Description

Technical Field

[0001] The invention relates to the technical field of temperature regulating systems, and specifically provides an air supply device and a temperature regulating system for an air suspension bearing. Background Art

[0002] Air suspension compressors have become one of the mainstream development directions of centrifugal compressors due to their high efficiency, energy saving, and oil-free characteristics. Air suspension bearings are installed in air suspension compressors. When air suspension compressors are running, air needs to be supplied to the air suspension bearings.

[0003] The prior art air supply system usually provides an air supply tank for the air suspension compressor. Specifically, for a temperature control system using an air suspension compressor, firstly, part of the refrigerant in the condenser of the temperature control system is pumped into the air supply tank through a refrigerant pump, and then the liquid refrigerant in the air supply tank is heated by an electric heater to gasify the refrigerant and generate a stable pressure, and finally the gaseous refrigerant is transported to the air suspension bearing through a pipeline, thereby realizing the air supply of the bearing, see Figure 1 .

[0004] However, this method of heating the liquid refrigerant with an electric heater requires continuous power supply to the electric heater. However, the efficiency of the electric heater is always less than 1, which will consume a lot of energy and fail to achieve the effect of energy saving.

[0005] Therefore, there is an urgent need in the art for an air supply device and a temperature regulation system for an air suspension bearing to solve the above problems. Summary of the invention

[0006] The present invention aims to solve the above technical problem, that is, to solve the problem of excessive energy consumption when an electric heater heats liquid refrigerant.

[0007] In a first aspect, the present invention provides an air supply device for an air suspension bearing, the air supply device comprising:

[0008] A refrigerant tank connected to the air suspension bearing, the refrigerant tank being used to transport gaseous refrigerant to the air suspension bearing;

[0009] The heat pump assembly comprises a first condenser arranged in the refrigerant tank, wherein the first condenser can heat the refrigerant in the refrigerant tank into a gaseous state.

[0010] In a specific embodiment of the above-mentioned air supply device, the refrigerant tank is connected to the air suspension bearing through an air supply pipeline, so that the refrigerant tank can transport gaseous refrigerant to the air suspension bearing through the air supply pipeline.

[0011] In a specific embodiment of the above-mentioned air supply device, a control valve is provided on the air supply pipeline, and the control valve can control the air pressure of the gaseous refrigerant delivered to the air suspension bearing.

[0012] In a specific embodiment of the above-mentioned air supply device, the air supply device further includes:

[0013] an electric heater, which is disposed in the refrigerant tank and can heat the refrigerant in the refrigerant tank into a gaseous state when the electric heater is started;

[0014] A temperature detector is disposed in the refrigerant tank, and the temperature detector can obtain the temperature in the refrigerant tank;

[0015] A control module, the electric heater and the temperature detector are both electrically connected to the control module, and the control module can control the on / off state of the electric heater according to the temperature in the refrigerant tank.

[0016] In a second aspect, the present invention provides a temperature control system, which includes a second compressor and the above-mentioned air supply device, wherein an air suspension bearing is provided in the second compressor, and the refrigerant tank is connected to the air suspension bearing.

[0017] In a specific embodiment of the above temperature control system, the temperature control system further includes a second condenser, a second throttling device and a second evaporator, and the second compressor, the second condenser, the second throttling device and the second evaporator are sequentially connected to form a loop.

[0018] In a specific embodiment of the above temperature control system, the heat pump assembly further includes a first evaporator, a first compressor and a first throttling device, and the first condenser, the first throttling device, the first evaporator and the first compressor are sequentially connected to form a loop.

[0019] In a specific embodiment of the above temperature regulation system, the heat pump assembly further includes a first compressor and a first throttling device, and the first condenser, the first throttling device, the second evaporator and the first compressor are sequentially connected to form a loop.

[0020] In a specific embodiment of the above-mentioned temperature control system, the air supply device also includes a refrigerant pump, the inlet of the refrigerant pump is connected to the second condenser, and the outlet is connected to the refrigerant tank. The refrigerant pump can drive part of the refrigerant in the second condenser into the refrigerant tank.

[0021] In a specific implementation of the temperature control system, the air suspension bearing is connected to the second condenser so that the gaseous refrigerant at the air suspension bearing can enter the second condenser.

[0022] When the above technical solution is adopted, the first condenser of the heat pump assembly of the present invention releases heat in the refrigerant tank, heats the liquid refrigerant in the refrigerant tank, heats the liquid refrigerant to a gas state, and the gaseous refrigerant supplies air to the air suspension bearing. The heating efficiency of this heat pump assembly is much higher than the heating efficiency of the electric heater in the prior art. Specifically, the heating efficiency of the heat pump assembly is generally greater than 3, while the heating efficiency of the electric heater is only 0.9 to 1. Therefore, this arrangement can effectively reduce the energy consumption of heating the refrigerant.

