Description

Technical Field

[0001] The utility model belongs to the technical field of condenser equipment, and specifically relates to an automatic monitoring device for the refrigeration effect of a condenser. Background Art

[0002] The condenser is a refrigeration element used in cold storage and other places. It is usually used with an evaporator, a compressor and a throttle valve. It achieves refrigeration by absorbing the heat of the heat transfer medium through the refrigerant and quickly dissipating it to the outside. The refrigeration effect is restricted by the performance of the condenser, and the condenser needs to be monitored in real time.

[0003] A central control machine is installed inside the cold storage, which regulates the flow of the compressor and throttle valve on one side and connects two temperature sensors on the other side. The two temperature sensors are inserted into the inlet and outlet of the condenser respectively to monitor the difference between the inlet and outlet temperatures in real time. The larger the difference, the better the cooling effect of the condenser. If the difference is less than a certain range, it means that the condenser needs to be repaired.

[0004] Temperature sensors are inserted at the inlet and outlet of the condenser to automatically monitor the difference between the inlet and outlet temperatures. Heat accumulation on the condenser will cause the temperature to rise. Once the temperature is higher than 55°, it is easy for the internal water to form scale, which makes the scale adhere to the temperature sensor and difficult to clean, which hinders the detection end of the temperature sensor. For this reason, we propose an automatic monitoring device for the condenser refrigeration effect. Utility Model Content

[0005] The utility model aims to provide an automatic monitoring device for the refrigeration effect of a condenser, separate the water flow and the temperature sensor, reduce the scale attached to the detection end of the temperature sensor, and reduce the obstruction of the temperature sensor detection end by the scale.

[0006] The technical solutions adopted in this utility are as follows:

[0007] The automatic monitoring device for condenser refrigeration effect comprises a tubular condenser and two tees, one port of each of the two tees is respectively connected to the inlet and outlet of the tubular condenser, the middle ports of the two tees are respectively provided with a sealing plug, the two sealing plugs are both annular in structure, temperature sensors are axially inserted inside the two sealing plugs, the detection ends of the two temperature sensors extend into the middle port of the tees and the detection ends are both sleeved with a silicone pad, the two silicone pads are interference fit with the middle port of the tees, and during monitoring, the two tees are used to connect the water inlet pipe and the water outlet pipe respectively, and the heat of the inlet and the outlet is respectively transmitted along the adjacent silicone pads. The pad is transmitted to the temperature sensor, and the two temperature sensors detect two temperature signals respectively. The control mainboard monitors the two temperature signals and the difference between the two temperature signals in real time, and sends them to the computer in the duty room through the signal transmitter. At the same time, a silicone pad is used to separate the water flow and the temperature sensor. The surface of the silicone pad is smooth and not easy to stick, which can reduce the scale attached to the detection end of the temperature sensor and reduce the obstruction of the temperature sensor detection end by the scale. In addition, the closing plug, temperature sensor and silicone pad are all fixed at the middle port of the tee, and do not extend to the channel formed by the other two ports of the tee, which can avoid obstruction to the water inlet and outlet of the tubular condenser.

[0008] A light-curing adhesive strip is fixed to the outside of the two silicone pads. The two light-curing adhesive strips are both annular in shape. The outsides of the two light-curing adhesive strips are fixedly connected to the middle port of the tee. The annular light-curing adhesive strip is used to bond the outsides of adjacent silicone pads to the middle port of the tee. While fixing the silicone pad, the gap between the silicone pad and the middle port of the tee may be closed to improve the sealing performance.

[0009] An annular groove is also provided on the outside of the two silicone pads, which respectively wrap the two light-curing adhesive strips. The annular groove is utilized to increase the axial contact area between the silicone pad and the light-curing adhesive strip, and to limit the position, thereby preventing the silicone pad from being deformed and slipping relative to the hardened light-curing adhesive strip when squeezed by water flow.

[0010] A sealing ring is also provided inside the two sealing plugs, and the two sealing rings are respectively sleeved on the outside of the two temperature sensors. The sealing ring is used to seal the gap between the temperature sensor and the sealing plug, which can improve the sealing inside the sealing plug and reduce the occurrence of water seepage inside the sealing plug.

