The fundamental principle of heat pumps is to absorb heat at low-temperature levels and dispense it as useful heat at a higher temperature.<\/span><\/p>\n

A heat pump uses heat sources that are normally technically not usable. For instance, a heat pump can increase the temperature of geothermal energy from 10 \u00b0C to 40 \u00b0C. In addition to geothermal energy, it can utilise surface water and seasonal heat stores as heat sources.<\/p>\n

But a heat pump only lives up to its full potential in terms of performance and sustainability when it converts waste heat from industrial production, exhaust air from air-conditioning systems, or waste heat from chillers and then makes it available as heat output at a higher temperature level. Using a heat pump generates significant energy savings because it optimises such processes.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ _builder_version=”3.25″ custom_padding=”0px||0px”][et_pb_column type=”3_5″ _builder_version=”3.25″ custom_padding=”16px||0px|” custom_padding__hover=”|||”][et_pb_text _builder_version=”3.27.4″ text_font=”|600|||||||” text_font_size=”22px” text_line_height=”1.6em” header_font=”||||||||” header_2_font=”||||||||” header_2_font_size=”22px” header_2_line_height=”1.8em” module_alignment=”center” custom_margin=”|||” animation_direction=”left”]

Standard heat pumps are usually inadequate for heating potable water. When water is heated, temperatures of 60 to 70 \u00b0C need to be achieved in order to remove the risk of legionella.\u00a0These high temperatures are usually generated by means of inefficient electrical element heating.<\/span><\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_5,3_5″ _builder_version=”3.25″][et_pb_column type=”2_5″ _builder_version=”3.25″ custom_padding=”|||” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/sirusinternational.com\/wp-content\/uploads\/2019\/01\/thermeco2_Industrial_CO2_Heat_Pump_ENGIE.jpg” alt=”Thermeco2 high temperature heat pumps” title_text=”Thermeco2 high temperature heat pump” show_bottom_space=”off” align_tablet=”center” align_phone=”” align_last_edited=”on|desktop” _builder_version=”3.25.3″ custom_margin=”0px||0px” custom_padding=”0px||0px” animation_style=”bounce” animation_direction=”right”][\/et_pb_image][\/et_pb_column][et_pb_column type=”3_5″ _builder_version=”3.25″ custom_padding=”|||” custom_padding__hover=”|||”][et_pb_text _builder_version=”3.27.4″ text_font=”||||||||” text_font_size=”16px” text_line_height=”1.8em” header_font=”||||||||” header_2_font=”||||||||” header_2_font_size=”22px” header_2_line_height=”1.6em” module_alignment=”center” custom_margin=”|||” animation_direction=”left”]

In the long term, a trend towards natural refrigerants seems likely, due to the F-gas Regulation<\/a>, which is currently leading to restrictions on volumes of halogenated refrigerants.<\/p>\n

Refrigeration and heat pump technology is key to the future of energy-efficient building services design. If we stop generating power from fossil fuels and instead generate it from renewable energy sources whose availability is permanently shifting, we will need storage facilities to provide load balance. Thermal storage can provide this load balance. CO2<\/sub><\/span> is a highly suitable refrigerant for efficient thermal energy storage. In case of excess power in the grid, hot and\/or cold thermal energy storage units can be charged with a CO2<\/sub><\/span> heat pump and discharged again when power becomes scarce.<\/p>\n

The range of CO2<\/sub><\/span> heat pumps<\/a> from ENGIE Refrigeration comprises eleven performance classes between 45 and 1,440 kilowatts. Currently machines in the performance class of 500 to 1,000 kilowatts are the most popular. Models are also available in a hygienic stainless steel design, making them ideal for sensitive applications such as the food industry.<\/p>\n

Since that date, refrigerant filling capacities have been weighted according to their global warming potential. The F-gas Regulation is intended to reduce the volumes of fluorinated greenhouse gases (F-gases) put into circulation in the EU by 79% from 2015 levels down to 35 million tons of CO2<\/sub><\/span> equivalent by 2030.

  1. A step-by-step restriction of the F-gases available on the market; by 2030, they should be down to 21 per cent of the amounts generated in the reference years of 2013 to 2015 (phase-down scenario; see figure)<\/li>\n
  2. Prohibiting the sale of refrigerants with high GWP values<\/li>\n
  3.

This measure describes the average warming effect on the earth\u2019s atmosphere over a specific period (usually 100 years). It thereby specifies how much a defined mass of a specific greenhouse gas contributes towards global warming when compared to the same mass of CO2<\/sub><\/span>. For example, the GWP for the refrigerant R-134a for a period of 100 years is 1430.
