Multi-on-line air conditioning and water heating integration machine

Abstract

The invention discloses a multi-on-line air conditioning and water heating integration machine. The multi-on-line air conditioning and water heating integration machine comprises multiple indoor units, a water heating module and an outdoor unit. Each indoor unit comprises an indoor heat exchanger and an indoor electronic expansion valve. The water heating module comprises a water tank heat exchanger. The outdoor unit comprises a compressor, an outdoor heat exchanger and an outdoor electronic expansion valve. When hot water is needed, the compressor, the water tank heat exchanger, the indoor electronic expansion valves, the indoor heat exchangers and the compressor communicate in sequence to form a first refrigerant loop to produce hot water, and the indoor units conduct refrigeration; or the first refrigerant loop and a second refrigerant loop formed by communicating the compressor, the water tank heat exchanger, the outdoor electronic expansion valve, the outdoor heat exchanger and the compressor communicate in sequence produce hot water together, and the indoor units conduct refrigeration; or the second refrigerant loop produces hot water separately, and the indoor units conductheating or are stopped. According to the multi-on-line air conditioning and water heating integration machine, indoor unit can be recovered to produce hot water during air conditioner refrigeration, meanwhile hot water can be produced through circulation of refrigerants during air conditioner heating or air conditioner stop, and energy resources are saved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a multi-connected air conditioner and hot water integrated machine. Background technique [0002] Air conditioning and hot water are indispensable in daily life. Existing a large amount of air conditioners and water heaters combine the product on the market. A small amount of these products use the waste heat generated by air conditioning to produce hot water, but most of them use the waste heat of large air-cooled chillers for commercial hot water applications, and are rarely used in domestic air conditioners. Because household air conditioners mostly use unit air conditioners, although it is relatively easy to realize the two-in-one air conditioner and hot water, the efficiency of a single air conditioner for heating hot water is not high, and the waste heat of other air conditioners during cooling will cause waste. In addition, unit-unit air-conditioning...

Problems solved by technology

Because household air conditioners mostly use unit air conditioners, although it is relatively easy to realize the two-in-one air conditioner and hot water, the efficiency of a single air conditioner for heating hot water is not high, and the waste heat of other air conditioners during cooling will cause waste.

In addition, unit-unit air-conditioning hot water products cannot produce hot water when the air conditioner is heating, which has certain limitations
