RoomAirExchange

class iesve.RoomAirExchange

Bases: object

Interface for Room Data: Air Exchanges. Used by VERoomData class to return air exchanges data for a room. The following Air Exchange types are supported:

• Infiltration

• Natural Ventilation

• Auxiliary Ventilation

get() → dict

Returns a dictionary containing the data for an air exchange. The following fields are returned:

Key	Description
adjacent_condition_string	(string)
adjacent_condition_val	(int) iesve.AdjacentCondition_type
adjacent_condition_val_from_template	(Bool)
max_flow_from_template	(Bool)
max_flows	(Dictionary of 4 floats, indexed by integer) Represent the various flow conversions
name	(string)
offset_temperature	(float) Only present when adjacent_condition == 2
temperature_profile	(string) Profile ID, only present when adjacent_condition references a profile)
temperature_profile_from_template	(Bool)
type_val	(int) iesve.AirExchange_type
units_strs	(Dictionary of strings, indexed by integer) String representations of units for max_flows
units_val	(int) See iesve.AirChange_unit
variation_profile	(string) Profile ID
variation_profile_from_template	(Bool)

set(data: dict)

Sets the room air exchange using a dictionary. Keys are the same as the get() dict, however:

• ‘name’, ‘type_val’, ‘type_str’, ‘units_strs’, ‘max_flows’ and ‘adjacent_condition_string’ will be accepted but will not set values

• Relevant enums required for set function, using int will result in an error.

• ‘max_flow’(double) is an additional/optional key that sets the max flow value in the defined units type (units_val). This optional takes the air exchange off template.

adjacent_condition: AdjacentCondition_type

adjacent condition property. Modifiable.

Modifying this will set adjacent_condition_uses_template to False

adjacent_condition_from_template: bool

if adjacent_condition taken from template. Modifiable.

Setting to True will reset it

air_change_rate_from_template: bool

if max_flow and air_change_unit taken from template. Modifiable.

Setting to True will reset them

air_change_unit: AirChange_unit

airchange flow unit property. Modifiable. Modifying this will set iesve.RoomAirExchange.air_change_rate_from_template to False

exchange_type: AirExchange_type

airchange type property. Read only.

max_flow: float

Max airchange rate. Modifiable. Units are set in ‘air_change_unit’ property. Modifying this will set iesve.RoomAirExchange.air_change_rate_from_template to False.

Value between 0 and 5000 ACH when modifying, values in other units will be converted before validation

offset_temperature: float | None

air offset temperature. Modifiable. Modifying this will set offset_temperature_uses_template to False.

Will return None if adjacent condition is not ‘external_air_and_offset_temp’

Value between -50 and 50 deg C

offset_temperature_from_template: bool

if offset_temperature taken from template. Modifiable.

Setting to True will reset it

temperature_profile_id: str

temperature profile id. Modifiable. Modifying this will set temperature_profile_id_uses_template to False.

Will return None if adjacent condition is not ‘external_air_and_offset_temp’

temperature_profile_id_from_template: bool

if temperature_profile_id taken from template. Modifiable.

Setting to True will reset it

variation_profile_id: str

variation profile id property. Modifiable. Modifying this will set iesve.RoomAirExchange.variation_profile_id_from_template to False.

Note: Make sure to use an ID that exists, as value will not be verified.

variation_profile_id_from_template: bool

if variation_profile_id taken from template. Modifiable.

Setting to True will reset it
