Air conditioner with heat storage device

Abstract

The invention relates to an air conditioner with a heat storage device, which comprises a compressor, a four-way valve, an outdoor heat exchanger, a first throttle valve, the heat storage device and an indoor heat exchanger, and the heat storage device is configured to be connected with the indoor heat exchanger in parallel or in series; the heat storage device is configured to enable the air conditioner to be provided with a refrigerating circuit, a heating circuit, a heat storage circuit, a quick start heating circuit and a defrosting circuit. And in the series connection mode, the heat storage device comprises a second throttling valve and a heat accumulator, and the heat accumulator comprises a first heat storage coil pipe and a second heat storage coil pipe. In the parallel connection mode, the heat storage device comprises a three-way valve, a heat accumulator and a second throttling valve. On the basis of an original air conditioner structure, the heat accumulator is used for solving the problems that in the starting stage of an existing room air conditioner, unit performance is poor, heating capacity is low, the temperature of an indoor heat exchanger is low, and a human body feels uncomfortable for a long time due to air supply.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner with a heat storage device. Background technique [0002] Room air conditioners are an important means to solve the heating demand in non-centralized heating areas in the south and decentralized heating in rural areas in the north. However, when the air conditioner has high heating wind speed in winter, strong blowing sensation, uneven indoor, cold head and hot feet, etc., people complain widely. , especially the heating performance in the starting state is often unsatisfactory. When heating operation is required, the temperature of the indoor heat exchanger is relatively low just after starting up, and the air supply makes the human body feel uncomfortable. In addition, due to the low performance of the unit and the low heating capacity when it is turned on, there will be long-term indoor discomfort. [0003] CN201910219565.1 provides a defrosting method for ...
