Solar-energy-combined cold and warm dual power supply system and control method thereof

Abstract

The invention relates to a solar-energy-combined cold and warm dual power supply system and a control method thereof. The solar-energy-combined cold and warm dual power supply system is characterizedin that the system comprises a solar energy heat cycle unit (101), a gas heat cycle unit (201), an absorbed refrigeration cycle unit (301), an air conditioner cycle unit (401) and a floor heating cycle unit (501); the start and stop of the solar energy heat cycle unit and the gas heat cycle unit are switched mutually by controlling the switch of a corresponding electric valve; and the connection modes of the solar energy heat cycle unit and the gas heat cycle unit, the air conditioner cycle unit and the floor heating cycle unit are through the absorbed refrigeration unit or a heating water supply pipe (17) or a heating water return pipe (18), through the operation on an indoor temperature controller (41), a system controller (40) controls the switch of the corresponding electric valve to select the connection mode, and thus the cooling or heating of a fan coil and the floor heating is achieved. According to the solar-energy-combined cold and warm dual power supply system, the effectiveuse time of the floor heating is prolonged, the load power of the fan coil is further reduced, thus the regulation process of the indoor environment is more energy-saving, and the body feeling is more comfortable.

Description

technical field [0001] The invention relates to a cooling and heating dual-connection dual-supply system, in particular to a cooling and heating dual-connection dual-supply system combined with solar energy and a control method thereof. Background technique [0002] With the continuous development of my country's national economy and the continuous improvement of the living standards of urban and rural people, along with the improvement of living conditions comes the rapid growth of building energy consumption. At present, building energy accounts for nearly 40% of the energy consumption of the whole society, exacerbating the tension of energy supply. At the same time, people have poor experience with the current cooling and heating environment in winter and summer, especially the environmental comfort of cooling in summer, and it has given birth to a common modern urban disease - air conditioning disease. In order to reduce building energy consumption while creating a heal...
