  • H.Stars Group condensing units improve the food processing industry
    H.Stars Group condensing units improve the food processing industry
    Project Overview 1. This project is a cold storage project of a foreign-invested food company in Zhongshan, China. The project includes a 6T / secondary freezing warehouse (-35 ℃), a finished product warehouse, a raw material warehouse, a rolling room and a production workshop. 2. Equipment configuration description: The quick-freezing warehouse of this project adopts an H.Stars Group low-temperature single-compressor dual-stage condensing unit (the condensation equipment is equipped with an evaporative condenser), and the evaporator of the quick-freezing warehouse adopts a variable-pitch vertical cooler. Other cold storage uses a combination of one-to-one air-cooled condensing unit and ceiling-mounted chiller. Project advantages 1. The quick-freezing warehouse uses a single-compressor dual-stage condensing unit. The screw single-compressor dual-stage compression refrigeration cycle has a reduced pressure ratio per stage, less leakage, and less insulation loss; high volumetric efficiency and large cooling capacity; the intercooler is overcooled, which makes the cooling capacity Increased, improved refrigeration factor; rotor bearing with low stress and long service life; high thermal insulation efficiency, motor power saving, energy saving, easy to realize automatic control; 2. The heat recovery function of the condensing unit of the quick-freezing warehouse is provided to provide free hot water washing for the workshop;  3. By transforming the evaporative condenser storage tank into a frost water pool, the frost water and condensate water are mixed to realize the recovery of cold and heat energy, which not only improves the condensation effect of the quick-freezing condensing unit, but also guarantees several times. The temperature of frosting water will not be too low after circulation; 4. The water flushing system of this project recovers the frosting water for the evaporative condenser, which not only achieves the effect of saving water, but also solves the problems of cleanliness and temperature of the flushing water (the conventional water flushing system needs to be discharged regularly) Partly flush the frost water and add tap water) 5. Other cold storage condensation units and chillers use one corresponding method; the system is safe and reliable;  6. The evaporative condenser is used for the condensation equipment of the quick-freezing warehouse, which has large air volume and good heat dissipation effect.  7. The entire project adopts a centralized monitoring system, which is simple to operate, monitors the temperature of the cold storage at anytime and anywhere, and has a cold storage failure alarm function.

  • How does H.Stars Group produce a high quality air cooled chiller ?
    How does H.Stars Group produce a high quality air cooled chiller ?
    Since H.Stars Group has been established for more than 28 years so far, some of you might wonder how H.Stars produces a high quality air cooled chiller. Below is the detailed production process with strict quality control system and 100% testing before delivery. 1. Chiller Frame welding: clean the bracket and select the appropriate welding method according to the specifications of the welding materials and the technical requirements of the drawings. Chiller Bracket assembly: the bent compressor, filter and other brackets are assembled and welded according to the dimensions required by the drawing. 2.Refrigerant pipeline connection: For the vibration mode of the compressor, use a suitably shaped pipe to avoid resonance points near the power frequency; you can avoid resonance by adding weight. 3. Chiller Bracket assembly 4. Assembly of fin type condenser: the fin type condenser jointly produced by the subsidiary of H.Stars Group, according to customer requirements and engineer design. 5.Sheet metal: the electric control box shell on the H.Stars chiller is designed and manufactured independently, and the quality is under the control of the factory. 6.Layout of electrical components According to the electrical schematic diagram, the layout of the electrical components and the wire slot is reasonably discharged on the electrical base plate, and the hole position of the corresponding component and the installation hole position of the wire slot are marked with a pencil and drilled. The layout requires that the components should not be hindered by space during operation, and there should be no possibility of touching the charged body. 7.Electric control box and compressor wiring: The controller imports the latest version of the program according to the factory operation standards before installation, and sets and adjusts the corresponding parameters according to the model parameter comparison table and customer requirements. 8.Equipment testing station National standard testing station, the factory equipment must be tested, and only after passing the test can the goods be delivered to ensure reliable product quality. 9. Large equipment testing station Can test 800RT ~ 3000RT equipment, mainly detect centrifuge and large equipment, large equipment necessary facilities, it rare in the industry. 10.Pack insulation cotton Confirm customer requirements of the order chiller and the type of chiller, and clarify the position and standard of the chiller to be wrapped with thermal insulation cotton. The chiller pump and related waterway system parts are not wrapped with thermal insulation cotton before the test machine. It is necessary to check whether there is a leakage through the test machine process. The test machine can be wrapped with no thermal insulation leakage. 11.Outside spray The main parts of H.Stars chiller are evaporator and condenser. The products are produced independently. According to customer requirements, the appearance uses different colors ...
