Oil separators are used on refrigeration systems where it’s difficult for the oil to return from the evaporator. These typically are field built-up systems, such as in supermarkets, and ultra-low temperature systems.

Oil separators are installed in the compressor/compressor discharge line. They’re usually a vertical container with the discharge gas connections at the top and an oil return port at the bottom. This return line may be piped directly to the suction line on single compressor units or on multiple compressor racks that would be piped to a holding tank called an oil reservoir. Some oil separators have a reservoir built into the bottom portion of the container with the upper portion being the separator.

From the reservoir, the oil is then returned to the compressors by use of a mechanical or electronic oil level control fastened to the compressor crankcase.

Oil separators use various modes of oil separation methods to remove the oil from the discharge gas as it leaves the compressor. These methods include reduction of velocity, impingement, centrifugal action, or coalescing elements. Oil separators vary in capacity and efficiency depending upon the mass flow that is being pumped through them and no oil separator is 100% efficient.

Evaporators & Its Types,

  EVAPORATORS The process of  evaporation  is used widely in the chemical and process industry, and for a variety of purposes. These include the concentration of solutions (often as a precursor to the crystallization of the solute), re-vaporization of liquefied gases, refrigeration applications (cooling or chilling), and generation of pure and mixed vapors for process applications. The term  evaporators  are usually reserved vapors for the first of these applications, namely the evaporation of the solvent from a solution in order to concentrate the solution. Evaporators may be classified into  falling film evaporators  (in which evaporation takes place from the film interface with no nucleate boiling at the wall),  nucleate boiling evaporators  (in which wall nucleate boiling occurs over part or all of the heat transfer surface),  flash evaporators and direct contact evaporators . Types of Evaporators:- Falling Film Evaporators: The fall...

HVAC Interview 35 Questions & Answers

  Question 1. What Is a Local Comfort Cooling System? Answer : They may be integrated, with heating, ventilation, and air conditioning provided by a single system, for example, air handling units connected to ductwork, or they may be a combination of separate systems, for example, mechanical ventilation but with radiators for heating and local comfort cooling units. Question 2. What Is a Centralised Air System? Answer : The most common central cooling system is a split system, which includes an outdoor cabinet containing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with your furnace. or air handler. The compressor pumps a chemical called refrigerant through the system. Question 3. What Is Constant Volume System? Answer : Constant Air Volume (CAV) is a type of heating, ventilating, and air-conditioning (HVAC) system. In a simple CAV system, the supply airflow rate is constant, but the supply air temperature is varied to meet the th...

  Refrigerant retrofit guide Guide for how and why to retrofit an HVAC system to a new environmentally friendly refrigerant In this refrigerant retrofit guide, we will be looking at how to retrofit a refrigeration system with the new, environmentally friendly, refrigerants that are coming into the market due to the changes to laws and regulations on the types of refrigerants that can be used. Why retrofit refrigerant Firstly the reason the laws and regulations are tightening on refrigerants is all due to the damaging effects the previous generations of refrigerants had on the environment. The first generations of refrigerants were found to have burnt a hole in the Ozone layer and the later types of refrigerants are being phased out due to their global warming potential. One of the downsides to retrofitting a system with a new refrigerant is that there will be a compromise on system performance and efficiency. The system was originally designed to handle another type of refrige...
