Description

Technical Field

[0001] The invention relates to a magnetic suspension type centrifugal heat pump unit, in particular to a magnetic suspension type centrifugal heat pump unit applied in the field of heat pumps. Background Art

[0002] The core of the magnetic levitation centrifugal heat pump unit is the magnetic levitation compressor. The magnetic levitation heat pump is an important equipment in modern air-conditioning and heating systems. It is based on the principles of thermodynamics and drives the refrigerant circulation through electric energy to achieve energy transfer and enhancement between low-temperature heat sources and high-temperature heat loads.

[0003] The centrifugal heat pump unit is mainly composed of the following parts: magnetic levitation centrifugal compressor, evaporator, condenser and expansion valve. Among them, the centrifugal compressor uses the centrifugal force generated by the rotation of the impeller to pressurize and heat the gaseous refrigerant, so that it can release heat to the environment at a higher pressure; the evaporator is responsible for absorbing heat from the low-temperature heat source, evaporating the refrigerant and lowering its temperature; then, the high-pressure and high-temperature refrigerant enters the condenser and transfers the heat to the space or water source that needs to be heated; finally, the refrigerant, which has been reduced in pressure, cooled and throttled by the expansion valve, enters the evaporator again, completing a complete heat pump cycle.

[0004] In order to solve the problem of cooling efficiency of centrifugal heat pump units, a certain heat pump unit in the market adopts a design of multiple condensers and has a certain market share.

[0005] Chinese invention patent CN118274475A discloses a cascade magnetic suspension heat pump system, including a shell and tube condenser, a magnetic suspension compressor, several groups of heat pump systems, several plate heat exchangers, and several condensers. Each heat pump system is connected in series with a plate heat exchanger, and the first inlet end of each plate heat exchanger is connected to a condenser. The first outlet ends of several plate heat exchangers are connected in parallel to the inlet end of the shell and tube condenser, and the outlet end of the shell and tube condenser is connected to the inlet end of the magnetic suspension compressor. The outlet end of the magnetic suspension compressor is connected in parallel with the inlet end of several condensers; and heat exchange pipes are connected in parallel on several condensers. The invention has the advantages of the system still running during defrosting, independent defrosting, fast defrosting speed, stable system operation, and no fluctuation in the circulation temperature of the refrigerant.

[0006] When the load of the existing heat pump suddenly changes significantly, the control system of the post-cooling fluid flow may not be able to respond accurately immediately. Due to the operating characteristics of the magnetic levitation heat pump itself and the complexity of the control system, there is a certain time difference between detecting the load change and completing the accurate adjustment of the post-cooling fluid flow. During this lag time, the heat pump unit may operate under non-optimal cooling conditions, which will affect the performance and service life of the magnetic levitation bearing. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when the load of the heat pump suddenly changes significantly, the control system of the post-cooling fluid flow rate may not be able to respond accurately immediately.

DETAILED DESCRIPTION

[0032] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-6 It is shown that a magnetic levitation centrifugal heat pump unit includes a condenser 1 and an evaporator 2. A compressor body 3 is installed on the condenser 1. A coolant pipe is connected between the compressor body 3 and the condenser 1 and the evaporator 2. The evaporator 2 includes a protective shell 21. A fluid input pipe 22 and a fluid output pipe 25 are installed at the upper and lower ends of the protective shell 21 respectively. A guide cover covering one end of the fluid input pipe 22 and the fluid output pipe 25 is fixedly connected to the side end of the protective shell 21. A partition is arranged between the fluid input pipe 22 and the fluid output pipe 25. A plurality of compensation pipes 23 are fixedly connected to the partition. Solenoid valves are installed at both ends of the compensation pipe 23. The two solenoid valves are respectively communicated with the guide cover and the fluid output pipe 25; guide holes are opened at both ends of the partition, and the upper and lower sides of the partition are communicated through the guide holes;

[0035] A coolant input pipe 24 communicating with the compressor body 3 is fixedly connected to the top of the protective shell 21. The coolant output by the compressor body 3 is input into the protective shell 21 through the coolant input pipe 24. The fluid output pipe 25 and the fluid input pipe 22 are both copper pipes and exchange heat with the coolant. Under low load conditions, fluid is stored in the compensation pipe 23 for a long time. On the one hand, the compensation pipe 23 serves as a backup fluid source. On the other hand, multiple compensation pipes 23 cooperate with the partition to isolate the fluid output pipe 25 from the fluid input pipe 22 up and down to avoid mutual influence between the fluid output pipe 25 and the fluid input pipe 22.