[0023] Furthermore, the heat pump assembly and the temperature adjustment assembly share an evaporator, and this arrangement can save the cost of the temperature adjustment system. And the cold absorbed by the first condenser in the refrigerant tank can be released through the first evaporator. When the first evaporator is used for refrigeration, the cold of the liquid refrigerant can be used for refrigeration, thereby effectively utilizing the cold in the heat pump system.

[0024] Furthermore, when the temperature detector obtains that the external temperature of the first evaporator has not reached the preset temperature, it means that the heat pump component cannot provide sufficient heat to heat the liquid refrigerant. The control module can turn on the electric heater to assist in heating the liquid refrigerant in the refrigerant tank so that the air supply component can stably supply air to the air suspension bearing.

[0040] In order to solve the problem of excessive energy consumption when heating liquid refrigerant with an electric heater, this embodiment discloses a temperature control system, which is mainly used for heating or cooling, specifically an air conditioner, a refrigerator or other equipment.

[0041] The temperature regulation system includes a temperature regulation component, an air supply component and a heat pump component. The temperature regulation component is used for cooling or heating. The temperature regulation component includes a second compressor 401, and an air suspension bearing is arranged in the second compressor 401. The air supply component is used to provide a gaseous refrigerant to the air suspension bearing so that the air suspension bearing can maintain a suspended state. The heat pump component is used to heat the liquid refrigerant in the air supply component into a gaseous state so that the air supply component can stably supply air to the air suspension bearing.

[0042] The temperature adjustment system is described in detail below through two embodiments.

[0043] Embodiment 1

[0044] Reference Figure 2 The temperature regulating component is the main part of the temperature regulating system, which is used to realize the refrigeration function or heating function of the temperature regulating system. The temperature regulating component includes a second evaporator 404, a second compressor 401, a second condenser 402 and a second throttling device 403 which are sequentially connected in a cycle to form a refrigeration circuit. The second compressor 401 inhales the gaseous refrigerant from the second evaporator 404, compresses the gaseous refrigerant into a high-pressure and high-temperature gas, and drives the high-pressure and high-temperature gaseous refrigerant into the second condenser 402; the high-pressure and high-temperature gaseous refrigerant releases heat outward at the second condenser 402, so that the gaseous refrigerant condenses into liquid; the liquid refrigerant enters the second evaporator 404 through the second throttling device 403, and the second throttling device 403 can reduce the pressure of the liquid refrigerant, so that the liquid refrigerant becomes a low-pressure and low-temperature gas; the low-pressure and low-temperature gaseous refrigerant absorbs external heat in the second evaporator 404, and then enters the second compressor 401 again for circulation. The specific structure and working principle of the refrigeration cycle are the same as the refrigeration cycle or heating cycle in the prior art, and its specific structure and working principle are not repeated here. Those skilled in the art will appreciate that the temperature regulating component, refrigeration circuit or temperature regulating system herein does not limit the function of the temperature regulating component to refrigeration only. The refrigeration cycle can absorb heat for cooling through the second evaporator 404 , and can also release heat for heating through the second condenser 402 .

[0045] The second compressor 401 is an air suspension compressor. Specifically, an air suspension bearing is provided in the second compressor 401, and the number of the air suspension bearings is at least two. The air suspension compressor needs to be supplied with air when in operation.

[0046] The air supply assembly includes a device for supplying air to the air suspension bearing. The air supply assembly includes a refrigerant pump 102 and a refrigerant tank 101. The inlet of the refrigerant pump 102 is connected to the second condenser 402, and the outlet is connected to the refrigerant tank 101. The refrigerant pump 102 can drive part of the refrigerant in the second condenser 402 into the refrigerant tank 101. The refrigerant tank 101 can accommodate refrigerant, and the refrigerant tank 101 is connected to the air suspension bearing. The refrigerant entering the refrigerant tank 101 includes at least part of liquid refrigerant, so it is necessary to heat the liquid refrigerant into a gaseous state, and then transport the gaseous refrigerant to the air suspension bearing for air supply.

