Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, specifically to a high-low temperature dual-phase air conditioning energy-saving chiller unit. Background Technology

[0002] A refrigeration unit is a device that uses energy to transfer heat from a specific space or material to the outside, thereby cooling or maintaining a low temperature. Among them, the high and low temperature dual-phase air conditioning energy-saving chiller unit is a high-end refrigeration unit that can be adapted to air conditioning systems and achieve "independent dual-temperature supply + energy-saving operation".

[0003] In existing technologies, high and low temperature dual-phase air conditioning energy-saving chillers are devices with a dual-loop design. Therefore, their refrigerant charge is greater than that of traditional single-temperature units. At the same time, these chillers also have more pipe joints and valves. As a result, the risk of refrigerant leakage in these chillers is significantly higher than that in traditional units. Traditional high and low temperature dual-phase air conditioning energy-saving chillers rely heavily on ventilation to dilute leaked gaseous refrigerant, making it difficult to quickly collect and purify the leaked gas. In this case, the leaked refrigerant can cause problems such as global warming, soil and water pollution, injury to workers, and increased risk of safety accidents.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, by setting up a purification mechanism, it is possible to detect whether there is a refrigerant leak in the high and low temperature dual-phase air conditioning energy-saving chiller unit in a timely manner. When a refrigerant leak occurs, it can be collected and purified in a timely manner, thereby improving the utilization efficiency of the high and low temperature dual-phase air conditioning energy-saving chiller unit. When a refrigerant leak is detected in the chiller unit, the stop block is reset by the cooperation of the dual-shaft motor, screw rod and electromagnetic clutch, which can block all the square holes on one of the panels, so as to seal the space composed of two panels, two side plates, top plate, multiple bottom plates and main mounting bracket. Then, the stop bar is moved by the cooperation of electric push rod and control cabinet to release the corresponding air inlet on the air inlet pipe from being blocked.

[0019] 2. In this invention, by using a dual-axis motor, control cabinet, fan body, processing box, air inlet pipe, perforated cover, manifold, bend, branch pipe, and control valve to open the valve, the gaseous refrigerant in the sealed space consisting of two side plates, two front panels, top cover, main mounting frame, adsorption layer, exhaust pipe, and multiple base plates can be first extracted, then the gaseous refrigerant mixed in the air can be adsorbed and removed, and then transported back to the sealed space. At the same time, by using the control valve and electric push rod, the adsorption layer can be switched sequentially to meet the collection and purification treatment of large refrigerant leaks.

[0020] 3. In this invention, by setting up a chiller unit mechanism, dual-temperature independent supply and energy-saving operation can be achieved, thereby solving the demand for additional single units for differentiated refrigeration in different scenarios. When it is necessary to cool down precision loads or air conditioning loads through refrigeration, the control cabinet, variable frequency compressor, two first electric valves with open valves, condenser, two three-way pipes, first connecting pipe, second connecting pipe and electric throttle valve are used to convert the low-pressure gaseous refrigerant drawn from the return pipe into high-temperature and high-pressure gaseous refrigerant, then into high-pressure liquid refrigerant, and then into low-temperature and low-pressure mist refrigerant.

