Embodiment Construction

[0033] The present invention will be further illustrated in a non-limiting manner below in conjunction with the accompanying drawings and examples.

[0034] In summer, the shut-off valve (21) is always on. During the day, the user can control the indoor thermostat (26) to open or close the corresponding electric valve, so that the absorption refrigeration cycle unit (301) uses solar heat circulating water as the only heat source. Use the hot water in the solar thermal cycle tube (2) to heat the working medium solution with a certain concentration that is transported from the absorber (15) to the generator (12) by the pump (16), and make the low boiling point refrigerant in the solution evaporated, enters the condenser (13) through the vacuum pipe (11), and is condensed into a refrigerant liquid by the cooling water delivered by the cooling water pipe (20) inside it, and then depressurized to The evaporating pressure enters the evaporator (14), and the refrigerant liquid in th...

Abstract

The invention relate to a cooling and heating combined dual-supply system combined with solar energy. The system is characterized by comprising a solar energy heat cycle unit (101), a gas heat cycle unit (201), an absorption refrigeration cycle unit (301), an air conditioning cycle unit (401) and a floor heating cycle unit (501); starting and stopping of the solar heat cycle unit and the gas heatcycle unit are switched by controlling on or off of corresponding electric valves; the solar heat cycle unit and the gas heat cycle unit are connected with the air conditioning cycle unit and the floor heating cycle unit by the absorption refrigeration unit or a heat supply water supply pipe (9) and a heat supply return pipe (10), operation is performed on an indoor temperature controller (26), and a system controller (25) controls on or off of the corresponding electric valves to select the connection mode, so that cooling or heating of a fan coil and floor heating is achieved.

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. 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 healthy, comfortable, green and e...