[0011] The ends of the two closing plugs that are away from each other are both threaded with locking screws until they are pressed against the temperature sensor, and the temperature sensor can be locked by friction. Conversely, the locking screws can be reversed and separated from the temperature sensor along the threads to release the locking effect.

[0012] The outer edges of the two middle ports of the tee pieces are threadedly installed with threaded sleeves, and the inner edges of the two threaded sleeves extend toward the outside of the adjacent closing plugs. After the closing plug is inserted into the middle port of the tee piece, the threaded sleeve is assembled to the outer edge of the middle port of the tee piece along the thread until it is tightly against the closing plug to lock the closing plug. Otherwise, the threaded sleeve is unscrewed to facilitate the disassembly of the closing plug and the temperature sensor.

[0013] The technical effects achieved by this utility model are:

[0014] The practical automatic monitoring device for condenser refrigeration effect uses two tees to respectively connect the water inlet pipe and the water outlet pipe during monitoring, and the heat of the inlet and the outlet is respectively transferred to the temperature sensor along the adjacent silicone pads. The two temperature sensors respectively detect two temperature signals, and the control mainboard monitors the two temperature signals and the difference between the two temperature signals in real time, and sends them to the computer in the duty room through the signal transmitter. At the same time, a silicone pad is used to separate the water flow and the temperature sensor. The surface of the silicone pad is smooth and not easy to adhere, which can reduce the scale attached to the detection end of the temperature sensor and reduce the obstruction of the temperature sensor detection end by the scale. In addition, the closing plug, the temperature sensor and the silicone pad are all fixed at the middle port of the tee and do not extend to the channel formed by the other two ports of the tee, which can avoid obstruction to the water inlet and outlet of the tubular condenser.

It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-5 As shown, the automatic monitoring device for condenser refrigeration effect comprises a tubular condenser 1, a Chinese utility model with reference announcement number CN210441483U, an intelligent condenser for an industrial refrigeration unit, a signal transmitter, a control mainboard and a network adapter are arranged on the outside of the tubular condenser 1, and the signal transmitter and the network adapter are both connected to the control mainboard by signal, and also comprises two tee pieces 2, one port of the two tee pieces 2 is respectively connected to the inlet and outlet of the tubular condenser 1, the middle ports of the two tee pieces 2 are both inserted with closing plugs 3, the two closing plugs 3 are both annular in structure, temperature sensors 4 are axially inserted inside the two closing plugs 3, the two temperature sensors 4 are both electrically connected to the control mainboard, the detection ends of the two temperature sensors 4 extend into the middle port of the tee piece 2 and the detection ends are both sleeved with silicone pads 5, the two silicone pads 5 are both interference fit with the middle port of the tee piece 2, water is pumped into the tubular condenser 1 from the inlet and leaves the tubular condenser 1 from the outlet, and a circulating pump is used in the pipeline and the pipe The refrigerant is pumped between the tube condensers 1 for circulation to take away the heat inside the tube condenser 1 and dissipate heat and cool the water flow. The heat accumulation on the tube condenser 1 may cause scale to form on the water flow. During monitoring, two tee pieces 2 are used to connect the water inlet pipe and the water outlet pipe respectively. The heat of the inlet and the outlet is transferred to the temperature sensor 4 along the adjacent silicone pads 5 respectively. The two temperature sensors 4 detect two temperature signals respectively. The control mainboard monitors the two temperature signals and the difference between the two temperature signals in real time, and sends them to the computer in the duty room through the signal transmitter. At the same time, the silicone pad 5 is used to separate the water flow and the temperature sensor 4. The surface of the silicone pad 5 is smooth and not easy to adhere. It can reduce the scale attached to the detection end of the temperature sensor 4 and reduce the obstruction of the detection end of the temperature sensor 4 by the scale. In addition, the closing plug 3, the temperature sensor 4 and the silicone pad 5 are all fixed at the middle port of the tee piece 2, and do not extend to the channel formed by the other two ports of the tee piece 2, which can avoid obstruction to the water inlet and outlet of the tube condenser 1.

