Industrial refrigeration and industrial processes utilize it, and it also forms a part of the HVAC system. Evaporative condensers reduce system condensing temperature, minimizing compressor horsepower and saving energy compared to a conventional air cooling system. It is a low-cost option and condenses refrigerant vapor in coils continually sprayed with water. Here we will cover features and related parameters for getting a good industrial evaporative condenser.
Factors to Consider When Selecting an Evaporative Condenser
- Choose the right industrial evaporative condensers that have good cooling features. The main thing to consider is energy efficiency since it has an effect on the operational costs.
- Find modules that have energy efficiency, like variable speed fans or high-efficiency filled material, for increased condenser performance and reduced energy use.
- Noise level is also a good factor, especially for an urban area where noise affects working people or violates local regulations.
- Advanced condenser made for noise reduction features and can be invaluable for a good operational environment.
- Also check the evaporative condenser footprint; where space is limited, units made for optimizing area use without affecting performance are important. In these conditions, working with good modules helps to get a good design.
Types of Evaporative Condensers
- There are two main types of evaporative condensers.
- Forced draft evaporative condensers
- Induced draft evaporative condensers
Forced Draft
- Forced draft evaporative condensers pull air in at the base, then condense and release in saturated conditions through an opening at the upper part of the cooling unit.
- This condenser type is a centrifugal fan-driven type or an axial type that is commonly used.
- The use of a forced draft condenser based on proper features of type and efficiency for getting cooling.
Axial Fan Design
- It is an important type of evaporative condenser that is used in industries. It is used on a larger scale in industry for fast cooling. This forced draft condenser type has some features such as.
- Fan design helps to work with a low horsepower motor.
- It has different capacity ranges for use in different industries.
- Easy-to-access mechanical component with low-cost maintenance
Centrifugal Fan
- Centrifugal fan used for cooling applications where sound is the main issue. These devices are noisier than an axial fan and the centrifugal fan condenser used for indoor locations. These evaporative condensers are used for halocarbon AC systems and work noiselessly.
Induced Draft
- Induced draft evaporative condenser operated with pulling air in chiller conditions through the condenser configured at its base. The collected air condensed and circulated to the cooling for the related process. The main features for this condenser are as follows.
- It reduces floor space.
- High efficiency
- Fewer components used than the forced draft model
Cooling Tower vs. Evaporative Condenser
- The main difference is that chiller configuration exists in different phases for getting good cooling effects.
- The chiller system that uses cooling tower heat transfer from the cooling process has two steps.
- The heat produced through the industrial process is first shifted to circulating chiller fluid through the condenser unit before atmospheric heat releases at the cooling tower. The combination of chillers and cooling towers at the same time needed two-level heat exchangers.
- While chillers with evaporative condensers get the same features with a single heat rejection process that uses evaporation of heated water from the external surface of the coolant tubing
Function of the evaporative condenser
- The evaporative condenser is used for removing extra heat from the cooling system when heat is not used for other work. The extra heat was removed through evaporating water. The evaporative condenser comes with a cabinet with a water-sprayed condenser, and it comes with one or more fans.
Function of a condenser in an industrial system
- The main use of an industrial condenser is to remove heat from the process. This is important for the refrigeration system and provides power to plants where heat is effectively handled.
Where is an evaporative condenser used?
- It is used for industrial refrigeration, HVAC systems, and industrial processes.
What is the difference between a condenser and an evaporator?
- The evaporator coil exists inside the home and absorbs heat from the indoor air, cools it, and the refrigerant evaporates in the coil. The condenser coils exist on the external side of the home and release heat absorbed from the indoor through the condensing refrigerant again in liquid.
Evaporative condenser vs. cooling tower
- The main difference is that the primary coolant of the cooling system is cooled.
- Both have the same physical working; thermal exchange in cooling towers occurs in the filling, and in a condenser, it occurs in the tubular bundle where the fluid or water circulates for heat loss.
- The other difference is how much time is taken to get cooling effects.
- Cooling towers have two steps for removing heat, and heat is transferred to the circulating chiller fluid using the condenser unit and then released to the atmosphere.
- The chiller that comes with evaporative condensers comes with one step for the heat rejection process.
Evaporative condenser advantages and disadvantages
- Evaporative condensers are more expensive than other coolants like dry coolers, as they are used here in high outdoor temperature environments.
- The energy efficiency of this module is also high, and it uses less fan horsepower for running than an air-cooled design, so it reduces energy expenses and helps to save costs.’
- It can be easy to install, and maintenance is also simple.
- Regulations in different places also affect the size of the cooling system, and evaporative condensers are used for larger cooling systems. There is a need to check the regulation of the place and ensure that there are no limitations.
