Seasonal-storage solar heating and combining refrigerating system and application method thereof

Abstract

The invention discloses a seasonal-storage heating and combining refrigerating system and an application method thereof. The seasonal-storage heating and combining refrigerating system comprises a solar thermal collector, an underground thermal stratification pool, a water source heat pump unit, a plate-type heat exchanger, an air conditioning terminal fan coil and a cooling tower, wherein the solar thermal collector, the underground thermal stratification pool, the water source heat pump unit, the plate-type heat exchanger, the air conditioning terminal fan coil and the cooling tower are connected together through pipelines, valves and circulating pumps. The seasonal-storage heating and combining refrigerating system provided by the invention has the advantages that the heat storage efficiency is high, the heat exchange property is good, and the operation and maintenance are simple; solar energy can replace traditional fossil fuel to provide a hot source for room heating, and thus the seasonal-storage heating and combining refrigerating system plays a positive role in environmental protection; and as solar energy is used in any season, the solar energy use ratio is improved to the maximum and can be up to more than 70%, and the purposes of energy conservation and emission reduction are fulfilled.

Description

[0001] technical field [0002] The invention belongs to the field of energy technology, and in particular relates to a solar energy cross-season heat storage-water source heat pump combined operation system and a use method thereof. [0003] Background technique [0004] With the global energy crisis and the deteriorating environment, the building energy consumption and environmental pollution caused by the urban central heating system based on fossil fuels have attracted people's attention. At present, building energy consumes about 1 / 3 of the world's energy. While building energy, it also emits a large amount of pollutants into the atmosphere, such as TSP, SO2, NOx, etc. According to the calculations of relevant departments, the CO2 emitted by building energy accounts for almost 1 / 3 of the global total emissions, which is an astonishing amount. Therefore, developing new environmentally friendly renewable energy and improving the energy utilization efficiency of heating...

Problems solved by technology

[0005] In the northern alpine region, the temperature is low in winter, the sunshine time is short, only 5-6 hours, the effective solar radiation is small, it is difficult to meet the heating needs; in summer, the temperature is generally high and there is little rain, the sunshine time is longer, more than 12 hours, and the solar energy is abundant , and this season cannot effectively use solar energy for heating in winter
