Cascade energy usable variable capacity family energy resource system

Abstract

The present invention provides an adjustable volume family energy system utilized by step energy, the invention includes a compressor, a hot water heat exchanger, a four-way reversing valve, an outdoor wind cooling pipe coil, a first check valve, a second check valve, a first electronic expansion valve, a second electronic expansion valve, an air conditioning hot and cold heat exchanger, a gas-liquid separator, a water side electric three-way control way, a first solenoid valve, a second solenoid valve, a first water pump, a second water pump. These parts form a refrigerant loop, a domestic hot-cold water loop, realize refrigerating and hot water supplying, single refrigerating, single hot water supplying, single warm supplying, warm supplying and hot water supplying five modes. The control part of the refrigerant loop only has four-way reversing valve and electronic expansion valve in traditional air conditioning system, does not exist refrigerant potential safety hazard. The function of each system is mainly realized by switch and adjustment of the water side two solenoid valves and electric three-way control way, has a simple control, credible security.

Description

technical field [0001] The invention relates to a system in the technical field of thermal engineering, in particular to a family energy system with adjustable capacity for cascaded energy utilization. Background technique [0002] With the development of science and technology and the progress of society, in the process of understanding and transforming nature, human beings are gradually beginning to pay attention to strengthening the awareness of protecting nature and putting it into practical actions. At the same time, environmental protection puts forward higher requirements for science and technology. In recent years, the depletion of the ozone layer has become increasingly serious and global warming has led to continuous progress in the field of air conditioning to high-efficiency, energy-saving, and environmentally friendly refrigeration technologies. [0003] In the current family life, household water heaters and heat pump air conditioners are indispensable necessi...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to address the deficiencies of the prior art, to provide a family energy system with adjustable capacity for cascade energy utilization, so as to solve the problems of low hot water supply efficiency and many safety hazards in the current household cold and heat energy supply, and the air conditioner in summer. There is a large amount of condensed waste heat, forming the urban heat island effect, and the problem of long idle time in transitional seasons
