Today we  Water Cooled Chiller Manufacturer  manufacturers come to summarize The principle of condenser refrigeration. 1. The evaporative condenser combines the condensation process of the  water-cooled condenser  and the cooling tower with the water cooling process.  It uses cooling water to spread the film outside the heat exchanger into a film. Indirectly snoring with the atmosphere of forced activity, the material being cooled transfers heat to the water film, the water film produces unsaturated evaporation and stops the heat exchange and notification with the atmosphere, and the heat is taken away by the atmosphere. It stopped two improvements to the traditional cooling method: First, subtract the notification process of cooling water from the condenser to the cooling tower, indirectly completing the repeated use of water, and saving the pump power consumption; The second is to change the single-phase cooling fluid to cool the material with sensible heat temperature ris

The compressor discharge pressure reflects the condensing pressure, the normal value should be 1.4~1. 6MPa, and the protection value is set to 2.0MPa. If the long-term pressure is too high, it will lead to excessive operating current of the compressor, easy to burn the motor, and easily cause damage to the valve port of the compressor exhaust port. So what are the reasons for the high temperature failure of the chiller? Let's take a look at the coldest bacteria! First, the cooling water temperature is high, and the condensation effect is poor. The rated working condition of the cooling water required by the chiller is 30~35°C, the water temperature is high, and the heat dissipation is bad, which will inevitably lead to high condensing pressure. This phenomenon often occurs in the high temperature season. The cause of high water temperature may be: cooling tower failure, such as the fan is not open or even reversed, the water distributor does not turn, the cooling water tempe

If a company wants to use a chiller, it must first purchase and install a chiller. In the process of installing the chiller, it will encounter certain troubles. As is well known, because the weight of the refrigerator is relatively heavy, the installation process is also more difficult. When installing the refrigerant, the enterprise must first consider the lifting problem. It should be known that some medium and large refrigerators cannot be manpowered. For unloading and moving, equipment such as lifting machines must be used. In addition to considering hoisting, the selection and refurbishment of the installation and load-bearing area of the chiller are also very important. For the refrigerator to choose to install the load-bearing ground, it is necessary to consider the space independent, no debris around, heat dissipation and ventilation conditions, avoiding the sun and rain, the environment is not too humid, and the load-bearing ground is easy to be refurbished. The chill

The arrival of the hot summer days has affected the refrigeration performance of the refrigeration unit to some extent. In order to ensure the normal operation of the chiller in the summer, the air-cooled chiller should be communicated with customers and friends when it is used in the summer when the ambient temperature is relatively bad. Specific precautions and maintenance methods are as follows: 1. In order not to affect the cooling effect of the chiller, to ensure the normal operation of the laser equipment. Please put the chiller in a clean, ventilated place with good heat dissipation (it is recommended to put it outdoors and cover the sunshade roof. There is no large heat source in the space within 2M of the equipment). 2. please clean the condenser regularly, it is best to use a gas of not less than 0.8Mpa (usually with nitrogen) or a soft brush to clean the dust on the heat sink of the condenser (floating with the fins to prevent the fins from blowing) Pour) to avoid
