What is the difference between a condenser and a heat exchanger? What is the difference between an air compressor and a vacuum pump?

I’m a beginner. On the flowchart, the same device is sometimes referred to as a condenser and sometimes as a heat exchanger. What’s the difference between these two? There are also air compressors and vacuum pumps
It is recommended to read more books and operating procedures related to the industry, as this can be very helpful in improving one’s professional skills. In simple terms, a heat exchanger is a place or device where two substances exchange heat with each other； Among them, a condenser generally refers to a device that uses circulating water to cool a certain medium; it is a type of heat exchanger.
A heat exchanger is a general term, while a cooler is a more specific designation. For liquefied gas, condensers, evaporators, etc., in a process, they can all be referred to as heat exchangers. In a device, in order to more precisely address temperature changes of a specific medium, evaporation, condensation, and liquefaction occur. Vacuum and compression are both pressures resulting from energy conversion. The terms used to denote pressure vary: absolute pressure, gauge pressure, and atmospheric pressure – all of these refer to pressure values. However, the reference points used are different, but absolute pressure values must be used for conversion in all cases. Just as 0°C in Celsius equals 273°K in absolute temperature. The recommended reference book is \"Principles of Chemical Engineering\". It is a required book for those working in the chemical industry.