[0021] 4. In this invention, the heat carried by the cold water in the chilled water pipe cooling the precision load or air conditioning load can be absorbed by the evaporator, water pump, inlet pipe, water softener, arc pipe and filter, thereby achieving the cooling operation of the precision load or air conditioning load. At the same time, the low-temperature and low-pressure mist refrigerant will also be converted into low-pressure gaseous refrigerant and enter the interior of the return pipe for a new cycle. Simultaneously, by the control cabinet, temperature sensor and corresponding temperature threshold, the speed of the variable frequency compressor and the frequency of the water pump can be controlled, thereby avoiding high-intensity power consumption and achieving energy saving. When the building is heated, the building heating needs can be guaranteed by the heat exchange principle through the cooperation of the variable frequency compressor, control cabinet, two second electric valves with open valve, connecting pipe, electric throttle valve, evaporator, water pump and the previously linked components.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-5 and Figure 9As shown, the present invention provides a technical solution: a high and low temperature dual-phase air conditioning energy-saving chiller unit, including a chiller unit mechanism 1. The chiller unit mechanism 1 includes a main mounting frame 101. A control cabinet 102 is installed on the front of the main mounting frame 101 near the top. Two variable frequency compressors 103 are installed on the top of the main mounting frame 101. Two hanging brackets 104 are fixed to the top of the inner wall of the main mounting frame 101. A condenser 105 is installed between each hanging bracket 104 and the main mounting frame 101. An auxiliary mounting frame 107 is fixed to the bottom of the inner wall of the main mounting frame 101. Two symmetrical evaporators 108 are installed on the top of the auxiliary mounting frame 107. An electric throttle valve 109 is connected to the liquid inlet end on the side of each evaporator 108. The middle of the outer wall of each condenser 105 is... Each condenser 105 has a first electric valve 111 connected to both its inlet and outlet ends. A three-way pipe 112 connects the inlet and outlet ends of each first electric valve 111. One port of each three-way pipe 112 connects to a second electric valve 113. A connecting pipe 114 connects the two second electric valves 113 on each condenser 105. Each variable frequency compressor 103 has a first connecting pipe 115 and a return pipe 106 connected to its outlet and inlet ends, respectively. Two symmetrical water pumps 116 are mounted on the crossbeam inside the main mounting frame 101. Each water pump 116 has a delivery pipe 117 and an inlet pipe 118 connected to its inlet and outlet ends, respectively. The outlet end of each delivery pipe 117 connects to the outer surface of each evaporator 108. The water inlet ends at the middle of the wall are connected. Each water inlet pipe 118 is connected to a water softener 119. Each water softener 119's inlet end is connected to an arc-shaped pipe 120. Each arc-shaped pipe 120's detection end is connected to a temperature sensor 121. Each arc-shaped pipe 120's inlet end is connected to a filter 122. Each electric throttle valve 109's liquid inlet end is connected to a second connecting pipe 123. The air outlet end of each first connecting pipe 115 is connected to the other port of one of the three-way pipes 112 on the corresponding condenser 105. Each second connecting pipe 123 is connected to the other port of the other three-way pipe 112 on the corresponding condenser 105. The air inlet end of each return pipe 106 is connected to each evaporator 10. The side air outlets of 8 are connected, and the water outlet at the middle of the outer wall of each evaporator 108 is connected to a water outlet pipe 110. A purification mechanism 5 is installed on the main mounting frame 101. The purification mechanism 5 includes two panels 501, two side panels 504, and a treatment box 509. A box cover 511 is installed on the top of the treatment box 509, and a dual-shaft motor 512, a fan body 513, and an electromagnet 515 are also installed on the inner surface of the through hole on it. The air outlet and air inlet of the fan body 513 are connected to an exhaust pipe 519 and an air inlet pipe 520, respectively. A rubber pad 2 is glued to the bottom of the main mounting frame 101. Multiple first fixing brackets 3 and multiple second fixing brackets 4 are fixed on the main mounting frame 101. The first fixing brackets 3 are used to fix the delivery pipe 117 and the water softener 119.The second mounting bracket 4 is used to secure the water outlet pipe 110 and the vent pipe 519.

