Cooling and heating in one system reduce the need for fossil fuels and save energy

Combining cooling, freezing, air-con and heating in one system reduces the need for fossil fuels and saves energy. The excess heat from the cooling process can be used for comfort heating, hot tap water, process heating or even sold to the grid. This also eliminates waste and thereby higher energy efficiency is obtained. The sustainable solution is based on the natural refrigerant CO2 (R-744).

Description

Cooling and heating are vital for our modern society. Sustainable cooling and heating are vital for reaching the UN Sustainable Development Goals. We need cooling to keep food and medicine fresh and to store data, and heating for comfort or process heating. An Advansor climate solution combines cooling, freezing, air-con and heating in one system, using only the natural refrigerant CO2 (R-744).

-With a climate solution, the excess heat from the cooling process is used for comfort heating, hot tap water, process heating or even for selling to the grid. Thereby no fossil fuels like gas are needed.
-The solution gives increased energy efficiency by reduced waste, same investment costs, lower energy consumption and thereby lower total cost of ownership.
-For instance, climate solutions within supermarkets, discount stores, and hypermarkets provide cooling for the cabinets, freezing for the rooms, air-con for the store, heating for the store and hot tap water.
-For a hotel, a climate solution can provide cooling and freezing for the kitchen, air-con for the hotel rooms and fitness centre, and heating for the swimming pool, hotel rooms and showers.
-For a processing industry, a combined solution can provide, for example, cooling and freezing for production processes and canteen, air-con for the offices and heating for production processes and comfort heating.
-To ensure the most energy-efficient climate solution, more options with a noticeably short pay-back time can be provided.
-Permanent Magnet Motors are the first and obvious choice ensuring energy savings. The LSPM solution ensures a highly efficient and, at the same time, noise-reduced solution.
-With the Cylinder Unloading Technology, a better capacity regulation with fewer compressors can improve energy efficiency. Advansor has a well-proven and tested solution offering down 10 % capacity regulation on the lead compressor.
-The Ultra-Low Superheat Module allows very low returning temperature from the evaporators. Typically, the suction pressure can be increased by around 4-5 K, which reaches energy savings of around 10 %. Combined with a gas ejector, it is possible to 
  achieve additional savings of up to 20 %. The Ultra-Low Superheat module is available for Advansor racks from around 100 kW and up.
-Based on the technology and the surrounding temperatures, energy savings and pay-pack time for any solution can be estimated with the Advansor Energy Calculation Tool.
-Climate solutions are used in many different segments, from supermarkets and hotels to distribution centres and industrial production facilities fulfilling both budget and climate action goals.
