Heating system for compression heat pump and heating method thereof

Abstract

The invention relates to a heating system for a compression heat pump and a heating method thereof. The system comprises a compressor, a hot water tank, a throttle valve, a heat-accumulating box, a heat-collecting plate, a four-way valve and an air heat exchanger, wherein the compressor, the hot water tank, the heat-accumulating box and the air heat exchanger are respectively connected with four interfaces of the four-way valve through pipelines; and the heat-collecting plate is connected with the heat-accumulating box through a pipeline and forms a parallel-connection structure together with at least part of heat exchange coilers in the heat-accumulating box. Due to the combination of heat-collecting modes of two low-temperature heat sources, namely an air source and solar energy, the system overcomes the defect that the traditional air source heat pump cannot work at low air temperature, so that the system can provide heat for a user at the air temperature of lower than 15 DEG C below zero; the system also overcomes the defect that a solar heating system cannot work on cloudy and rainy days, so that the system can provide the heat for the user under the condition of no sunshine; and the system has a low-temperature heat source heat-accumulating function, so that the system can provide the heat for the user in the time period of no sunshine and at the air temperature of lower than 15 DEG C below zero.

Description

technical field [0001] The invention relates to a heat supply technology in the field of thermal energy engineering, in particular to a compression heat pump heat supply system and a heat supply method using solar energy, air and tap water as heat sources. Background technique [0002] Existing heating systems mainly include: fuel combustion heating systems, electric heating heating systems, air source heat pump systems, solar energy heating systems, and ground source heat pump systems. Among them, the primary energy utilization efficiency of the fuel combustion heating system and the electric heating heating system is low, and it is difficult to meet the current social needs of energy conservation and emission reduction.
