense and dehumidify, so that a fresh air system and a cold radiation system are effectively combined into a whole, the structure is simplified, and the cost is reduced. The method has good effect on the market popularization and application of the cold radiation technology, is particularly suitable for small indoor space with low requirement on control precision, and can effectively popularize the cold radiation technology in the civil field. The water condensed in the condensed water-gas integrated pipe 3 can be discharged through the water collecting pipe 15, so that the whole system is kept dry and is easy to maintain. The pipeline and the corresponding valve are reasonably arranged, so that the fresh air system and the cold radiation system retain the capability of independent work, and the system not only can be applied to cooling, but also can independently perform dehumidification, air purification and the like.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
