detailed description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although each component in the drawings is drawn in a specific scale, this proportional relationship is only exemplary, and those skilled in the art can make adjustments as needed to adapt to specific applications

The cold and heat supply station provided by the present invention can prepare cold/heat medium at a set temperature, or provide cold/heat for cold/heat medium that needs cold/heat. And the cold and heat supply stations are distributed in unspecified places (that is, the cold and heat supply stations are distributed in various locations in the city). The distribution of cold and heat supply stations is evacuated a little. In this way, taking the air-conditioning clothing as an example, since the cooling and heat supply stations are distributed in multiple locations, the air-conditioning clothing only needs to be equipped with pipelines for storing cold/heating media, and there is no need to install a separate pipeline for the air-conditioning clothing. Equipped with "cooling/heating equipment". Specifically, since the air-conditioning clothing only has pipelines for storing cold/heating media, it is convenient for users to wear. When the air-conditioning clothing needs to "replenish energy" (it can be understood as: making the cold/heat medium in the air-conditioning clothing pipeline reach the set temperature), the wearer of the air-conditioning clothing only needs to go to the nearest cold and heat supply station to replenish the air-conditioning clothing. "Supplementary energy" is enough. The cold and heat supply stations distributed in various locations in the city provided by the present invention "replenish energy" for the air-conditioning clothes. On the one hand, it is not necessary to equip each air-conditioning clothes with a separate cold and heat source device, thereby simplifying the structure of the air-conditioning clothes; On the one hand, through the distribution of cold and heat supply stations to "replenish energy" for air-conditioned clothing, the use of air-conditioned clothing is no longer restricted by location, that is, the wearer of air-conditioned clothing can move freely within any range, which greatly facilitates the use of air-conditioned clothing. The users of air-conditioning clothes have laid a good foundation for the popularization and promotion of air-conditioning clothes.

The cold and heat supply station mentioned above can be a larger area with a certain floor area, or a small area similar to a station. According to the size of the cold and heat supply station, one or more cold and heat source devices are arranged in each cold and heat supply station. The cold and heat source equipment includes a refrigeration/heating cycle device, which prepares a cold/heat medium at a set temperature, or provides cold/heat for a cold/heat medium that requires cold heat.

Let's take a separate cold and heat supply station as an example to "replenish energy" for air-conditioning clothes in detail.

Referring to FIG. 1 , FIG. 1 is a schematic diagram of a cold and heat source device 2 in the cold and heat supply station performing “energy replenishment” for the air-conditioning clothes 1 . Wherein, the cold and heat source equipment 2 includes a compressor 21 , a first heat exchanger 22 , a second heat exchanger 23 and a reversing valve 24 arranged on a circulation pipeline. In this embodiment, the cold and heat source equipment 2 can be regarded as an air conditioner, and a throttling device 26 is also arranged on the circulation pipeline of the cold and heat source equipment 2. The cooling/heating principle of the cold and heat source equipment 2 will be described below.

Continuing to refer to Fig. 1, the first heat exchanger 22 is located in the heat exchange container 25, and the heat exchange container 25 has a liquid inlet 251 and a liquid outlet 252, and the first heat exchanger 22 can communicate with the cold/heat in the heat exchange container 25. Medium for heat exchange. One side of the second heat exchanger 23 is provided with a fan 27 to speed up the heat dissipation efficiency of the second heat exchanger 23 . Preferably, the above-mentioned components (compressor 21, first heat exchanger 22, second heat exchanger 23, reversing valve 24, heat exchange container 25, throttling device 26, blower 27) are located in the cold and heat source equipment 2 Inside the housing 20.

The air-conditioning clothing 1 has a pipeline 11 containing cold/heat medium. The pipeline 11 is coiled and arranged in the air-conditioning clothing. The inlet 111 and outlet 112 of the pipeline 11 can be exposed outside the air-conditioning clothing 1 or hidden in the air-conditioning clothing 1. Inside. In this embodiment, the inlet 111 of the pipeline 11 communicates with the liquid outlet 212 of the heat exchange container 25 , and the outlet 112 of the pipeline 11 communicates with the liquid inlet 251 of the heat exchange container 25 . Preferably, a circulation pump can also be set in the heat exchange container 25, so that the cold/heat medium in the pipeline 11 of the air-conditioning clothing 1 enters the heat exchange container 25 from the liquid inlet 251, and flows along the outlet of the heat exchange container 25. The liquid port 252 flows back to the pipeline 11 of the air-conditioning clothing 1 to realize the circulation of cold/heat medium in the air-conditioning clothing 1 and the heat exchange container 25 .

