Abstract

The invention provides a heat exchange system and a water heater with the same. The heat exchange system comprises an exhaust opening of a compressor, wherein the exhaust opening communicates with a first inlet end of a first heat exchanger, a first outlet end of the first heat exchanger communicates with a first inlet end of a second heat exchanger, the first outlet end of the first heat exchanger communicates with an inlet end of a third heat exchanger, an outlet end of the third heat exchanger communicates with a first inlet end of a gas-liquid separator, and a first outlet end of the gas-liquid separator communicates with an intake opening of the compressor; and a caterpillar pipe and a valve structure are arranged on a pipeline for connecting the second heat exchanger and the third heat exchanger, and the caterpillar pipe and the valve structure are arranged in parallel. By arranging the caterpillar pipe and the valve structure side by side, the low-temperature back-flowing and high-temperature overheating problems of the heat exchange system can be prevented, the liquid impact condition of the compressor is effectively avoided, the practicability and reliability of the heat exchange system are effectively improved, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange system equipment, in particular, to a heat exchange system and a water heater having the same. Background technique [0002] Existing CO with capillary throttling 2 Heat pump water heaters are prone to liquid back when heating at low temperatures, resulting in compressor liquid hammer. Easy to overheat under high temperature conditions, limiting CO 2 Due to the performance of the refrigerant characteristics, the operating range of the working conditions is small, and the environmental adaptability is poor. Based on the current technical limitations of electronic expansion valves under high pressure conditions, using one electronic expansion valve alone often fails to meet the regulation requirements, and the use of multiple electronic expansion valves will generate cost pressure, thus resulting in poor user experience of heat pump water heaters in the prior art The problem. Contents of ...