[0034] In this embodiment, during refrigeration, parameters such as the rotation speed of the two variable frequency compressors 103, the opening degree of the two electric throttle valves 109, the concentration threshold, and the temperature threshold are first set on the control cabinet 102. Simultaneously, the two first electric valves 111 on one of the condensers 105 are opened, and then the variable frequency compressor 103 is started. The started variable frequency compressor 103 draws in the low-pressure gaseous refrigerant returned from the return pipe 106. The drawn-in low-pressure gaseous refrigerant is first converted into a high-temperature, high-pressure gaseous refrigerant, and then transported to the inside of the first connecting pipe 115 through one of the three-way pipes 112 and the corresponding first electric valve 111 that is opened. When the high-temperature, high-pressure gaseous refrigerant enters the inside of the condenser 105... At this time, the cooling water supplied by the cooling tower can convert the high-temperature, high-pressure gaseous refrigerant into a high-pressure liquid refrigerant. Then, it is discharged from the outlet of the condenser 105 through another three-way pipe 112 and the corresponding first electric valve 111 (which is opened). The discharged high-pressure liquid refrigerant is first transported to the inside of the second connecting pipe 123, and then to the inside of the electric throttle valve 109. When the high-pressure liquid refrigerant passes through the throttling channel of the electric throttle valve 109, it is converted into a low-temperature, low-pressure mist refrigerant and transported to the inside of the evaporator 108. When the low-temperature, low-pressure mist refrigerant enters the inside of the evaporator 108, the corresponding water pump 116 is activated. The system 16, through the inlet pipe 118, water softener 119, and arc-shaped pipe 120, creates suction at the inlet end of filter 122. The suction-generated filter 122 then draws away the cold water from the cooling water pipes used for precision cooling loads, performs filtration and softening, and then first delivers it to the delivery pipe 117, and then to the evaporator 108. The evaporator 108 absorbs the heat from the delivered cold water, and the heat-absorbing low-temperature, low-pressure mist refrigerant is converted into low-pressure gaseous refrigerant. This low-pressure gaseous refrigerant is then delivered to the return pipe 106 for a new cycle. Similarly, the air conditioning load cooling uses a cooling channel and components matched with another inverter compressor 103. The cooling and temperature reduction operation operates on the same principle as described above. When the control cabinet 102 detects a decrease in air conditioning load through the temperature sensor 121 and the corresponding temperature threshold, the control cabinet 102 will control the speed of the variable frequency compressor 103 to decrease and the frequency of the water pump 116 to decrease. The same applies to precision loads, thus achieving energy saving. During heating, the outlet end of the water pipe 110 on the high-temperature circuit and the inlet end of the corresponding filter 122 are connected to the inlet and outlet ends of the building heating water pipe, respectively. Then, the valves of the two second electric valves 113 corresponding to the condenser 105 on the high-temperature circuit are opened, while the valves of the two corresponding first electric valves 111 are closed. Then, the variable frequency compressor 103 on the corresponding high-temperature circuit is started.At this time, the high-temperature, high-pressure refrigerant discharged from the outlet of the variable frequency compressor 103 is transported to the interior of the evaporator 108 through the corresponding open valve 113, the corresponding connecting pipe 114, the corresponding second connecting pipe 123, and the corresponding electric throttle valve 109. Then, the corresponding water pump 116 is started to circulate the chilled water, thus ensuring the building's heating needs are met through heat exchange.

