• About 80 to 93 % of the electrical energy used by a compressor get transformed to heat. The temperature in the compressor room must not exceed 35°C to ensure an optimally working compression process. Thus a cooling system for the compressor is needed. Many companies simply let this waste heat dissipate into the atmosphere.

• "Biomass - organic material of non-fossil origin, such as organic waste - can be converted into bioenergy through various processes (combustion, anaerobic digestion, gasification,etc.). , directly or through derivative products. Around 64% of the total primary energy production of renewable energy in the EU-28 in 2016 is generated in this way. Technologies for the production of heat and electricity from biomass are well developed in many applications. Biomass heating systems range from small stoves for households with capacities ranging from 5 kilowatts (kW) to 100 kW (often powered by wood and wooden pallets), to large boilers for farms, commercial buildings or in industry, which reach a capacity of 100 kW to 500 kW (powered by a variety of raw materials such as wood chips and miscanthus). Large heating systems for district heating or industrial use have a capacity of 1 MW to 500 MW and are able to use various biomass raw materials, including wood chips, straw and miscanthus. Biomass can also be converted into cogeneration plants that produce both electricity and heat (CHP) with a typical ratio of 1:2 to 1:3, with a possible overall efficiency of 70-90%. Cogeneration plants have substantially higher capital costs than thermal energy-only plants of the same scale, and on a smaller scale (less than 10 MW) the electrical efficiency of the plant is typically lower. It is therefore important to find a constant heat demand to ensure the economic profitability of the investment. "

• "Cooling systems are designed to meet a maximum cooling load that normally occurs for less than 5% per year. The most frequent case concerns loads that stand at 50% compared to the maximum design load with an ambient temperature 20 degrees lower than the design ones. For these reasons, a compressor regulation system should always be installed. For systems consisting of several compressors, the optimal solution could be to combine a fixed-speed compressor covering the base load with variable speed compressors for peak loads. "

• The evaporation temperature and condensation temperature define the COP of the chiller. Therefore, they have a great impact on the efficiency of the cooling system. However, these parameters are often poorly set and offer savings potential.
