The Design Of Ground Source Heat Pump Central Air Conditioning Temperature Control System

The central air-conditioning of geothermal heat pump, which is a application of the renewable geothermal energy resources, is an advanced, high efficiency, energy-saving, environmental protection of air conditioning system. It is an application of the renewable energy resources. Facing the increasingly serious environmental problems and energy shortage, reasonable and efficient utilization of the geothermal resources is the effective way to solve the environmental and energy problems.For the demands of energy saving and load balancing of ground-source heat pump air-conditioning, variable water flow systems of air-conditioning were studied in this paper. After making use of fuzzy optimization control algorithm and variable frequency technology, the research work has brought about a variable water flow control system for energy saving of ground source heart pump in air conditioning based on fuzzy control. The expert experience and control rules are integrated with the system. Independent of the accurate mathematical model, the system has an excellent control performance and wonderful dynamic adaptability.This paper introduces a design of Geopolitical heat pump central air conditioning temperature and humidity automatic control system based on single-chip microcomputer control technology. The system uses temperature sensor AD590and HS1101humidity sensors to obtain and control of temperature and humidity respectively, and uses the A/D converter to convert them to digital signals. When the temperature and humidity are higher than normal temperature and humidity, the automatic alarm device operates, at the same time, the ground source heat pump air conditioning is opened, and it will restore the normal temperature and humidity through digital tube display. The system is testing system for SCM (Single Chip Micyoco), including temperature, humidity sensors, the circuit, signal amplifier circuit filter circuits, A/D circuit and other electronic circuit, relays, singlechip hardware electronic circuit. The system can control, display,process and transmit information automaticly. The system is mainly designed through software programming,which can test the temperature and humidity and provide automatic alarm. This system can test, control real-timely and have good stability and simple operation. It can be widely used in daily household air conditioning control aspect.