[0047] Specifically, the refrigerant tank 101 is connected to the air suspension bearing through an air supply pipeline. In the present embodiment, the air supply pipeline includes a main air supply pipeline and a plurality of branches, one end of the main air supply pipeline is connected to the refrigerant tank 101, and the other end is connected to a plurality of branches, and the branches are connected to the air suspension bearings one by one, so that the gaseous refrigerant in the refrigerant tank 101 can supply air to the plurality of air suspension bearings through the main air supply pipeline and the plurality of branches. Furthermore, a control valve is provided on the main air supply pipeline, and the control valve can control the air pressure of the gaseous refrigerant delivered to the air suspension bearing, so that the pressure of the gaseous refrigerant delivered to the air suspension bearing is stable. The control valve is specifically a pressure stabilizing valve, and the pressure stabilizing valve has the function of stabilizing air pressure. The structure of the pressure stabilizing valve is the same as that of the pressure stabilizing valve in the prior art, and its specific structure will not be repeated here.

[0048] Regarding the air supply pipeline, it should be noted that although the air supply pipeline in this embodiment includes a main air supply pipeline and multiple branches, this setting method is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other settings in other embodiments, for example: the refrigerant tank 101 may also supply air to multiple air suspension bearings through multiple air supply pipelines, the air supply pipelines are connected to the air suspension bearings one by one, and a control valve is provided on each air supply pipeline. This does not deviate from the basic principle of the present invention, and therefore falls within the protection scope of the present invention.

[0049] It should be noted that, regarding the control valve, although the control valve in the present embodiment is a pressure regulating valve, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, for example: the control valve may also include a shut-off valve, which can close or open the gas supply line. When the air pressure in the refrigerant tank 101 reaches a preset threshold, the shut-off valve is opened to ensure that the gas pressure provided by the gas supply system is not too low. This does not deviate from the basic principle of the present invention, and therefore falls within the scope of protection of the present invention.

[0050] In addition, the air suspension bearing is connected to the second condenser 402, so that the gaseous refrigerant at the air suspension bearing can enter the refrigeration cycle again, thereby realizing the recycling of the refrigerant. In addition, the refrigerant pump 102, the refrigerant tank 101, the air suspension bearing and the second condenser 402 form an air supply circuit.

[0051] The heat pump assembly includes a first compressor 203, a first condenser 201, a first throttling device 204 and a first evaporator 202 which are sequentially connected to form a heat pump circuit. The first compressor 203 can drive the refrigerant in the first evaporator 202 to enter the first condenser 201, so that the low-temperature and low-pressure gaseous refrigerant in the first evaporator 202 enters the first compressor 203, and the first compressor 203 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and drives it into the first condenser 201. The first condenser 201 is arranged in the refrigerant tank 101. The high-temperature and high-pressure gaseous refrigerant releases heat in the first condenser 201 to heat the liquid refrigerant in the refrigerant tank 101 into a gaseous state. The gaseous refrigerant forms a liquid refrigerant after releasing heat in the first condenser 201. The liquid refrigerant in the first condenser 201 enters the first throttling device 204, and the first throttling device 204 converts the liquid refrigerant into a low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant enters the first evaporator 202, so that the refrigerant continues to flow in the above-mentioned heat pump circuit.

[0052] The working principle of the temperature control system is as follows: when the temperature control system is in operation, the second compressor 401, the refrigerant pump 102 and the first compressor 203 are all turned on. The second compressor 401 drives the refrigerant to flow in the refrigeration circuit composed of the second compressor 401, the second condenser 402, the second throttling device 403 and the second evaporator 404, so that the second condenser 402 releases heat to the outside and the second evaporator 404 absorbs heat to the outside. The refrigerant pump 102 drives part of the refrigerant to flow in the air supply circuit composed of the second condenser 402, the refrigerant pump 102, the refrigerant tank 101 and the air suspension bearing. The first compressor 203 drives the refrigerant to flow in the heat pump circuit composed of the first evaporator 202, the first compressor 203, the first condenser 201 and the first throttling device 204. The first condenser 201 releases heat in the refrigerant tank 101, heats the liquid refrigerant in the refrigerant tank 101, and heats the liquid refrigerant to a gas state. The gaseous refrigerant supplies air to the air suspension bearing. The gaseous refrigerant after air supply enters the second condenser 402 and enters the refrigeration circuit or the air supply circuit again. The refrigerant that releases superheat in the first condenser 201 enters the first evaporator 202 through the first throttling device 204. The refrigerant absorbs external heat at the first evaporator 202, and is then driven by the first compressor 203 to continue flowing in the heat pump circuit.

