[0001] The invention relates to an ice and hot water pipeline exhaust concentration system, belonging to the technical field of air conditioning. Background Art

[0002] The water temperature about 15 meters underground is usually kept at about 18 degrees, and the water temperature is relatively constant. In areas with sufficient water resources, water air conditioning (also known as water-cooled air conditioning) can be used to circulate groundwater. In summer, water is pumped up with a water pump and passed through the indoor fan coil to achieve the purpose of cooling. The return water flows back to the ground through the pipe. In winter, this cycle can also be used to achieve the purpose of heating.

[0003] Generally, after the air conditioning system pipeline is completed, water is added to the pipeline or there is a water leakage problem in the ice and hot water pipeline system, which makes maintenance difficult. When replenishing water, air can easily enter the pipeline and accumulate at the high points or bends of the pipeline, which will hinder the normal flow of water and cause pipeline blockage.

[0027] Please refer to Figure 1 The ice and hot water pipeline exhaust concentration system 100 shown in one embodiment of the present application includes: an outdoor unit 110, an indoor unit (not shown), a water circulation loop 120 and an exhaust water collection component 130. It is used in air conditioning systems to replace the refrigerant circulation for cooling or heating in some suitable occasions.

[0028] The indoor unit is connected to the outdoor unit 110 by a pipeline to form a water circulation loop 120; both the indoor unit and the outdoor unit 110 are provided with a heat exchanger, and a conventional refrigerant circulation loop is formed between the two, and the refrigerant circulation loop realizes heat exchange through two. This is the prior art and will not be described in detail here.

[0029] The exhaust water collection component 130 includes a water collector 132, an exhaust pipe connected between the water collector 132 and the air storage section of the water circulation loop 120, and a switch valve 134 arranged on the exhaust pipe. The air storage section is the highest point and / or corner of the pipe. The pipes of the water circulation loop 120 are all laid along the walls of the room, and are not extended in one direction. Therefore, there are many corners and high points higher than other pipes in the water circulation loop 120. After the air enters the water circulation loop 120, it will basically accumulate here. Over time, a large amount of air will accumulate in these places to form an air storage section. The accumulated air cannot be discharged, and too much accumulation will cause poor water circulation in the pipe, or even blockage.

[0030] In this embodiment, a transparent tube 136 for observing the condition in the exhaust duct is provided on the exhaust duct, and the transparent tube 136 is provided near the water collector 132. The water collector 132 is provided on the ground at a moderate height to ensure that the installation height of the transparent tube 136 is within the visual range of the staff, so that the staff can observe whether the exhaust gas or water is currently discharged from the exhaust duct, and the water quality of the currently discharged water.

[0031] In this embodiment, the end of the exhaust pipe connected to the gas storage section is arranged in the vertical direction. By setting the end of the exhaust pipe connected to the gas storage section as a vertical pipe, the air in the gas storage section is facilitated to naturally rise, thereby facilitating the complete exhaustion of the air in the water circulation loop 120.

[0032] In this embodiment, a drainage port is provided on the water collector 132, and the drainage port is connected to the floor drain through a pipe. In the exhaust process, it is inevitable that part of the water in the water circulation loop 120 is discharged. Therefore, the water collector 132 is provided to collect the discharged water or directly discharge it through the floor drain.

[0033] In this embodiment, the water circulation loop 120 further includes a water pump 122, which is used to control the water flow rate of the water circulation loop 120. The water pump 122 has a water inlet end and a water outlet end, and a control valve is provided on the water inlet end and the water outlet end. By providing a control valve to control the on-off state of the water circulation loop 120, more refrigerant circulation is replaced by water circulation, so that while ensuring the heat exchange effect of the air-conditioning system, the utilization rate of energy can be effectively improved, thereby effectively reducing the energy consumption of the air-conditioning system.

[0034] In this embodiment, two groups of switch valves 134 are provided, and the two groups of switch valves 134 are respectively provided near the gas storage section and the water collector 132. The switch valve 134 can be a solenoid valve or a manual valve, and the exhaust process is controlled by the switch valve 134 to avoid affecting the normal operation of the water circulation loop 120.

[0035] In this embodiment, the water circulation loop 120 also includes a water replenishment component 140 for replenishing water, and the water replenishment component 140 includes a water supply source and a control valve arranged between the water supply source and the water circulation loop 120. Among them, the water supply source can be a water tank or a water storage tank, as long as the water supply source has a water storage function; it is understandable that those skilled in the art can set the specific structure of the water supply source according to actual usage requirements. In addition, the present invention does not impose any restrictions on the specific connection method between the water supply source and the water circulation loop 120. The water supply source can be directly arranged on the water circulation loop 120, or it can be arranged outside the water circulation loop 120 and connected to the water circulation loop 120 through a connecting pipe. Those skilled in the art can set it according to actual usage.

[0036] In this embodiment, the water circulation loop 120 also includes a water pressure detection member for detecting water pressure. The water pressure detection member can be a pressure sensor or a pressure gauge, which is used to detect the water pressure in the water circulation loop 120, prevent possible failures or leakages, ensure the stability of water flow, and thus ensure the heat exchange efficiency and the overall performance of the system. It is convenient to replenish water through the water replenishment component 140 when the water pressure is insufficient, and to exhaust and drain water through the exhaust and water collection component 130130 when the water pressure is too high, thereby ensuring the normal operation of the entire system.

[0037] In this embodiment, a water coil heat exchanger and a heat exchange fan are provided in the outdoor unit 110, the water circulation loop 120 is connected to the water coil heat exchanger and the outdoor unit 110, and the heat exchange fan is used to assist the water coil heat exchanger in heat exchange. By setting the heat exchange fan to adjust the speed according to the difference between the actual indoor temperature and the preset indoor temperature, that is, when the difference between the actual indoor temperature and the preset indoor temperature is large, the heating or cooling efficiency of the air-conditioning system can be improved by increasing the wind speed of the indoor fan, thereby further improving the heat exchange efficiency of the air-conditioning system.

[0038] Preferably, multiple groups of water coil heat exchangers and heat exchange fans can be arranged in a one-to-one correspondence, and multiple water coil heat exchangers are arranged in parallel. Multiple water coil heat exchangers can be arranged in different rooms to meet the heat exchange needs of users in different rooms.

[0039] In addition, a heater may be provided at the outdoor unit 110 to heat the water in the water circulation to improve the heating effect.

[0040] The beneficial effects of the present invention are as follows: the present application arranges an exhaust pipe at the highest point and / or corner of the water circulation loop to connect to the water collector, and uses the exhaust pipe to discharge the air accumulated at the highest point and corners of the water circulation loop, thereby solving the problem of poor water circulation in the water circulation loop caused by air accumulation at the highest point and corners of the water circulation loop.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