[0024] The network adapter can be equipped with a WIFI module, and selects a network cable or a WIFI signal to transmit data, and sends the two temperature signals and the difference between the two temperature signals to the computer in the duty room in real time. Among them, the temperature sensor 4 can be purchased from a thermistor on the market, which has a certain level of protection. Once water seepage occurs, it will not cause damage for a long time.

[0025] like Figure 2 and Figure 4As shown, a light-curing adhesive strip 6 is fixed to the outside of the two silicone pads 5. The two light-curing adhesive strips 6 are both annular in shape. The outside of the two light-curing adhesive strips 6 are fixedly connected to the middle port of the tee 2. The annular light-curing adhesive strips 6 are used to bond the outside of the adjacent silicone pads 5 to the middle port of the tee 2. While fixing the silicone pads 5, the gap between the silicone pads 5 and the middle port of the tee 2 may be closed to improve the sealing performance.

[0026] like Figure 2 and Figure 4 As shown, annular grooves 7 are further provided on the outer sides of the two silicone pads 5, and the two annular grooves 7 respectively wrap the two light-curing adhesive strips 6. The annular grooves 7 are utilized to increase the axial contact area between the silicone pad 5 and the light-curing adhesive strip 6, and to limit the position, thereby preventing the silicone pad 5 from being deformed and slipping relative to the hardened light-curing adhesive strip 6 when squeezed by water flow.

[0027] like Figure 2 and Figure 4 As shown, sealing rings 8 are further provided inside the two closing plugs 3. The two sealing rings 8 are respectively sleeved on the outside of the two temperature sensors 4. The sealing rings 8 are used to seal the gap between the temperature sensor 4 and the closing plugs 3, which can improve the sealing inside the closing plugs 3 and reduce the occurrence of water seepage inside the closing plugs 3.

[0028] like Figure 2 and Figure 3 As shown, the ends of the two closing plugs 3 that are away from each other are both threaded with locking screws 9. The locking screws 9 are rotated forward and enter the closing plugs 3 along the threads until they are pressed against the temperature sensor 4. The temperature sensor 4 can be locked by friction. Conversely, the locking screws 9 are reversed and detached from the temperature sensor 4 along the threads to release the locking effect.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the outer edges of the middle ports of the two tees 2 are threadedly installed with threaded sleeves 10, and the inner walls of the two threaded sleeves 10 are threadedly connected to the outer edges of the middle ports of the tee 2. The inner edges of the two threaded sleeves 10 extend toward the outsides of the adjacent closing plugs 3. After the closing plug 3 is inserted into the middle port of the tee 2, the threaded sleeves 10 are assembled to the outer edges of the middle ports of the tee 2 along the threads until they are tightly against the closing plug 3 to lock the closing plug 3. Otherwise, the threaded sleeves 10 are unscrewed to facilitate the disassembly of the closing plug 3 and the temperature sensor 4.

[0030] The working principle of the utility model is: during monitoring, two tees 2 are used to connect the water inlet pipe and the water outlet pipe respectively, and the heat of the inlet and the outlet is transferred to the temperature sensor 4 along the adjacent silicone pads 5 respectively. The two temperature sensors 4 detect two temperature signals respectively, and the control mainboard monitors the two temperature signals and the difference between the two temperature signals in real time, and sends them to the computer in the duty room through the signal transmitter.

[0031] At the same time, a silicone pad 5 is used to separate the water flow and the temperature sensor 4. The surface of the silicone pad 5 is smooth and not prone to adhesion, which can reduce the scale attached to the detection end of the temperature sensor 4 and reduce the obstruction of the detection end of the temperature sensor 4 by the scale. In addition, the closing plug 3, the temperature sensor 4 and the silicone pad 5 are all fixed at the middle port of the tee 2 and do not extend to the channel formed by the other two ports of the tee 2, which can avoid obstruction to the water inlet and outlet of the tubular condenser 1.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
