What you want to ask is what is the reason for the high temperature in the water chamber of Mitsubishi's 2.5MW water cooling system? The reason is that the cooling water temperature is too high, the condensation effect is weak, the refrigerant is too charged, and the condenser is scaled or blocked. The details are as follows:
1. The cooling water temperature is too high and the condensation effect is weak. The rated operating condition of the cooling water required by the chiller is 30-35℃. High water temperature and poor heat dissipation will inevitably lead to high condensing pressure. This phenomenon often occurs during high temperature seasons.
2. Refrigerant overload. This situation usually occurs after maintenance and is manifested by high suction and exhaust pressure, a prebalancing pressure and high compressor operating current.
3. The condenser is limescale or blocked. Condensed water usually uses tap water, which tends to scale when the temperature is above 30°C. Additionally, because the cooling tower is open and directly exposed to the air, dust and foreign matter can easily enter the cooling water system, causing condensation. the condenser becomes dirty and blocked, and the heat exchange area is small, low efficiency, and also affects the water flow. The symptoms are that the pressure difference and temperature difference between the inlet and outlet water of the unit become larger, the upper and lower temperatures of the condenser are very high when touched by hand and the copper liquid outlet pipe of the condenser is hot to hot. touch.
Reasons and groundutions of establishment failure:
1. Check whether the main seal ring is worn, and replace it in time if it is worn.
2. Check if the water pressure in the stop plate is sufficient and if the small holes related to the water distribution mechanism are blocked. If the pressure is not enough, add water. after their blocking.
3. Check whether the plastic plug is blocking the drain hole. If it is blocked, clean it in time to solve the problem.
