An Intelligent Control System Applicable to Fan Coil Control Valve

Abstract

An intelligent control system suitable for a fan coil control valve is applied to a central air-conditioning system and comprises a lock tongue induction device; the lock tongue induction device can induct whether a lock is in a locking state or not and is connected with a second power source and a base electrode of a triode Q1; a collector electrode of the triode Q1 is connected with a base electrode of a triode Q2 through a resistor R1; an emitting electrode of the triode Q2 is connected with the ground; a collector electrode of the triode Q2 is connected with a first power source through the fan coil control valve; the first power source is connected with the collector electrode of the triode Q2 through a stabilivolt D1; and an emitting electrode of the triode Q1 is connected with a third power source. According to the intelligent control system, the situation that heating / cooling of a central air conditioner to the interior of an office is automatically controlled when no person is in the office or after work can be achieved without delaying the using condition of the interiors of other offices, accordingly the utilization efficiency of the central air conditioner is improved, and energy is saved.

Description

technical field [0001] The invention relates to the field of central air-conditioning control, in particular to an intelligent control system suitable for a fan coil control valve. Background technique [0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling load of the indoor environment. The refrigeration system is a crucial part of the central air-conditioning system, and its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the central air-conditioning system in operation. [0003] At present, the central air-conditioning equipment used in office buildings suppli...

Problems solved by technology

[0003] At present, the central air-conditioning equipment used in office buildings supplies warm air or cold air to each office through the fan coil unit, and each office is individually controlled. By adjusting the fan coil unit, when there is no one in the office or when you forget to turn off the air conditioner after get off work, the existing measure is to turn off the central air conditioner. The switch is complicated to operate, and it is impossible to control the temporary overtime situation in real time
