Embodiment Construction

[0025] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0026] like figure 1 As shown, this embodiment is based on a heat pump system for solar heat storage, defrosting, supplementary air, and enthalpy increase, including: a compression refrigeration subsystem and a solar heat storage subsystem. When the system stores heat, the solar heat storage subsystem and the compression refrigeration subsystem The subsystems are arranged in parallel, and when the system is defrosting, the solar thermal storage subsystem and the compression refrigeration subsystem are arranged in series.

[0027] Wherein, the compression refrigeration subsystem includes a compressor 1, an indoor heat exchanger 2, an energy storage heat exchanger 4, an economizer 5, an outdoor heat exchanger 6, a gas-liquid separato...

Abstract

The invention discloses an air-replenishment and enthalpy-increment heat pump system based on solar heat storage defrosting. The system comprises a compression refrigerating subsystem and a solar heatstorage subsystem; when the system stores heat, the solar heat storage subsystem and the compression refrigerating subsystem are arranged in parallel; and when the system defrosts, the solar heat storage subsystem and the compression refrigerating subsystem are arranged serially. Compared with the prior art, the system can use solar energy and heating cycle afterheat for defrosting to synchronously achieve the technical effects of defrosting and energy conservation.

Description

technical field [0001] The invention relates to the technical field of heat pump defrosting, and more specifically, relates to a heat pump system based on solar heat storage and defrosting to supplement air and increase enthalpy. Background technique [0002] The air source heat pump is an energy-saving device based on a low-temperature heat source that uses low-grade heat energy in the air to produce hot water or air that is higher than the ambient temperature. As a low-level heat source, the air source has abundant reserves, and compared with the traditional heating method, the air source heat pump not only reduces energy consumption, but also reduces environmental pollution. The promotion of air source heat pump technology has extensive application value in energy saving, emission reduction and environmental protection. [0003] The operation of air source heat pumps is greatly affected by the temperature and humidity of the surrounding environment. When operating in col...
