Combined heat pump system with solar injection and solar photovoltaic steam injection and compression

Abstract

The invention discloses a combined heat pump system with solar injection and solar photovoltaic steam injection compression. The system consists of a solar injection system and a solar photovoltaic steam injection and compression system, the solar injections system consists of a heat collection system and an injection system, the solar photovoltaic steam injection and compression system is composed of a steam injection and compression system, an air energy dual-level steam compression auxiliary system and an solar photovoltaic power generation system. In a refrigerating station, when solar energy is not collected, the air energy dual-level steam compression auxiliary system is used by the system; when the collected energy is not enough, an overlapping circulating system and the air energy dual-level steam compression auxiliary system are used for circularly and simultaneously cooling; when the collected solar energy meets the refrigerating demand, the overlapping circulating cooling can be used by the system; in a heating station, the air energy dual-level steam compression auxiliary system is used for circularly heating with solar energy or air by the system. The heat can be provided by the solar photovoltaic power generation system in all conditions.

Description

technical field [0001] The present invention relates to a heat pump system, more specifically, relates to a combined heat pump system of solar injection and solar photovoltaic steam injection compression. Background technique [0002] Solar energy is an inexhaustible, inexhaustible and non-polluting ultra-clean renewable energy. In the current situation of high oil prices and intensified global warming, the development and utilization of this renewable energy is of great significance. At the World Solar Energy Conference held in 1999, some experts believed that there are two basic trends in the development of solar energy technology in the contemporary world. [0003] At present, there are two main ways to apply solar energy to air conditioners. One is to use photovoltaic modules to convert solar energy into electrical energy to provide electrical energy for vapor compression air conditioners. In this case, the operating efficiency of the air conditioner has not been signif...
