Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of air conditioning refrigeration technical field, specifically related to a water source multi-connected unit heat supply and cooling system. BACKGROUND

[0002] Multi-connected unit refrigeration system is also called multi-connected air conditioning unit, and its refrigeration system is a outdoor unit that can deliver refrigerant liquid to several indoor units through pipeline, and by controlling the refrigerant circulation amount of compressor and the refrigerant flow entering each heat exchanger in the room, the indoor cooling and heating load requirements can be met in real time. At present, there are many types of central air conditioning, but multi-connected unit system still occupies the main share of the market with its simple design, low initial investment, easy installation and other advantages.

[0003] The current market multi-connected unit system is divided into water source and air source according to the form of cold and heat source. The commonly used air source multi-connected unit in the market has the advantages of fast response speed, stable temperature control, simple system, easy installation and combination, etc. However, due to its great influence by external environmental factors, its energy efficiency is relatively low. Water source multi-connected unit combines the technical advantages of air source heat pump and water-cooled cold water system, and has the advantages of high energy efficiency and small land occupation. In particular, it can also be combined with other renewable energy sources for refrigeration and heating. Therefore, water source multi-connected unit has received more and more attention.

[0004] In the actual operation process of water source machine system, industrial waste heat, cooling tower, energy tower, surface water or other renewable energy sources can be used as the cold and heat source of water source multi-connected unit in summer and winter. However, various cold and heat sources have different problems. Cooling tower can only be used in summer, and needs to be matched with a boiler or other heat source. Energy tower uses anti-freezing liquid in winter, which has corrosion effect on pipeline, and has volatility if directly contacted with air. At the same time, due to the characteristics of large difference in cooling and heating load and low load rate of similar residential buildings, the use rate of air conditioning is relatively low in most cases, and the use of traditional water source heat pump multi-connected unit will result in high cost of cooling water delivery.

[0005] In addition, the existing water source machine system generally still uses the conventional top blowing method for air supply of indoor unit. This method has poor comfort brought by blowing air flow in winter, and its use rate in family is very low, which leads to indoor temperature much lower than the comfortable temperature range of human body in winter, which is not conducive to the daily life and health of residents.

The heat can be controlled to be transferred from the high-temperature hot fluid to the low-temperature cold fluid through the heat exchange tube wall, so that heat exchange is realized. The two fluids flow in a counterflow direction (for example, the hot fluid flows from right to left, and the cold fluid flows from left to right), the temperature difference is maximized, and the heat exchange efficiency is improved.

[0018] Further, a pull rod is transversely and fixedly arranged between the intermediate partition plates, and the pull rod is arranged at a position close to the tube wall around the partition plate.

When the external temperature is too cold, the air source heat pump unit can also be started to further heat the external heat exchange cycle, thereby avoiding the freezing of the cooling tower and better heating the indoor unit. The heat source utilization efficiency is improved. Therefore, the cold and heat regulation can be better realized, the cooling tower can be prevented from freezing in winter, and the corrosion and volatilization of the antifreeze to the pipeline can also be avoided.

[0030] The two parallel pipelines are connected to the external pipeline, and the outer end of the parallel pipeline forms an interface 30 connected to the outdoor unit of the building or user.

In the process, the fan is started to generate air flow to assist heat exchange. The cooling tower heat exchange efficiency is improved.

[0036] Wherein, the air source heat pump unit comprises an air source heat pump 20 and a shell-and-tube heat exchanger 18, the shell-and-tube heat exchanger comprises an elongated tubular shell 21, two cooling water interfaces 22 are arranged at two ends of the shell 21 and connected to external pipelines, a partition plate 23 is arranged at each end of the inner cavity of the shell 21, the two partition plates 23 are located between the two cooling water interfaces, a plurality of heat exchange tube bundles 24 are transversely and penetratingly arranged on the two partition plates 23, an air source heat pump interface 25 is arranged at each end of the shell between the two partition plates 23 and communicates with the inner cavity, and an intermediate partition plate 26 is arranged on the inner cavity of the shell between the two partition plates 23 in an up-and-down staggered manner, one end of the intermediate partition plate 26 is fixed on the inner cavity wall, and the other end is spaced from the inner cavity wall, and the air source heat pump interface is connected to the air source heat pump through a pipeline in which a shell-and-tube heat exchanger side circulating water pump 19 is arranged to form a cycle.