[0053] The first compressor 203 of the heat pump assembly provides power to drive the refrigerant to circulate in the heat pump circuit, so that the refrigerant absorbs external heat at the first evaporator 202, and releases heat at the first condenser 201 to heat the liquid refrigerant in the refrigerant tank 101. The heating efficiency of this heat pump system is much higher than the heating efficiency of the electric heater 301 in the prior art. The heating efficiency refers to the ratio between the useful heat generated during the heating process and the energy consumed. Specifically, the heating efficiency of the heat pump system is usually greater than 3, while the heating efficiency of the electric heater 301 is only 0.9 to 1. Therefore, this setting can effectively reduce the energy consumption of heating the refrigerant.

[0054] Embodiment 2

[0055] Reference Figure 3 The temperature regulating component is the main part of the temperature regulating system, which is used to realize the refrigeration function or heating function of the temperature regulating system. The temperature regulating component includes a second evaporator 404, a second compressor 401, a second condenser 402 and a second throttling device 403 which are sequentially connected in a cycle to form a refrigeration circuit. The second compressor 401 inhales the gaseous refrigerant from the second evaporator 404, compresses the gaseous refrigerant into a high-pressure and high-temperature gas, and drives the high-pressure and high-temperature gaseous refrigerant into the second condenser 402; the high-pressure and high-temperature gaseous refrigerant releases heat outward at the second condenser 402, so that the gaseous refrigerant condenses into liquid; the liquid refrigerant enters the second evaporator 404 through the second throttling device 403, and the second throttling device 403 can reduce the pressure of the liquid refrigerant, so that the liquid refrigerant becomes a low-pressure and low-temperature gas; the low-pressure and low-temperature gaseous refrigerant absorbs external heat in the second evaporator 404, and then enters the second compressor 401 again for circulation. The specific structure and working principle of the refrigeration cycle are the same as the refrigeration cycle or heating cycle in the prior art, and its specific structure and working principle are not repeated here. Those skilled in the art will appreciate that the temperature regulating component, refrigeration circuit or temperature regulating system herein does not limit the function of the temperature regulating component to refrigeration only. The refrigeration cycle can absorb heat for cooling through the second evaporator 404 , and can also release heat for heating through the second condenser 402 .

[0056] The second compressor 401 is an air suspension compressor. Specifically, an air suspension bearing is provided in the second compressor 401, and the number of the air suspension bearings is at least two. The air suspension compressor needs to be supplied with air when in operation.

[0057] The air supply assembly includes a device for supplying air to the air suspension bearing. The air supply assembly includes a device for supplying air to the air suspension bearing. The air supply assembly includes a refrigerant pump 102 and a refrigerant tank 101. The inlet of the refrigerant pump 102 is connected to the second condenser 402, and the outlet is connected to the refrigerant tank 101. The refrigerant pump 102 can drive part of the refrigerant in the second condenser 402 into the refrigerant tank 101. The refrigerant tank 101 can accommodate refrigerant, and the refrigerant tank 101 is connected to the air suspension bearing. The refrigerant entering the refrigerant tank 101 includes at least part of liquid refrigerant, so it is necessary to heat the liquid refrigerant into a gaseous state, and then transport the gaseous refrigerant to the air suspension bearing for air supply.

[0058] Specifically, the refrigerant tank 101 is connected to the air suspension bearing through an air supply pipeline. In the present embodiment, the air supply pipeline includes a main air supply pipeline and a plurality of branches, one end of the main air supply pipeline is connected to the refrigerant tank 101, and the other end is connected to a plurality of branches, and the branches are connected to the air suspension bearings one by one, so that the gaseous refrigerant in the refrigerant tank 101 can supply air to the plurality of air suspension bearings through the main air supply pipeline and the plurality of branches. Furthermore, a control valve is provided on the main air supply pipeline, and the control valve can control the air pressure of the gaseous refrigerant delivered to the air suspension bearing, so that the pressure of the gaseous refrigerant delivered to the air suspension bearing is stable. The control valve is specifically a pressure stabilizing valve, and the pressure stabilizing valve has the function of stabilizing air pressure. The structure of the pressure stabilizing valve is the same as that of the pressure stabilizing valve in the prior art, and its specific structure will not be repeated here.

[0059] Regarding the air supply pipeline, it should be noted that although the air supply pipeline in this embodiment includes a main air supply pipeline and multiple branches, this setting method is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other settings in other embodiments, for example: the refrigerant tank 101 may also supply air to multiple air suspension bearings through multiple air supply pipelines, the air supply pipelines are connected to the air suspension bearings one by one, and a control valve is provided on each air supply pipeline. This does not deviate from the basic principle of the present invention, and therefore falls within the protection scope of the present invention.

[0060] It should be noted that, regarding the control valve, although the control valve in the present embodiment is a pressure regulating valve, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, for example: the control valve may also include a shut-off valve, which can close or open the gas supply line. When the air pressure in the refrigerant tank 101 reaches a preset threshold, the shut-off valve is opened to ensure that the gas pressure provided by the gas supply system is not too low. This does not deviate from the basic principle of the present invention, and therefore falls within the scope of protection of the present invention.