[0035] Example 2: According to Figures 1-9As shown, the chiller unit mechanism 1 includes a main mounting frame 101. A control cabinet 102 is mounted on the front of the main mounting frame 101 near the top. A purification mechanism 5 is installed on the main mounting frame 101. The purification mechanism 5 includes two panels 501, two side panels 504, and a treatment box 509. A refrigerant sensor 508 is installed inside each threaded hole on each side panel 504. Multiple partitions 510 are fixed inside the top recess of the treatment box 509. A box cover 511 is installed on the top of the treatment box 509. A dual-shaft motor 512, a fan body 513, and an electromagnet 515 are also installed on the inner surface of the through hole on the cover. A connecting plate 514 is installed on the auxiliary shaft of the dual-shaft motor 512. An electromagnetic clutch 517 is installed on the surface of the connecting plate 514. The auxiliary shaft of the combiner 517 is fitted with a screw rod 516. A stop block 518 is movably inserted through the surface of the treatment box 509. Multiple adsorption layers 521 are arranged inside the groove at the top of the treatment box 509. Each adsorption layer 521 is topped with a perforated cover 522. A filter 523 is fixed at each air inlet of each perforated cover 522. Multiple electric push rods 524 are mounted on the top of the box cover 511. A stop rod 525 is installed at the telescopic end of each electric push rod 524. A manifold 526 connects the multiple air inlets on each perforated cover 522. A control valve 527 is connected to the air inlet of each manifold 526. A sealing ring 530 is installed inside the central hole at the bottom of each perforated cover 522. Two panels 501 and two side plates 5 04 are respectively installed on the four sides of the main mounting frame 101. Each through hole at the bottom of the main mounting frame 101 is fixed with a base plate 507. A top cover 506 is installed on the top of the main mounting frame 101. The processing box 509 is located inside the top cover 506. The panel 501, side plate 504, base plate 507 and top cover 506 are used to close the six sides of the main mounting frame 101. A perforated plate 502 is fixed inside the elongated hole of one of the panels 501. A first sealing ring 503 is provided inside the round hole of each panel 501 and the round hole of each perforated plate 502. A second sealing ring 505 is provided inside the round hole of each side plate 504. The processing box 509 is installed on the main mounting frame 101. The top of each partition 510 is connected to the box cover 51. The bottom of the two shaft motor 512 is in contact with the input shaft of the fan body 513 via a coupling. The screw rod 516 is threaded into the threaded groove on the stop block 518. Each square block at the front end of the stop block 518 is located inside a square hole on one of the panels 501. The exhaust end and the inlet end of the fan body 513 are respectively connected to an exhaust pipe 519 and an inlet pipe 520. One end of the inlet pipe 520 is fixedly inserted through the bottom of the inner wall of the top groove of the treatment box 509. The inlet pipe 520 is provided with multiple sets of air inlets, and each set of air inlets corresponds to an adsorption layer 521. Multiple adsorption layers 521 and multiple partitions 510 are arranged in an alternating manner. Each perforated cover 522 is installed between the treatment box 509 and the partition 510.The telescopic end of each electric push rod 524 is movably fitted into each circular hole on the cover 511. The blocking end of the stop rod 525 is used to block the air inlet on the air inlet pipe 520. The air inlet end of each control valve 527 is connected to a bend pipe 529. The air inlet end of each bend pipe 529 movably passes through the bottom of the cover 511. A diverter pipe 528 connects the air inlets of multiple bend pipes 529. The top end of each stop rod 525 is movably fitted into the inside of each sealing ring 530.

[0036] In this embodiment, when the control cabinet 102 detects a refrigerant leak in the chiller unit through the refrigerant sensor 508 and concentration threshold, the control cabinet 102 will shut off the electromagnet 515. Then, through the electromagnetic clutch 517, the dual-shaft motor 512, and the screw rod 516, the stop block 518 will be reset to its original position, blocking all the square holes on one of the panels 501. Next, the control cabinet 102 will activate one of the electric push rods 524. This activated electric push rod 524 will move the stop lever 525 upwards, releasing the blockage of the corresponding set of air inlets on the air inlet pipe 520. When the stop lever 525 moves to its maximum position... At this time, the control cabinet 102 will pause the electric push rod 524, and then open the corresponding valve on the corresponding control valve 527. When the control valve 527 is open, the control cabinet 102 will start the dual-shaft motor 512. The started dual-shaft motor 512 will drive the input shaft of the fan body 513 to rotate, causing the internal fan blades to rotate, that is, to give the air intake end of the fan body 513 suction. At this time, the fan body 513, which has obtained suction, will, in cooperation with the air inlet exposed on the air intake pipe 520, the manifold 526, the open control valve 527, the corresponding bend pipe 529 and the diverter pipe 528, draw air from the two side plates 50. 4. The gaseous refrigerant (which will vaporize upon leakage) in the sealed space composed of two panels 501, top cover 506, main mounting bracket 101, and multiple base plates 507 is drawn away. The drawn-away gaseous refrigerant is first transported to the inside of the bend 529, then sequentially to the inside of the control valve 527 (which opens the valve) and the manifold 526. Next, it enters the adsorption layer 521 through the air inlet with the perforated cover 522 and the filter 523 at the inlet. When the air mixed with gaseous refrigerant comes into contact with the corresponding adsorption layer 521, the gaseous refrigerant in the air is absorbed by the adsorption layer 521. After the refrigerant is adsorbed and removed, the treated air will enter the interior of the intake pipe 520 through a set of uncontrolled air inlets. Then, through the cooperation of the fan body 513 and the exhaust pipe 519, it will be transported back to the sealed space for a new cycle. If a large amount of refrigerant is leaked, the adsorption layer 521 can be switched in turn by the cooperation of the control valve 527 and the electric push rod 524 to ensure that all the leaked refrigerant is adsorbed and removed. This avoids the problems caused by the leaked refrigerant, such as global warming, soil and water pollution, injury to workers, and increased risk of safety accidents.

