Abstract

The invention discloses a PVT composite device based on combination of nocturnal radiation and dew point evaporative cooling. The device comprises a coupling radiation PVT, one side of the coupling radiation PVT is connected with an air inlet, the coupling radiation PVT is connected with a heat storage water tank through a liquid inlet pipe and a liquid outlet pipe, one side of the coupling radiation PVT is electrically connected with a controller, the controller is electrically connected with a storage battery and an electric load, the side, far away from the air inlet, of the coupling radiation PVT is provided with an air outlet, the side, close to the air outlet, of the coupling radiation PVT is provided with a shell, the side, close to the coupling radiation PVT, of the shell is provided with a wind inlet, the interior of the shell is connected with a dew point evaporative cooling mechanism, an electric heating pipe I is arranged above the dew point evaporative cooling mechanism, and the top of the shell is fixedly connected with a fan I and a fan II. The PVT composite device has the beneficial effects that the influence of day and night change and seasonal change on the utilization rate of the device is overcome, and the equipment utilization rate and the space utilization rate are improved.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a PVT composite device and an air conditioner based on nighttime radiation combined with dew point evaporative cooling. Background technique [0002] Dew-point evaporative cooling air conditioners are based on evaporative cooling technology, which mainly uses dry air energy and uses the temperature difference between dry and wet bulbs of outdoor air as the driving potential for air conditioning. The dew point evaporative cooling air conditioner has a compact structure and a remarkable cooling effect. But it can only be used for cooling in summer, not for heating in winter, with single function and low utilization rate of equipment. [0003] Radiation cooling refers to a passive cooling method in which objects on the ground exchange heat with outer space at a very low temperature through the 8 μm ~ 13 μm band of one of the “atmospheric windows” to achieve a certain coo...
