Voorbeeldzinnen

1. Incorporating a refrigerating unit and a valve for reversal of the cooling/heat cycle (reversible heat pumps)
2. Incorporating a refrigerating unit and a valve for reversal of the cooling/heat cycle (reversible heat pumps):
3. The Vsec is determined by continuous flow measurement e.g. before the heat recovery unit.
4. Examples of fuel inputs are any combustibles, steam and other heat imports, and process waste heat used in the cogeneration unit for electricity generation [4].
5. Exported heat used in power generation on another site does not qualify as useful heat but is considered as a part of the internal heat transfer within a cogeneration unit.
6. A cogeneration unit operating with maximum technically possible heat recovery from the cogeneration unit itself is said to be operating in full cogeneration mode.
7. Examples of heat other than useful heat are the following: heat rejected to the environment without any beneficial use [3]; heat lost from chimneys or exhausts; heat rejected in equipment such as condensers or heat-dump radiators; heat used internally for de-aeration, condensate heating, make-up water and boiler feed-water heating used in the operation of boilers within the boundaries of the cogeneration unit, such as heat recovery boilers.
8. Including unavoidable thermal energy losses and ‘non-economically justifiable demanded’ heat produced by the co-generation unit.
9. ‘boiler’ means the combined boiler body-burner unit, designed to transmit to fluids the heat released from burning;
10. If the tourist accommodation service has such cogeneration unit on site its output of heat and electricity shall supply at least 70 % of the total heat and electricity consumption on site.
11. If the heat pump is reversible and can cool, then the efficiency of the heat pump unit shall exceed the following minimum requirements of the energy efficiency ratio (EER) in cooling mode.
12. Non-CHP fuel energy means the fuel energy, based on lower heating value, needed in a CHP unit for heat production not considered to be useful heat and/or non-CHP electrical energy in a reporting period (see Figure 1).
13. If the campsite service has such cogeneration unit on site its output of heat and electricity shall supply at least 70 % of the total heat and electricity consumption on site.
14. If the actual ‘power to heat ratio’ of the cogeneration unit is not known, the plant operator can use the default ‘power to heat ratio’ (Cdefault), as specified in Annex II to Directive 2004/8/EC, to calculate CHP electricity.
15. Other heat or electricity production equipment such as heat-only-boilers and electricity-only-power units that do not contribute to a cogeneration process shall not be included as part of the cogeneration unit as illustrated in Figure 3.
