Abstract

The invention discloses an embedded pipe type enclosure structure radiant cooling control system and method. The system comprises a radiant cooling tail end mechanism, a dehumidification ventilation mechanism, a cold and heat source heat exchange mechanism and a control module. The cold and heat source heat exchange mechanism comprises a cold and heat source unit and a heat exchange mechanism. Theheat exchange mechanism comprises a plate heat exchanger, a electromagnetic three-way valve, a first circulating water pump and a second circulating water pump. An indoor humidity sensor, an indoor dry-bulb temperature sensor, a dew point temperature sensor, a wind speed sensor, a black globe temperature sensor and a surface temperature sensor are arranged in a room. The method comprises the following steps of 1, parameter setting; 2, signal real-time acquisition and synchronous uploading; 3, adjustment of the radiant tail end cooling water temperature; and 4, adjustment of the heat comfort index PMV value. The embedded pipe type enclosure structure radiant cooling control system and method are applicable to outdoor temperature variation and indoor temperature and humidity variation so that the indoor heat environment can meet the requirements of indoor personnel for heat comfort and energy consumption can be reduced.

Description

technical field [0001] The invention belongs to the technical field of radiant end cooling control of an embedded tube type enclosure structure, and in particular relates to a radiation cooling control system and method for an embedded tube type enclosure structure. Background technique [0002] The embedded tube enclosure structure radiant cooling system is also called concrete radiant cooling system. The water supply pipe is buried in the enclosure structure, such as a concrete floor, and the heat is transferred through the flow of water in the pipe to achieve the cooling effect. Due to the high thermal inertia of the cold roof (floor) plate itself, the control of this system is different from that of conventional air conditioners. When the surface temperature of the radiant cooling component is lower than the dew point temperature of the indoor air, condensation may occur and affect the indoor air quality. In addition, the current radiant cooling system mostly adopts the...
