Ultraslow energy consumption system for directly adjusting indoor environment by using ground source

Abstract

The invention discloses an ultraslow energy consumption system for directly adjusting an indoor environment by using a ground source used in a building. The ultraslow energy consumption system comprises a ground source collection subsystem, a ground source storage converter, a water pump I, a water pump II, a ground source heat pump system, an indoor environment adjusting subsystem, a heat exchanger I, a heat exchanger II, a water circulation loop I, a water circulation loop II and the like together. The ultraslow energy consumption system has the characteristics that: the ground source is directly brought indoors by utilizing novel system integration of the heat exchanger, the ground source storage converter, the water pumps, the water circulation loops and the like; and the indoor environment is adjusted by the indoor environment adjusting subsystem. Due to variation in environment, the temperature of water with the ground source, which enters the indoor environment adjusting system, is required to be adjusted, the temperature of a heat transfer medium on one side of the heat exchanger II is directly or indirectly adjusted by using the ground source heat pump system, and the temperature of water in the water circulation loop II with the ground source on the other side can be adjusted. The item belongs to the fields of building energy conservation and renewable energy source utilization.

Description

Technical field [0001] The invention relates to an ultra-low energy consumption system using ground sources to directly adjust the indoor environment used in buildings. It consists of a ground source collection subsystem, a ground source storage converter, water pumps I and II, a ground source heat pump system, and indoor environment regulation. Subsystems, heat exchanger I and heat exchanger II, water circulation loop I and water circulation loop II are jointly composed. Since the ground source (the temperature at a certain depth underground, referred to as the ground source, the same below) is basically constant, it corresponds to the cold source in summer and corresponds to the heat source in winter. The system is characterized by the direct use of ground sources as the base temperature for adjusting the indoor ambient temperature. The water from the ground source enters the room, and the indoor environment temperature is adjusted by the indoor environment subsystem. In t...

Problems solved by technology

Because the change trend of air temperature in each season is consistent with the heat dissipation (cold) trend of the air conditioner main unit, the efficiency of the heat sink (cooler) used by the air conditioner main unit is limited. If a constant underground cold and heat source is used instead, the heat dissipation (cold) The efficiency is higher than that of the radiator exposed to the air, but since it is an indirect way to use the ground source to improve the efficiency of the air conditioner, there is still room for reduction in system energy consumption