[0037] The overall effect and working principle of the mechanism are as follows: Before use, place the high and low temperature bidirectional air conditioning energy-saving chiller unit in the place where it is needed, then place two cooling towers around it, and connect each cooling tower and the corresponding condenser 105 with water pipes. After the cooling towers and condensers 105 are connected, first connect the control cabinet 102 to the power supply equipment, and then connect the inlet and outlet of the chilled water pipe for cooling the precision load to the outlet of one of the outlet pipes 110 and the inlet of one of the filters 122 respectively (used in the low temperature circuit). At the same time, connect the inlet and outlet of the chilled water pipe for cooling (or heating) the air conditioning load to the outlet of another outlet pipe 110 and the inlet of another filter 122 respectively (used in the high temperature circuit).

[0038] Simultaneously, the dual-axis motor 512 and electromagnetic clutch 517 are started via control cabinet 102. At this time, the auxiliary shaft of the started dual-axis motor 512 will drive the connecting plate 514 to rotate. The rotating connecting plate 514 will drive the electromagnetic clutch 517 to engage, driving the screw rod 516 to rotate. At the same time, the rotating screw rod 516 will drive the stop block 518 to move horizontally, allowing the front square block of the stop block 518 to leave through the square hole of one of the panels 501. When the stop block 518 moves to the point where it cannot move, the control cabinet 102 will pause the dual-axis motor 512 and close the electromagnetic clutch 517. Then, the electromagnet 515 will be started. At this time, the started electromagnet 515 will magnetically fix the moved stop block 518.

[0039] Refrigeration: In use, first set the speed of the two variable frequency compressors 103, the opening degree of the two electric throttle valves 109, the concentration threshold, and the temperature threshold on the control cabinet 102. At the same time, open the two first electric valves 111 on one of the condensers 105, and then start the variable frequency compressor 103. At this time, the started variable frequency compressor 103 will draw in the low-pressure gaseous refrigerant delivered back from the return pipe 106. The drawn-in low-pressure gaseous refrigerant will first be converted into high-temperature and high-pressure gaseous refrigerant, and then delivered to the first connection through one of the three-way pipes 112 and the corresponding first electric valve 111 that is opened. Inside pipe 115, when high-temperature, high-pressure gaseous refrigerant enters the condenser 105, the cooling water supplied from the cooling tower converts the gaseous refrigerant into high-pressure liquid refrigerant. This liquid refrigerant then exits through another three-way pipe 112 and the corresponding first electric valve 111 (which opens the valve) from the outlet of the condenser 105. The discharged high-pressure liquid refrigerant is then first transported to the second connecting pipe 123, and then to the electric throttle valve 109. When the high-pressure liquid refrigerant passes through the throttling channel of the electric throttle valve 109, it transforms into low-temperature liquid refrigerant. The refrigerant is compressed into a mist and delivered to the interior of the evaporator 108. When the low-temperature, low-pressure mist refrigerant enters the evaporator 108, the corresponding water pump 116 is activated. The activated water pump 116, through the inlet pipe 118, water softener 119, and arc-shaped pipe 120, creates suction at the inlet end of the filter 122. The filter 122, with the suction, then draws away the cold water from the cooling water pipes that are designed to cool precision loads. After filtration and softening, the water is first delivered to the interior of the delivery pipe 117 and then to the interior of the evaporator 108. That is, the evaporator 108 absorbs the heat from the delivered cold water. After the refrigerant absorbs heat, the low-temperature, low-pressure mist-like refrigerant will be converted into a low-pressure gaseous refrigerant. Then, the low-pressure gaseous refrigerant will be transported to the inside of the return pipe 106 for a new cycle. Similarly, the cooling of the air conditioning load is carried out by using another variable frequency compressor 103 with matching cooling channels and components. The principle is the same as above. When the control cabinet 102 detects that the air conditioning load has decreased through the temperature sensor 121 and the corresponding temperature threshold, the control cabinet 102 will control the speed of the variable frequency compressor 103 to decrease and the frequency of the water pump 116 to decrease. The same applies to precision loads, thus achieving the purpose of energy saving.