[0061] In addition, the air suspension bearing is connected to the second condenser 402, so that the gaseous refrigerant at the air suspension bearing can enter the refrigeration cycle again, thereby realizing the recycling of the refrigerant. In addition, the refrigerant pump 102, the refrigerant tank 101, the air suspension bearing and the second condenser 402 form an air supply circuit.

[0062] The heat pump assembly includes a first compressor 203, a first condenser 201 and a first throttling device 204. The first compressor 203, the first condenser 201, the first throttling device 204 and the second evaporator 404 are sequentially connected to form a heat pump circuit. The first compressor 203 can drive part of the refrigerant in the second evaporator 404 to enter the first condenser 201, so that the low-temperature and low-pressure gaseous refrigerant in the second evaporator 404 enters the first compressor 203, and the first compressor 203 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and drives it into the first condenser 201. The first condenser 201 is arranged in the refrigerant tank 101. The high-temperature and high-pressure gaseous refrigerant releases heat in the first condenser 201 to heat the liquid refrigerant in the refrigerant tank 101 into a gaseous state. The gaseous refrigerant forms a liquid refrigerant after releasing heat in the first condenser 201. The liquid refrigerant in the first condenser 201 enters the first throttling device 204, and the first throttling device 204 converts the liquid refrigerant into a low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant enters the second evaporator 404, so that the refrigerant enters the refrigeration circuit or enters the heat pump circuit again.

[0063] The temperature control system of this embodiment is basically the same as the temperature control system of embodiment 1, except that the refrigeration circuit and the heat pump circuit share an evaporator. Specifically, the first compressor 203, the first condenser 201, the first throttling device 204 and the second evaporator 404 are connected in sequence to form a heat pump circuit; the second compressor 401, the second condenser 402, the second throttling device 403 and the second evaporator 404 are connected in sequence to form a refrigeration circuit. This arrangement enables the temperature control system to use only one evaporator, thereby saving the cost of the system. In addition, the cold absorbed by the first condenser 201 in the refrigerant tank 101 can be released through the first evaporator 202. When the first evaporator 202 is used for refrigeration, the coldness of the liquid refrigerant can be used for refrigeration, thereby effectively utilizing the coldness in the heat pump system.

[0064] The description of the temperature adjustment system is completed through the above two embodiments.

[0065] In addition, since the heat pump component heats the refrigerant by absorbing external heat through the first evaporator 202 or the second evaporator 404, when the external heat is insufficient or the external temperature is low, the heat pump component cannot obtain enough heat to heat the refrigerant. This will make the air supply component unable to stably supply air to the air suspension bearing. In order to solve this problem, the temperature control system also includes an auxiliary heating component.

[0066] Reference Figure 3 and Figure 4 The auxiliary heating component includes an electric heater 301, a temperature detector 302 and a control module. The electric heater 301 is also arranged in the refrigerant tank 101. When the electric heater 301 is started, the liquid refrigerant in the refrigerant tank 101 can be heated to a gas state. The temperature detector 302 is arranged in the refrigerant tank 101, and the temperature detector 302 is used to obtain the temperature in the refrigerant tank 101. The electric heater 301 and the temperature detector 302 are both electrically connected to the control module, and the control module can control the on and off state of the electric heater 301 according to the temperature in the refrigerant tank 101 obtained by the temperature detector 302.

[0067] The working principle of the auxiliary heating component is as follows: the temperature detector 302 obtains the temperature in the refrigerant tank 101. The control module determines whether the temperature in the refrigerant tank 101 reaches the preset temperature. When the temperature in the refrigerant tank 101 does not reach the preset temperature, it means that the heat pump component cannot provide enough heat to heat the liquid refrigerant, and the electric heater 301 is turned on to assist in heating the liquid refrigerant in the refrigerant tank 101. If the temperature in the refrigerant tank 101 reaches the preset temperature, it means that the heat pump component can provide enough heat to heat the liquid refrigerant, and the electric heater 301 is turned off, and heating is performed only by the heat pump component.

[0068] The control module is configured to execute the above-mentioned control method of the auxiliary heating component. The control module can be configured only to execute the control method and not to execute other operation controls of the temperature control system. Other operation controls can be equipped with other control modules. It can also be configured to execute other operation controls of the temperature control system in addition to executing the control method, that is, the control module is a comprehensive execution module, that is, it executes various programs in the operation of the temperature control system.

[0069] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
