Air Exchange

class iesve.AirExchange

Bases: object

Represents Air Exchange template data for the following:

• Infiltration

• Natural Ventilation

• Auxiliary Ventilation

get() → dict

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

Key	Value
adjacent_condition_string	(str)
adjacent_condition_val	(int) see iesve.AdjacentCondition_type for values
max_flow	(float)
name	(str)
offset_temperature	(float)
temperature_profile	(str) profile ID
type_str	(str) ‘Infiltration’, ‘Natural Ventilation’, or ‘Auxiliary ventilation’
type_val	(int) see iesve.AirExchange_type for values
units_str	(str) ‘ach’, ‘l/s’, ‘l/s/m²’, ‘l/s/person’, ‘l/(s.m² fac)’
units_val	(int) see iesve.AirChange_unit for values
variation_profile	(str) profile ID

set(data: dict)

Set the air exchange using a dictionary. Keys are the same as the get() dict.

Note ‘type_str’, ‘units_str’, and ‘adjacent_condition_string’ will be accepted but will not set.

Relevant enums required for set function, see below, using int will result in an error

adjacent_condition: AdjacentCondition_type

adjacent condition property. Modifiable.

air_change_unit: AirChange_unit

airchange flow unit property. Modifiable

exchange_type: AirExchange_type

airchange type property. Modifiable.

max_flow: float

Max airchange rate. Modifiable. Units are set in ‘air_change_unit’ property

name: str

Descriptive string

offset_temperature: float | None

air offset temperature. Modifiable.

Will return None if adjacent condition is not ‘external_air_and_offset_temp’ Value between 0 and 20000 when modifying

temperature_profile_id: str | None

temperature profile id. Modifiable. Will return None if adjacent condition is not ‘temperature_from_profile’.

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

variation_profile_id: str

variation profile id property. Modifiable. Note: Make sure to use an ID that exists, as value will not be verified
