Abstract
Description
Technical Field
[0001] The present application relates to the field of temperature control systems, and in particular to a cold and hot balance system. Background Art
[0002] The heat and cold balance system is one of the commonly used temperature control systems in large public buildings. It is mainly used in public areas such as stations where it is not suitable to install air-conditioning systems.
[0003] The general hot and cold balance system mainly uses water as the medium. Pipes are pre-buried in the area where temperature control is required, and the temperature of the entire area is controlled by changing the temperature of the medium. Usually, low-temperature medium is introduced in the summer, and high-temperature medium is introduced in the winter to maintain the temperature in the area within a suitable range. Generally, the medium is mostly water, which uses the large specific heat of water, and uses a heating device to keep the water temperature constant, so as to facilitate temperature control in the area.
[0004] Another temperature control system is a multi-link temperature control system. It can mainly play the role of independent temperature control, breaking the defect of the original multi-link system that can only cool or heat at the same time. It is mainly realized by a two-way evaporator, which uses the heat in the cold-consuming end to provide heat for the heat-demanding end, and the cold in the heat-consuming end to provide cold for the cold-demanding end. The two-way evaporative heat exchanger switches to cooling or heating mode according to the cold and hot demand of the entire system to balance the cold and hot demand of the entire system. However, this method still requires electricity or other energy to provide power, and is still not energy-saving enough. Utility Model Content

[0033] The following is combined with Figure 1-Figure 5 This application is described in further detail.
[0034] The embodiment of the present application discloses a heat and cold balance system. It is used to adjust the temperature in a public space, such as a train station or an airport terminal. In this application, for the convenience of describing the public space, the public space is collectively referred to as area 1. The heat and cold balance system is installed in area 1 to adjust the temperature balance in area 1.
[0035] Reference Figure 1 The cold and hot balance system at least includes a water tank. The water tank is buried underground. The top of the water tank is open. When buried underground, a pit for accommodating the water tank needs to be excavated underground first, and the water tank is placed in the pit. Permeable concrete or permeable asphalt is paved on it so that precipitation can pass through the ground and fall into the water storage tank 2 to replenish the water in the water storage tank 2. The water in the water storage tank 2 can be kept relatively constant.
[0036] Reference Figure 1 The water tank can receive external water sources, so once the water in the water tank is too much, it is easy to overflow from the water storage tank 2. In order to avoid this phenomenon, a watering pump can be installed in the water tank, the watering pump is fixed at the bottom of the water tank and the water outlet of the watering pump is connected to a watering pipe, the watering pipe extends out of the stratum and is placed in the soil layer of the green belt. The watering pipe is buried in the soil layer and has watering holes on the outer wall. When the watering pump is turned on, the water in the water tank can be used as water for watering the green belt, so that the water level in the water tank is relatively constant.
[0037] Reference Figure 1, an independent water pump is also required to be set up in the water tank, and the water pump is connected through the circulation pipe 3. One end of the circulation pipe 3 is connected to the water outlet of the water pump, and the other end of the circulation pipe 3 is connected to the water tank. The circulation pipe 3 can be directly extended from the water tank to the area 1. The water pump pumps the water in the water tank to circulate in the circulation pipe 3. A heat exchange component 4 is also fixed on the water tank, and one end of the heat exchange component 4 is fixed on the water tank and the other end extends into the ground. By utilizing the small temperature change of the underground, the heat exchange component 4 is used to perform heat exchange to maintain the water temperature in the water tank 2 at a relatively constant state, and the water circulates in the circulation pipe 3 and performs heat exchange with the external environment, thereby keeping the temperature change in area 1 small and playing a role in regulating the temperature. And there is no additional heating component, so it is more energy-saving and environmentally friendly.
[0038] Reference Figure 1 and Figure 2 The heat exchange assembly 4 includes a plurality of heat-conducting rods 41, one end of which is inserted into the water storage tank 2 and the other end of which is inserted into the ground. In order to improve the thermal conductivity, heat-conducting grids 42 can be fixed at both ends of the heat-conducting rods 41. The side in contact with the underground soil layer increases the contact surface with the soil layer, thereby enabling better heat conduction, while the side in contact with the water in the water tank increases the contact surface with the water, thereby enabling faster heat dissipation. Since the heat-conducting rods 41 pass through the water tank, a hole needs to be opened in advance on the water tank, and a seal needs to be fixed on the inner wall of the hole. Conventional seals such as sealing rings are applicable to prevent water from leaking from the opening.
[0039] There is another embodiment of the heat exchange assembly 4, referring to Figure 3 and Figure 4 In this embodiment, a plurality of heat conducting sheets 43 are fixed on the inner wall of the water storage tank 2 and the heat conducting sheets 43 are inserted into the water in parallel with each other, and the other end of the heat conducting sheet 43 is inserted into the cavity pre-opened on the side wall of the water storage tank 2, and the heat conducting rod 41 is also inserted into the cavity and abuts against the heat conducting sheet 43 for heat conduction. More specifically, a heat transfer plate 46 can be arranged in the cavity, one end face of the heat transfer plate 46 is always abutted against the heat conducting sheet 43, and the other end of the heat transfer plate 46 is provided with a mounting hole corresponding to the position of the heat conducting rod 41 for mounting and fixing the heat conducting rod 41. This makes the entire heat exchange assembly 4 able to be disassembled and assembled on site, and the transportation and on-site assembly are more convenient and quick.
[0040] Reference Figure 3 and Figure 4 In this embodiment, the end of the heat conducting rod 41 inserted into the ground can be either a bare rod or a plurality of heat absorbing sheets 44 can be fixed thereon. The side in contact with the underground soil layer increases the contact surface with the soil layer, thereby enabling better heat conduction.
[0041] Reference Figure 1 and Figure 5, the circulation pipe 3 is evenly distributed in the area 1 and fixed on the inner wall of the area 1. Taking the station as an example, it can be fixed on the top, side wall and ground of the station. The section of the circulation pipe 3 between the water storage tank 2 and the area 1 can be wrapped with an insulation layer to reduce the heat loss in the circulation pipe 3. A number of heat sinks 45 are fixed on the inner wall of the area 1 (i.e., the top, ground and side wall), and the heat sink 45 is perpendicular to the inner wall. A number of heat sinks 45 are evenly distributed on the inner wall of the area 1, and gaps for inserting the circulation pipe 3 are provided between adjacent heat sinks 45. The circulation pipe 3 is inserted into the gap and the outer wall of the circulation pipe 3 abuts against the outer wall of the heat sink 45. The pipe in the area 1 dissipates heat by the heat sink 45, and the heat dissipation is faster.
[0042] The present application utilizes a heat exchange component 4 so that the liquid in the water storage tank 2 buried underground can be maintained at a relatively constant temperature, and then pumped into the circulation pipe 3 by a water pump, and transported to the area 1 by the circulation pipe 3 to adjust the temperature in the area 1, so that the temperature in the area 1 can always be in a relatively suitable range. In addition, the water storage tank 2 is underground, and the thermal insulation effect is good. Only the energy for driving the water pump is needed to achieve the temperature adjustment in the area 1, which is more energy-saving and environmentally friendly. Heat-conducting grilles 42 are added to both ends of the heat-conducting rod 41, so that the heat transfer effect is better, and the temperature of the liquid in the water storage tank 2 is more balanced, which can play a role in regulating the temperature in the area 1 regardless of the seasons. Since the water storage tank 2 is underground, there is basically no need for additional heating to ensure that the liquid in the water storage tank 2 is in a relatively constant temperature state, which consumes less energy and is more energy-saving and environmentally friendly.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