[0040] Heating (applied to building heating): In use, connect the outlet end of the water pipe 110 on the high-temperature circuit and the inlet end of the corresponding filter 122 to the inlet and outlet ends of the water pipe for building heating, respectively. Then, open the valves of the two second electric valves 113 corresponding to the condenser 105 on the high-temperature circuit, and at the same time close the valves of the two first electric valves 111. Then, start the variable frequency compressor 103 on the corresponding high-temperature circuit. At this time, the high-temperature and high-pressure refrigerant discharged from the outlet of the variable frequency compressor 103 will be transported to the interior of the evaporator 108 through the corresponding open valves of the second electric valve 113, the corresponding connecting pipe 114, the corresponding second connecting pipe 123 and the corresponding electric throttle valve 109. Then, start the corresponding water pump 116 to circulate the cold water. That is, the building heating needs are guaranteed through the heat exchange principle.

[0041] When control cabinet 102 detects a refrigerant leak in the chiller unit through the refrigerant sensor 508 and concentration threshold, it will shut off electromagnet 515. Then, through the electromagnetic clutch 517, dual-shaft motor 512, and screw rod 516, it will reset stop 518 to its original position, blocking all square holes on one of the panels 501. Next, control cabinet 102 will activate one of the electric push rods 524. This activated electric push rod 524 will move stop lever 525 upwards, releasing the blockage of the corresponding set of air inlets on the air inlet pipe 520. When the stop lever 525 is moved to its maximum position, the control cabinet 102 will pause the electric push lever 524 and then open the corresponding valve on the control valve 527. When the control valve 527 is open, the control cabinet 102 will start the dual-shaft motor 512. The started dual-shaft motor 512 will drive the input shaft of the fan body 513 to rotate, causing the internal fan blades to rotate, thus creating suction at the air intake end of the fan body 513. At this time, the fan body 513 with suction will be exposed at the air intake port on the air intake pipe 520, the manifold 526, and the control valve that has opened. 527. With the cooperation of the corresponding bend 529 and the diverter 528, the gaseous refrigerant (which will vaporize upon leakage) in the sealed space composed of two side plates 504, two panels 501, a top cover 506, a main mounting bracket 101, and multiple base plates 507 is drawn away. The drawn-away gaseous refrigerant is first transported to the inside of the bend 529, then sequentially to the inside of the control valve 527 (which opens the valve) and the inside of the manifold 526. Next, it enters the adsorption layer 5 through the air inlet with the perforated cover 522 and the filter 523 at the air inlet. Inside 21, when air mixed with gaseous refrigerant comes into contact with the corresponding adsorption layer 521, the gaseous refrigerant in the air will be adsorbed and removed by the adsorption layer 521. After the air has been processed, it will enter the interior of the intake pipe 520 through a set of air inlets that have been de-controlled. Then, through the cooperation of the fan body 513 and the exhaust pipe 519, it will be transported back to the sealed space for a new cycle. If there is a large amount of refrigerant leakage, the adsorption layer 521 can be switched in turn by the cooperation of the control valve 527 and the electric push rod 524.

[0042] Among them, the two variable frequency compressors 103, the two condensers 105 and the two evaporators 108 operate in low temperature circuit and high temperature circuit modes respectively, the refrigerant sensor 508 is an infrared absorption sensor, and the adsorption layer 521 is composed of a mixture of molecular sieve particles and activated carbon particles.

[0043] Among them, condenser 105, evaporator 108, water softener 119 and filter 122 are all existing technologies, and their models can be selected according to actual conditions. They will not be explained in detail here.
