Abstract

The invention discloses an air-conditioning unit with adjustable heat exchange rate and a control method thereof, wherein the air-conditioning unit comprises: a compressor, a four-way valve, a condenser and an evaporator connected in sequence; a water tank; a refrigerant heat exchange coil and The water heat exchange coil, located inside the water tank, is used to exchange heat with the water in the water tank to produce hot water or cold water; among them, the inlet of the refrigerant heat exchange coil is connected with the refrigerant inlet of the condenser, and the refrigerant heat exchange coil The outlet of the waterway heat exchange coil is connected to the outlet of the refrigerant of the condenser; the inlet of the waterway heat exchange coil is connected to the water outlet of the air conditioning unit, and the outlet of the waterway heat exchange coil is connected to the water inlet of the air conditioning unit. The invention solves the problem in the prior art that the heating rate of hot water or cold water is too fast or too slow, resulting in poor user comfort, satisfies various needs of users for heating hot water or cold water, improves the comprehensive utilization rate of the whole machine and improves user comfort sex.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning unit with adjustable heat exchange rate and a control method thereof. Background technique [0002] At present, the hot water heating or refrigeration solutions using fluorine heat exchange in the market usually lead the condensing pipe directly into the water tank for heat exchange. Due to the problems of high exhaust pressure and high exhaust temperature of the refrigerant, the high temperature and pressure of the refrigerant will cause the water temperature of the water tank to heat up rapidly, causing the user to be scalded by the water. [0003] At the same time, in the prior art, there is also a scheme of exchanging heat between the hot water pipe and the water tank to make hot water or cool down. This scheme brings comfort but also has the problem of too slow effect, and cannot solve some urgent needs of users. [0004] For the problem in the ...