Continuing to refer to FIG. 1 , the reversing valve 24 in FIG. 1 is in the direction of the refrigeration cycle (the direction of the arrow in the figure is the flow direction of the refrigerant). The working principle of "replenishing energy" for the air-conditioning clothes 1 is: the high-temperature and high-pressure gas discharged from the compressor 21 enters the second heat exchanger 23 and releases heat, which turns into a liquid refrigerant, and the liquid refrigerant enters the first heat exchange through the throttling device 26 22, the liquid refrigerant absorbs the heat of the cold/heat medium in the heat exchange container 25 in the first heat exchanger 22, evaporates into a gaseous refrigerant, and is sucked by the compressor to start the next cycle. In this process, the heat of the cold/heat medium in the heat exchange container 25 is absorbed by the refrigerant in the first heat exchanger 22, so that the temperature of the cold/heat medium in the heat exchange container 25 is reduced, and the cold/heat after reducing the temperature The medium enters the pipeline 11 of the air-conditioning clothing 1. After several cycles, the temperature of the cold/heat medium in the pipeline 11 of the air-conditioning clothing 1 can reach the set temperature. At this time, the user can use the air-conditioning clothing 1 Take it cool. After the "energy replenishment" is completed, the inlet 111 and the outlet 112 of the pipeline 11 are separated from the liquid outlet 252 and the liquid inlet 251 of the heat exchange container 25 respectively. This "replenishment" method can quickly obtain cold/heat medium at a set temperature by exchanging heat between the cold/heat medium in the pipeline 11 of the air-conditioning clothing 1 and the first heat exchanger 22, thereby improving user experience.

The direction of the reversing valve 24 is the direction of the refrigeration cycle. After changing the direction of the reversing valve 24 to the direction of the heating cycle, the high-temperature and high-pressure gas discharged from the compressor 21 directly enters the first heat exchanger 22 and releases heat. The cold/heat medium in the container 25 absorbs the heat and the temperature rises, and the cold/heat medium after the temperature rise enters the pipeline 11 of the air-conditioning clothing 1. After several cycles, the pipeline 11 of the air-conditioning clothing 1 The temperature of the cold/hot medium can reach the set temperature. At this time, the user can use the air-conditioning clothing 1 to keep warm. After the "energy replenishment" is completed, the inlet 111 and the outlet 112 of the pipeline 11 are separated from the liquid outlet 252 and the liquid inlet 251 of the heat exchange container 25 respectively.

In the above-mentioned embodiments, the cold and heat source equipment 2 in the cold and heat supply station of the present invention "recharges" the air-conditioning clothes. In addition, the cold and heat supply station of the present invention can also use the cold and heat source equipment 2 to prepare cold/heat medium at a set temperature in advance, for example, the liquid entering the heat exchange container 25 in the cold and heat source equipment 2 The port 251 and the liquid outlet 252 are respectively communicated with a heat preservation device, so that the cold/heat medium in the heat exchange container 25 can circulate in the heat preservation device and the heat exchange container 25. During the cycle, the cold/heat medium and the second The heat exchange of a heat exchanger 22 makes the cold/heat medium reach the set temperature. When it is necessary to "replenish" the air-conditioning clothes, the cold/hot medium at the set temperature can be directly injected into the air-conditioning clothes, so as to realize the "replenishment" of the air-conditioning clothes more quickly.

In addition, the cold and heat supply station of the present invention is provided with a control unit, which is used to control the cold and heat source equipment in the cold and heat supply station. Preferably, each cold and heat source device is provided with a control unit; or several cold and heat source devices are jointly controlled by one control unit. Further, the cold and heat supply station is also equipped with a charging unit. When the user needs to use the cold and heat source equipment, the charging unit is used to detect whether the preset fee has been received, and send instructions to the control unit according to the charging situation to control the cooling and heating. The source device is turned on or kept off; or, this charging unit is used to record the expenses incurred during the use of the cold and heat source device, and it will be settled uniformly after the use is over.

Further details will be described below in conjunction with FIG. 2 .

As shown in FIG. 2 , the cold and heat supply station of the present invention includes multiple cold and heat source devices, and each cold and heat source device is provided with a control unit and a charging unit.

Preferably, the control unit can be arranged on each cold and heat source equipment in the manner shown in FIG. Therefore, cold and heat source equipment; several sub-control units can also be set in the cold and heat supply station, and each sub-control unit controls multiple cold and heat source equipment. These all do not depart from the protection scope of the present invention.

Preferably, the charging unit can be set on each cold and heat source equipment in the manner shown in Figure 1; it is also possible to set only one total charging unit at the cold and heat supply station, and the total charging unit can monitor each of the cold and heat supply stations. The use of one cold and heat source equipment; several sub-charging units can also be set at the cold and heat supply station, and each sub-charging unit monitors the use of multiple cold and heat source equipment. In addition, the charging unit can also be arranged outside the cold and heat supply station, for example, the charging unit is arranged on a cloud server for managing the cold and heat supply station, etc., all of which do not depart from the protection scope of the present invention.
