Improved heating and cooling air conditioning water heater

Abstract

The invention discloses an improved heating and cooling air conditioning water heater which comprises a compressor air exhaust end, a hot water exchanger, a first four-way valve, an outdoor machine heat exchanger, a first throttling device, an indoor machine heat exchanger, a second four-way valve, a first four-way valve and a compressor air absorption end which are connected with one another, wherein the first throttling device is communicated with the indoor machine heat exchanger in positive and negative directions; in four pipelines of the second four-way valve, one pipeline is plugged and other pipelines are connected with the first four-way valve, the indoor machine heat exchanger and the compressor air absorption end respectively; and at the same time, switch-on or switch-off amongthe pipelines is controlled according to power-on or power-off. When the improved heating and cooling air conditioning water heater runs, the four-way valves and other electromagnetic valves have no high temperature demagnetization phenomena; furthermore, when the improved heating and cooling air conditioning water heater runs, a coolant stream is smooth in the positive and negative directions and cannot be stopped; when hot water is made independently, the coolant in an indoor machine can flow back to a compressor slowly, and the coolant cannot be stopped and participates in the running of the system; meanwhile, the design of the system is applicable to air conditioning water heaters of any specifications.

Description

technical field [0001] The invention relates to the field of air conditioner water heaters. Background technique [0002] Existing air-conditioning water heaters that have both air-conditioning functions and can prepare hot water have a structure in which a hot water exchanger is connected in series at the high-pressure exhaust port of the compressor, and the other end of the hot water exchanger is connected to the high-pressure side of the four-way valve. The left and right loops of the through valve are respectively connected to the outdoor unit heat exchanger and the indoor unit heat exchanger. The low-pressure side of the four-way valve is connected to the low-pressure suction port of the compressor. The capillary tube or expansion valve as the throttling device is connected in series between the outdoor unit heat exchanger and the indoor unit heat exchanger. With such a single throttling configuration, the refrigerant flow cannot be adjusted. When the outdoor ambient ...

Problems solved by technology

However, due to the structural characteristics, functional limitations and specifications of the refrigeration device, this system cannot be well applied to air-conditioning water heaters of various specifications from small to large. Moreover, the functions of some components in the system are It cannot meet the requirement of heating hot water alone and allowing the air conditioner to operate in two states of cooling or heating, so it still needs further improvement
