Description

Technical Field

[0001] This application relates to the technical field of supporting devices for laboratory and industrial equipment, specifically to an integrated air source and cooling fluid circulation unit. Background Technology

[0002] In laboratory analytical instruments (such as atomic absorption spectrometers, plasma emission spectrometers, and mass spectrometers) and in industries such as semiconductors and medicine, many devices require the simultaneous use of air source systems and cooling fluid circulation systems. The air source system provides a stable supply of compressed or dry air to meet the operational requirements of the pneumatic components of the working equipment (external devices); the cooling fluid circulation system controls the temperature of critical components of the working equipment (such as optical elements and plasma torches), ensuring stable operation at a constant temperature.

[0003] Currently, air source heat pumps and cooling fluid circulation systems on the market are typically designed and supplied separately. When using these devices, customers face several challenges. First, they need to reserve installation locations for two independent main units in the laboratory. For example, in the application of atomic absorption spectrometers, the air source heat pump provides a stable gas supply for instrument operation, while the cooling fluid circulation system maintains the appropriate temperature for critical internal components to prevent overheating and performance degradation. This separate layout occupies significant laboratory space, failing to meet the laboratory's need for efficient space utilization, leading to wasted space and limiting the layout and expansion of other laboratory equipment. Second, because the two systems exist independently, customers need to perform separate operations such as powering on and setting parameters for both the air source heat pump and the cooling fluid circulation system, undoubtedly increasing the workload for operators. Third, the lack of integrated design between the separate air source heat pump and cooling fluid circulation systems makes installation, maintenance, and use inconvenient. Utility Model Content

[0004] Therefore, this application provides an integrated air source and cooling fluid circulation unit to solve the technical problems of low laboratory space utilization and increased workload for operators during equipment installation and use caused by the separate existence of air source equipment and cooling fluid circulation equipment in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An integrated air source and cooling fluid circulation unit includes: a housing, an embedded controller, and a refrigeration unit, a liquid circulation unit, and an air source unit integrated within the housing. The liquid circulation unit is connected to the refrigeration unit and the air source unit respectively, and the embedded controller is used to control the refrigeration unit, the liquid circulation unit, and the air source unit.

[0007] The refrigeration unit includes an evaporator, the liquid circulation unit includes a liquid tank containing liquid, and the air source unit includes a heat exchanger. The evaporator and the heat exchanger are respectively disposed in the liquid tank and are disposed below the liquid level.

[0008] Optionally, the refrigeration unit further includes: a refrigeration compressor, a condenser, a dryer filter, and a throttling device, wherein the outlet of the refrigeration compressor is connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the dryer filter, the outlet of the dryer filter is connected to the inlet of the throttling device, the outlet of the throttling device is connected to the inlet of the evaporator, and the outlet of the evaporator is connected to the inlet of the refrigeration compressor.

[0009] Optionally, the liquid circulation unit further includes a circulation pump and an outlet pipe and a return pipe connected to the liquid tank. The outlet pipe and the return pipe are used to connect with the external device to form a liquid circulation loop, and the circulation pump is connected in series on the outlet pipe.

[0010] Optionally, the air source unit further includes an air compressor, an air tank, and an air-water separator. The air outlet of the air compressor is connected to the air inlet of the heat exchanger, the air outlet of the heat exchanger is connected to the air inlet of the air tank, the air outlet of the air tank is connected to the air inlet of the air-water separator, and the air outlet of the air-water separator is connected to an external device through an air outlet pipe.

[0011] Optionally, the refrigeration unit further includes a fan for dissipating heat from the condenser.

[0012] Optionally, the refrigeration unit further includes a refrigerant charging port, which is located on the pipeline between the evaporator outlet and the inlet of the refrigeration compressor.

[0013] Alternatively, a level switch may be provided on the liquid tank for monitoring the liquid level.

[0014] Further optionally, the air source unit also includes a pressure regulating valve and a pressure gauge, the pressure regulating valve and the pressure gauge being disposed on the pipeline between the air storage tank and the air-water separator, the pressure gauge being disposed after the pressure regulating valve.

[0015] Alternatively, a drain valve is provided at the bottom of the gas storage tank, which is used to drain the liquid inside the gas storage tank.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] An integrated air source and cooling fluid circulating unit includes a housing, an embedded controller, and a refrigeration unit, a liquid circulation unit, and an air source unit integrated within the housing. The liquid circulation unit is connected to both the refrigeration unit and the air source unit. The embedded controller controls all three units. Firstly, because the refrigeration unit, liquid circulation unit, and air source unit are integrated and controlled uniformly by the embedded controller, users only need to install, power on, and set parameters for one unit during installation and operation, simultaneously achieving air supply and cooling fluid temperature control. This avoids the cumbersome process of installing and operating two separate main units, significantly reducing operator workload. By integrating the refrigeration unit, liquid circulation unit, and air source unit into the same housing, it completely changes the traditional model of separate configuration of air source and cooling water equipment. Secondly, by placing the evaporator and heat exchanger within the liquid tank below the liquid level, heat exchange between the refrigeration unit, liquid circulation unit, and air source unit is achieved. Specifically, the refrigeration unit can cool the liquid in the tank through the evaporator, ensuring that the liquid temperature is controlled within the required range for use by the liquid circulation unit; the heat exchanger of the air source unit can also use the liquid in the tank to cool the output air. This compact heat exchange design allows the equipment to not only meet the temperature requirements of the output air and liquid during operation, but also eliminates the need to reserve installation space for two separate sets of equipment, reducing the equipment size compared to traditional solutions, further minimizing the space occupied in the laboratory, and improving the utilization rate of laboratory space.

The fan 3 is located next to the condenser 2 and opposite to the ventilation grille on the casing, used to blow air onto the condenser 2 for heat dissipation.

[0026] The refrigeration compressor 1, condenser 2, dryer filter 4, throttling device 5, and evaporator 6 are connected by pipelines.

[0027] A refrigerant charging port 7 is installed on the pipeline between the outlet of the evaporator 6 and the inlet of the refrigeration compressor 1 to replenish refrigerant.

The outlet pipe a and return pipe b are connected to the liquid tank 8. The circulation pump 9 is connected in series to the outlet pipe a, which is connected to the liquid inlet of an external device. The return pipe b is connected to the liquid outlet of the external device, thus forming a closed-loop circulation circuit for the liquid. The external device is a device used in conjunction with an integrated air source and cooling liquid circulation unit (such as an atomic absorption spectrometer). The evaporator 6 is located inside the liquid tank 8 and is completely submerged below the liquid level in the tank, thereby cooling the liquid through the refrigeration unit.

[0029] In a preferred embodiment, a level switch 17 is disposed on the liquid tank 8 for monitoring the liquid level and feeding back the monitoring information to the embedded controller.

[0030] The air source unit includes an air compressor 10, a heat exchanger 11, an air tank 12, and an air-water separator 16.
