Air- solar energy double heat source synchronous composite type heat pump device

Abstract

The present invention provides an air-solar dual-heat source synchronous composite type heat pump apparatus, which comprises a solar collecting and storage part, and an air-liquid dual-heat source synchronous composite type solar heat pump part. Wherein, the solar collecting and storage part comprises a solar collector (4), a solar storage water tank (5), a living water tank (6), a heat exchanging coil pipe (17), a first circulation water pump (7), a second circulation water pump (8), a connecting pipeline and a valve. The composite type solar heat pump part comprises a compressor (1), a fin sleeve casing composite type heat exchanger (2), a user side heat exchanger (3), a first capillary tube (13), a second capillary tube (14) and a check valve (15), a four-way reversing valve (16), and the connecting pipeline and the valve and so on. The heat exchanger (2) comprises an outer sleeve casing (22), an inner sleeve casing (23) through arranged inside the outer sleeve casing and a fin (21) combined with the outer wall of the outer sleeve casing. A ring type space existed between the outer wall of the inner sleeve casing and the inner wall of the outer sleeve casing is a medium channel (19), and another medium channel (18) is formed by a pipe cavity of the inner sleeve casing. A third kind of medium channel (20) is formed between the outer wall of the outer sleeve casing and the fin.

Description

technical field [0001] The invention relates to the fields of air source heat pump air conditioning and solar heat utilization, in particular to an air-solar dual heat source synchronous composite heat pump device. Background technique [0002] At present, energy shortage and environmental pollution have become two prominent problems restricting global sustainable development, and have attracted more and more attention from all countries in the world. The shortage of energy is manifested in two aspects: on the one hand, the main body of the global energy system is "carbon-based energy" - oil and coal, and these non-renewable energy sources have been exhausted; on the other hand, the rapid expansion of global energy consumption and energy consumption Waste is serious, further exacerbating the energy shortage. In addition, with the development of society and the improvement of people's living standards, energy consumption for heating, air conditioning and domestic hot water p...

AI Technical Summary

Problems solved by technology

The main feature of the above solar heat pump system is that the solar heat exchangers are connected in series and in parallel. Although the solar heat pump can use two kinds of heat sources, it needs to add additional solar heat exchangers, which increases the complexity of the system and equipment investment. The solar heat pump implements switching between two heat sources, and cannot use both air and solar heat sources at the same time
