With the arrival of summer and the increasing temperature, more and more customers urgently need to replace the evaporative condenser to meet the requirements of on-site process operation. In order to accelerate production progress, our workers are also working overtime to catch up with production progress.  Evaporative condensers for peak cooling systems are being shipped in batches to the customer site.

The evaporative condensers use both air and water as condensing mediums to condense the hot vapour refrigerant and convert it into liquid refrigerant. In short, it is a type of indirect cooling, where the heat of vapour refrigerant is taken by water and water is cooled by air. These condensers perform the combined functions of a water-cooled condenser and a cooling tower. Water is pumped from a water tank to a spray header (with nozzles) and it is sprayed through nozzles over the condenser coils, through which, the hot vapour refrigerant received from the compressor is flowing. Heat is transferred from the vapour refrigerant through the condensing tube walls to the outside water, which is passing over the outside surface of the tubes. Due to heat rejected by hot vapour refrigerant to the cold water, it becomes liquid refrigerant. At the same time, the air is drawn from the bottom side of the condenser by a fan(located at the top). The air is discharged out from the top of the condenser. The air causes the water droplets to adhere to the surface of the condenser coils to evaporate by absorbing the heat from the remaining water, which is required for their evaporation. The heat absorbed by these water droplets is called the latent heat of evaporation or vapourization. Due to heat rejection, the remaining water gets cooled. This cod water collected in the water tank at the bottom is again re-circulated into the circuit. At the same time, air also absorbs some part of the heat from water droplets to evaporate them. Thus, the air becomes hot and is discharged from the top to the atmosphere. In order to make up for the deficiency of water caused by the evaporated water, make-up water is supplied to the water tank. A float valve in the water tank controls the make-up supply. Water eliminator plates are provided above the spray header to prevent particles of water from the escaping discharged air.