[0036] The evaporation tube 2 is fixedly connected with a main input pipe and a main output pipe, a flow control valve and a relief valve are installed on the main output pipe, the main input pipe is communicated with the fluid input pipe 22; the main output pipe is communicated with the fluid output pipe 25;

[0037] The input end of the compressor body 3 is fixedly connected with a strain tee pipe 4 matching the condenser pipe 1, and the side input end of the strain tee pipe 4 is fixedly connected with a compensation tank 5;

[0038] The strain tee pipe 4 includes a tee pipe shell 41, a valve pipe 42 is installed at one end of the tee pipe shell 41 close to the compensation tank 5, a movable valve block 43 is slidably connected in the valve pipe 42, a plug rod 45 slidably connected to the tee pipe shell 41 is installed at the top of the movable valve block 43, a permanent magnet is installed at the top of the plug rod 45, an active cavity is opened at the top of the tee pipe shell 41, an electromagnet 44 matching the permanent magnet is fixedly connected in the active cavity, and a self-resetting spring is connected between the plug rod 45 and the inner wall of the active cavity;

[0039] The compensation tank 5 includes a main tank body 51, in which a pressurizing plug 52 is slidably connected, a hydraulic adjustment mechanism 53 is connected between the main tank body 51 and the pressurizing plug 52, an electromagnetic clamp 6 is installed inside the main tank body 51, and a clamping groove matching the movable end of the electromagnetic clamp 6 is opened at the side end of the pressurizing plug 52.

[0040] The electromagnetic clamp 6 includes an electromagnetically driven movable clamp column, and a tension reset spring is connected between the movable end and the fixed end of the movable clamp column. The movable clamp column extends when the electromagnetic clamp 6 is powered on, and the movable clamp column contracts and resets after the electromagnetic clamp 6 is powered off; the fixed end of the movable clamp column is an electromagnet block, and the telescopic end of the movable clamp column is provided with a permanent magnet, and the tension reset spring is installed between the permanent magnet and the electromagnet block;

[0041] The hydraulic adjustment mechanism 53 includes a stepper motor, and the power output end of the stepper motor is fixedly connected to a rotating shaft 531. One end of the rotating shaft 531 located in the main tank body 51 is threadedly connected to a movable cylinder 532. A compression spring is connected between the movable cylinder 532 and the pressure plug 52. Pressure sensors are installed on both the pressure plug 52 and the plug rod 45.

[0042] When the hydraulic adjustment mechanism 53 is working, the stepper motor drives the rotating shaft 531 to rotate, thereby moving the movable cylinder 532, and then pressurizing the compression spring. When the device is working normally, the electromagnetic clamp 6 is energized, and the pressurizing plug 52 is limited by the electromagnetic clamp 6, so that the rotating shaft 531 rotates to adjust the pressurized state of the pressurizing plug 52. After the limit of the electromagnetic clamp 6 is released, the pressurizing plug 52 can pressurize the coolant in the main tank 51 under the action of the compression spring, so that the coolant in the main tank 51 is discharged;

[0043] The compensation tank 5 adjusts the pressure state of the pressurizing plug 52 according to the real-time load and the preset load to ensure that after the strain tee pipe 4 is triggered, the spare coolant in the compensation tank 5 can be quickly input into the compressor body 3;

[0044] In this solution, when the equipment load is greater than the set value, the electromagnet 44 and the electromagnetic clamp 6 are powered off to reset the movable valve block 43, thereby opening the side input end of the strain tee 4 and releasing the limit of the pressurizing plug 52. At this time, the coolant stored in the main tank 51 is pushed out and output to the strain tee 4 under the action of the pressurizing plug 52, thereby increasing the coolant flow output from the strain tee 4 to the compressor body 3, thereby timely adjusting the fluid output of the compressor body 3;

[0045] In the process of the compensation tank 5 outputting the coolant, according to the load conditions, a set number of compensation tubes 23 are selected to be opened, so that the evaporation tube 2 can output the fluid with the required flow rate and qualified temperature in time; so that the evaporation tube 2 can quickly adapt to the load change, and in the process of the compensation tube 23 outputting the fluid, the overall device completes the adjustment of the coolant and fluid flow rate;

[0046] When switching from low-load operation to high-load operation, during the process of adjusting the fluid flow rate, the compensation pipe 23 is used to provide a fluid output that meets the load requirements, and a sufficient amount of coolant is input to the compressor body 3 through the compensation tank 5; when switching from low-load operation to high-load operation, the situation that the heat exchange requirements of the compressor body 3 under high load cannot be met due to insufficient coolant flow is avoided, and the magnetic suspension bearing is ensured to exchange heat with sufficient coolant when the compressor body 3 is under high load;

[0047] During the time period when the pipeline flow rate is adjusted to the flow rate required for high load, sufficient coolant is input to the compressor body 3 through the compensation tank 5 to ensure that the flow rate and flow rate of the coolant input to the compressor body 3 meet the high-load working requirements during the flow rate adjustment period. At the same time, the compensation pipe 23 provides cooled fluid output, so that during the equipment adjustment process from low load to high load working conditions, the evaporator tube 2 can quickly output the required flow rate of fluid.

