Abstract
The utility model discloses a secondary refrigerant calorimeter, which comprises an upright barrel and a horizontal barrel horizontally connected with the bottom of the vertical barrel, a cooler is arranged in the vertical barrel, and a heating element is arranged in the horizontal barrel. The secondary refrigerant calorimeter has the advantages that: because the secondary refrigerant calorimeter adopts an inverted T-shaped design, the size of the device is effectively reduced, the space occupied by the secondary refrigerant calorimeter is saved, and the construction and usage of a lab are facilitated; on the other hand, the reduction of the size leads to the decrease of the amount of filled secondary refrigerant, and thereby the secondary refrigerant is prevented from leaking out in a great amount to harm the environment.
Description
Technical field
The utility model relates to chiller plant, relates in particular to the second refrigeration agent calorimetric device that is used for compressor formula refrigeration.
Background technique
The second refrigeration agent calorimetric device is a kind of core component that is widely used on the compressor test unit.
The second conventional refrigeration agent calorimetric device is generally airtight straight-tube shape structure.Because the size of heating element causes the diameter of cylindrical shell also bigger more greatly.Such structure need be used the second a large amount of refrigerant chargings.The calorimeter instrument volume is big simultaneously, makes that taking up room of entire equipment is big.
R123 is second refrigeration agent of using always, and filled in a large number and leakage can cause ozonosphere infringement and greenhouse gases effect, and a large amount of simultaneously filled second refrigeration agents are unfavorable for the construction and the use of test room.
The model utility content
The purpose of the utility model provides a kind of second refrigeration agent calorimetric device.
According to an aspect of the utility model, the second refrigeration agent calorimetric device is provided, comprise vertical cylindrical shell and with vertical cylindrical shell bottom transverse tube connected horizontally, vertically barrel is provided with cooling unit, transverse tube inside is provided with heating element.This second refrigeration agent calorimetric device is designed to inverted T shape, has reduced the volume of equipment, has reduced the charging amount of second refrigeration agent, has prevented to destroy environment because of a large amount of leakages of second refrigeration agent.
In some embodiments, vertically can be provided with visor on the cylindrical shell, can be observed the inner working condition of calorimeter instrument, more help control calorimeter instrument through visor.
In some embodiments, the cooling unit bottom can be provided with supporting frame, is used for fixing the support cooling unit, prevents that cooling unit from falling.
In some embodiments, cooling unit can be a cooling coil, and the cooling unit coil-like structure has increased the area of contact with gas second refrigeration agent, further improves the speed of gas phase and liquid phase conversion, improves the working efficiency of calorimeter instrument.
In some embodiments, heating element is the electric heating tube that axially inserts transverse tube, and electric heating tube is easy to operate, and the efficiency of heating surface is high.
Description of drawings
Fig. 1 is the structural representation of the second refrigeration agent calorimetric device of the utility model one mode of execution.
Fig. 2 is the principle schematic of cooling coil in the second refrigeration agent calorimetric device shown in Figure 1.
Fig. 3 is the plan view of cooling coil shown in Figure 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 has schematically shown the second refrigeration agent calorimetric device according to a kind of mode of execution of the utility model.As shown in the figure, this second refrigeration agent calorimetric device comprise vertical cylindrical shell 1 and with vertical cylindrical shell bottom transverse tube 2 connected horizontally.Vertically cylindrical shell 1 inside is provided with cooling unit, and cooling unit can be that cooling coil 3 or other have the cooling unit of same function.The coil-like structure of cooling coil 3 has increased the area of contact of itself and gas phase second refrigeration agent, can improve the transfer speed of liquid phase with gas phase, improves the working efficiency of calorimeter instrument.The bottom of cooling coil 3 is provided with supporting frame 5, is used for fixing and supports cooling unit.Vertically cylindrical shell is provided with visor 6, and the operator can understand the inner working condition of calorimeter instrument through visor 6.Be provided with heating element in the transverse tube, heating element can be axially to insert the inner electric heating tube 4 of transverse tube or other are applicable to the equipment of barrel heating.When second refrigerant flow of the cooling coil 3 of flowing through increased, the gasification of second refrigeration agent needed more heat, the supply that improves the second refrigeration agent heat in the cylindrical shell through the length that increases electric heating tube 4 usually.In use, when needing to increase electric heating tube 4 length, through transforming transverse tube 2 to adapt to the length of electric heating tube 4.Because it is cylindrical shell is a level, relatively easy during transformation.Heating pipe has increased, and the cylindrical shell volume changes less relatively, can reduce filling of second refrigeration agent.
During this second refrigeration agent calorimetric device work, second refrigeration agent that the machine that is compressed is discharged through a throttling arrangement, flows into cooling coil 3 through after the cooling liquid then.Liberated heat when liquid phase second refrigeration agent in the cooling coil 3 absorbs in the second refrigeration agent calorimetric device gas phase second condensation of refrigerant, second refrigeration agent that is gasificated into gas phase flows out, as shown in Figures 2 and 3.
Filled a certain amount of second refrigeration agent in advance in the second refrigeration agent calorimetric device, second refrigeration agent is liquid and gas two phase states in cylindrical shell.Second refrigeration agent of liquid phase is positioned at the bottom, and complete submergence bottom electrical heating pipe 4.Second refrigeration agent of gas phase is positioned at the top.Cooling coil 3 is among second refrigeration agent of gas phase.After gas phase second refrigeration agent runs into cooling coil 3, emit heat to cooling coil 3, and be condensed into liquid.Second refrigeration agent that liberated heat is cooled in the coil pipe 3 siphons away.Second refrigeration agent of liquid phase can flash to gaseous state after heating through electric heating tube 4.When second refrigeration agent from electric heating tube 4 heat absorption with form transient equiliblium to cooling coil 3 heat releases after, the calorimeter instrument internal pressure remains unchanged.Can measure the heat absorption of cooling coil 3 through the electric power of measuring input electric heating tube 4 like this from calorimeter instrument.And calculate the flow of compressor second refrigeration agent.
The advantage of the utility model is, the design of the employing inverted T shape of the second refrigeration agent calorimetric device has reduced the volume of equipment effectively, practices thrift its shared space.On the other hand, compare with the second refrigeration agent calorimetric device of routine, the reducing of volume descends second refrigerant charge, reduced the injury of second leakage of refrigerant to environment.
The foregoing description is merely a kind of in the utility model plurality of embodiments; It is not qualification to the utility model design; Under the prerequisite that does not break away from the utility model design philosophy; Various modification and improvement that engineers and technicians in related domain make the technological scheme of the utility model all should fall into the protection domain of the utility model.