[0037] In this way, the shell-and-tube heat exchanger indirectly transfers heat through the heat exchange tube bundles, utilizes the baffle disturbance and countercurrent arrangement to realize high-efficiency heat exchange between two fluids. The cooling tower cold water (cold fluid) flows in the tube bundles, and the air source heat pump hot water (hot fluid) is in the shell side space outside the tube bundles, is guided to flow around the tube bundles in an “S” shape through the baffles, and forms a transverse scouring flow.

[0041] Wherein, the indoor unit is a floor-mounted wall-mounted lower delivery end 16. The temperature environment comfort of indoor heat exchange can be better improved.

[0042] The system can realize multiple working conditions, more specifically, summer working condition, i.e. water source multi-connected refrigeration, the water source multi-connected outdoor unit is a condenser, and low-temperature cooling water needs to be delivered to it for cooling. The water circulation is divided into two parts, cooling tower side water circulation and sanitary hot water storage tank side water circulation, so that the summer operation of the water source multi-connected unit is divided into two modes. Mode one: the cooling tower side water circulation and the sanitary hot water storage tank side water circulation are operated simultaneously. At this time, the cooling tower side heat exchange branch switch valve 10 and the sanitary hot water side heat exchange branch switch valve 11 are opened simultaneously. Mode two: only the cooling tower side water circulation is operated, and the sanitary hot water storage tank side water circulation is not operated. At this time, the cooling tower side heat exchange branch switch valve 10 is opened, and the sanitary hot water side heat exchange branch switch valve 11 is closed. When mode one is operated: the high-temperature cooling water of the water source multi-connected outdoor unit is cooled by the cooling tower side heat exchange device 08 and the sanitary hot water side heat exchange device 12 and the circulating water from the cooling tower unit 01 and the low-temperature water on the sanitary hot water storage tank 15 side, two heat exchange cycles occur. The hot water after being heated by the cooling tower side heat exchange device 08 is delivered to the cooling tower unit 01 by the external circulating water pump 07, and is cooled under the joint action of the fan 02, the spraying device 03 and the heat exchange filler 04, and then continues to be delivered to the cooling tower side heat exchange device 08 for outdoor unit cooling. The hot water after being heated by the sanitary hot water side heat exchange device 12 is delivered to the user's sanitary hot water storage tank 15 by the internal circulating water pump 14, and is used as the user's standby sanitary hot water. When mode two is operated, only the cooling tower side water circulation is operated. The refrigerant aspect: the cooling tower side heat exchange branch switch valve 10 is opened, the sanitary hot water side heat exchange branch switch valve 11 is closed, the compressed refrigerant high-pressure gas flows into the cooling tower side heat exchange device 08 and the sanitary hot water side heat exchange device 12 to be condensed and liquefied. Then, after the expansion valve 13, it is delivered to the floor-mounted wall-mounted lower delivery terminal 16 (indoor unit), and evaporates to cool. Since the water source multi-connected outdoor unit side water pump is distributed, when the load difference between different floors or different users is large or the building utilization rate is low, the circulating water pump can be started according to the actual use floor or user.

[0043] In winter, the water source VRF system is used for heating, and the outdoor unit of the water source VRF system is an evaporator. The warm water needs to be supplied to the outdoor unit. At this time, the switch valve 11 of the sanitary hot water side of the refrigerant cycle is closed, and the water circulation of the sanitary hot water side is not operated. The low-temperature water passing through the outdoor unit is heated and warmed by the cooling tower side heat exchange device 08, and continues to heat the outdoor unit. If the ambient temperature is higher than 5°C, the cooling tower can still use the filler to heat and warm the low-temperature water, and continue to heat the outdoor unit of the water source VRF system. In the hot summer and cold winter area, if the ambient temperature is lower than or equal to 5°C, to prevent the cooling tower from freezing and being unable to operate, the air source heat pump unit 05 is opened at this time. The device can absorb heat from the outside air, and through the shell and tube heat exchanger 18 arranged in the cooling tower outlet water pipe section, the heat is transferred to the circulating medium by the shell and tube heat exchanger side circulating water pump 19. Similarly, since the water source VRF system side cooling water circulating water pump is distributed, in the case that the load difference between different floors or different users is large or the building utilization rate is low, the circulating water pump can also be started according to the actual use floor or user in winter to reduce the energy consumption of the circulating water pump. In terms of refrigerant: the circulating medium of the outdoor unit is delivered to the floor-mounted wall-mounted lower delivery terminal 16 (indoor unit) through the refrigerant pipeline, to achieve the effect of indoor heating. Since the indoor high-temperature air rises in winter, the downward air supply mode can reduce the temperature gradient at different heights in the room and improve the comfort of the indoor personnel.
