2.11 heat recovery recovery of heat rejected by the unit(s) whose primary control is in the cooling mode by means of either an additional heat exchanger (e.g. a liquid chiller with an additional condenser) or by transferring the heat through the refrigerating system for use to unit(s) whose primary control remains in the heating mode (e.g. variable refrigerant flow) 2.12 indoor heat exchanger heat exchanger which is designed to transfer heat to the indoor part of the building or to the indoor hot water supplies or to remove heat from these NOTE In the case of an air conditioner or heat pump operating in the cooling mode, this is the evaporator. In the case of an air conditioner or heat pump operating in the heating mode, this is the condenser. EN 14511-1:2004 (E) 6 2.13 outdoor heat exchanger heat exchanger which is designed to remove heat from the outdoor ambient environment, or any other available heat source, or to transfer heat to it NOTE In the case of an air conditioner or heat pump operating in the cooling mode, this is the condenser. In the case of an air conditioner heat pump operating in the heating mode, this is the evaporator. 2.14 heat recovery heat exchanger heat exchanger assembly which is designed to transfer heat to the heat recovery medium 2.15 heat transfer medium any medium (water, air, ...) used for the transfer of the heat without change of state. It can be: ¾ cooled liquid circulating in the evaporator; ¾ cooling medium circulating in the condenser; ¾ heat recovery medium circulating in the heat recovery heat exchanger 2.16 outdoor air air introduced to the conditioned space through the unit from the outside 2.17 recycled air air from the conditioned space through the unit and back to the conditioned space 2.18 exhaust air air from the conditioned space through the unit to the outdoor side 2.19 water loop closed circuit of water maintained within a temperature range on which the units in cooling mode reject heat and the units in heating mode take heat 2.20 total cooling capacity PC heat given off from the heat transfer medium to the unit per unit of time, expressed in Watt 2.21 latent cooling capacity PL capacity of the unit for removing latent heat from the evaporator intake air, expressed in Watt 2.22 sensible cooling capacity PS capacity of the unit for removing sensible heat from the evaporator intake air, expressed in Watt EN 14511-1:2004 (E) 7 2.23 heating capacity PH heat given off by the unit to the heat transfer medium per unit of time, expressed in Watt NOTE If heat is removed from the indoor heat exchanger for defrosting, it is taken into account. 2.24 heat rejection capacity heat removed by the heat transfer medium of the condenser per unit of time, expressed in Watt NOTE This applies only to heat recovery liquid chilling packages. 2.25 heat recovery capacity heat removed by the heat transfer medium of the heat recovery heat exchanger, per unit of time, expressed in (责任编辑：admin) |
