Claims

[Scope of utility model registration request]

The outside air introduction duct is branched into a first and second air conditioning duct, and the first air conditioning duct houses a first heat exchanger with a small capacity, and the second air conditioning duct houses a second heat exchanger with a large capacity. The first air conditioning duct is connected to the first air conditioning duct downstream of the first heat exchanger.
, branching into a second branch duct, placing the second air conditioning duct downstream of the second heat exchanger and branching into third and fourth branch ducts, and connecting the first and third branch ducts to a first duct having a discharge port. The second and first branch ducts are connected to a second branch duct having a discharge port.
The air-conditioned air in the first and second air conditioning ducts is communicated with the first and second ducts, and the air-conditioned air in the first and second air-conditioning ducts is alternately communicated with the first and second ducts at the branching parts of the first and second branching ducts and the third and fourth branching ducts. A damper is provided that opens and closes each branch duct synchronously and periodically to allow the flow to flow periodically.
, a fan is installed in the second air conditioning duct to send air to the downstream side,
Directly downstream of each fan, the first and second air conditioning ducts
, a second temperature sensor is provided, and signals from the first and second temperature sensors are used to control the first and second heat so that the temperature difference and the lower limit temperature of the air conditioning airflow in the first and second air conditioning ducts become predetermined values. A temperature pulsating air conditioner characterized by being provided with a control mechanism that controls the flow rate of cold water supplied to an exchanger.