[0048] This solution is applicable to air source heat pumps and water source heat pumps, and is easily adapted to low heat demand scenarios.

[0049] Second implementation method:

[0050] Figure 5-7 As shown, it also includes a fluid control system, which includes a processor installed on the condenser tube 1, and the processor is connected to a control module, a monitoring module and an adaptive module;

[0051] The control module is used to control the switch and operating parameters of the specified equipment according to the instructions of the processor to control the flow direction and flow rate of the fluid; the control module adjusts the switch state of the actuators such as the solenoid valve, electromagnet, and stepper motor to control the flow direction and flow rate of the fluid; the processor receives the real-time data provided by the monitoring module, and according to these data and the preset control strategy, sends instructions to the actuators such as the solenoid valve and stepper motor through the control module;

[0052] The monitoring module is used to collect monitoring data of each key component in the unit and feed the monitoring data back to the processor. The monitoring data includes: equipment load, coolant flow rate, output fluid flow rate and liquid storage volume in the compensation tank 5; a current sensor matching the monitoring module is installed in the compressor body 3, and a pressure sensor, temperature sensor and flow sensor matching the monitoring module are installed in the evaporation tube 2 and the condensation tube 1;

[0053] The adaptive module is used to determine whether to trigger the compensation mode according to the data provided by the monitoring module. When the compensation mode is triggered, the operation of the designated equipment is automatically adjusted according to the preset program, so that the compensation tank 5 outputs the coolant to the compressor body 3, and the compensation tube 23 in the evaporation tube 2 is opened and outputs the fluid;

[0054] When the monitoring module detects that the equipment load is greater than the set threshold, the compensation mode is triggered, and the control module cuts off the power to the strain tee 4 and the electromagnetic clamp 6, so that the strain tee 4 is quickly opened, so that the fluid in the compensation tank 5 is output to the compressor body 3 through the strain tee 4, and according to the load conditions, a set number of compensation tubes 23 are opened to output the fluid;

[0055] This solution monitors the heat pump load during operation. When the heat pump load is greater than the set value, the strain tee pipe 4 is triggered to cut off the power supply. At this time, the valve pipe 42 in the strain tee pipe 4 is reset, and the compensation tank 5 at this time inputs the spare coolant in it into the compressor body 3, ensuring that the compressor body 3 can adapt to the cooling demand when the load increases rapidly;

[0056] When the compensation tank 5 outputs the standby coolant, the fluid output volume is detected. When the output fluid volume reaches the set flow rate, it is detected whether the evaporation tube 2 has completed the adjustment, that is, it is determined whether the output fluid flow rate of the evaporation tube 2 meets the requirements; when the low load is switched to the high load, the compensation tank 5 provides the compressor body 3 with a sufficient flow of coolant, and when the load increases, the coolant flow input to the compressor body 3 increases rapidly, which makes it easy to ensure that the compressor body 3 quickly adapts to the high load condition;

[0057] When the load is restored, the coolant can be input into the compensation tank 5 through the external pipeline, and the hydraulic adjustment mechanism 53 can be adjusted to restore the compensation tank 5 to its initial state and restore the compensation tank 5 to its liquid storage state, so that the subsequent compensation mode can continue to work.

[0058] In summary, this solution realizes real-time monitoring of the heat pump load and automatically adjusting the input amount of the coolant according to the load change, ensuring that the compressor body 3 can obtain appropriate cooling under different working conditions. When the load increases rapidly, the coolant is quickly output through the compensation tank to meet the cooling needs of the compressor body 3. The compensation pipe 23 can also assist the fluid output at the evaporation pipe 2, so that the fluid output that meets the temperature requirements is sufficient when the equipment is adjusted. When the load decreases, the system can replenish the coolant in the compensation tank 5 in time to ensure that it is in a standby state at any time and is ready for the next load increase. This solution not only improves the operating efficiency of the heat pump unit, but also extends the service life of the equipment, and has significant economic benefits and application value.

[0059] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
