Problems solved by technology

The time for hot water for bathing or heating by the above-mentioned equipment is much longer than that for cooling, so a large amount of residual cold generated from it is discharged outdoors or underground, causing great waste
[0003] So far, there is no refrigerant circulation device for waste cold recovery on the market

Embodiment 1

[0027] figure 1 , A hot water air conditioner with a waste cold recovery device, and a refrigerant circulation device for supplying cold air and hot water for bathing at the same time. At this time, the water tank heat exchanger device 2 is a heat exchanger device with a coil pipe placed in the inner container, the indoor unit 7 is an air conditioner indoor unit, and the outdoor heat exchanger device 4 is an outdoor condenser device of the air conditioner. The arrow points to the refrigerant flow direction of the hot water air conditioner. When the hot water air conditioner cools the air, the compressor 1 starts to run. The refrigerant is from compressor 1→water tank heat exchanger device 2→four-way valve 3→outdoor heat exchanger device 4→waste cold recovery device 5→throttle valve 6→indoor unit 7→gas-liquid separator 8→compressor 1. Since the water tank heat exchanger device 2 is arranged between the compressor 1 and the four-way valve 3 . Therefore, the high-temperature r...

Embodiment 2

[0030] figure 2 , A hot water air conditioner with a waste cold recovery device, and a refrigerant circulation device for heating and bathing hot water at the same time. At this time, the water tank heat exchanger device 2 is a heat exchanger device with a coil pipe coiled outside the inner tank, the indoor unit 7 is an air conditioner indoor unit, and the outdoor heat exchanger device 4 is an outdoor condenser device of the air conditioner. The arrow points to the refrigerant flow direction of the hot water air conditioner. When the hot water air conditioner supplies heating or hot water for bathing, the compressor 1 starts to run. The refrigerant is from compressor 1→water tank heat exchanger device 2→four-way valve 3→indoor unit 7→throttle valve 6→waste cold recovery device 5→outdoor heat exchanger device 4→gas-liquid separator 8→compressor 1. Same as Embodiment 1, the water tank heat exchanger device 2 can supply hot water for bathing indoors. The waste cold recovery d...

Embodiment 3

[0034] image 3 , Air source "triple supply" heat pump with residual cold recovery device, and refrigerant circulation device for heating hot water and hot water for bathing at the same time. At this time, the water tank heat exchanger device 2 is a plate heat exchanger device with external hot water supply equipment; the outdoor heat exchanger device 4 is an outdoor condenser device for an air conditioner; Plate heat exchanger installation for hot water equipment. Since the flow direction of the product refrigerant is the same as in Embodiment 2, the waste cold recovery device 5 has the function of waste cold recovery.

Abstract

The invention discloses the technical scheme of a refrigerant circulating device used for residual cool recycling. The refrigerant circulating device used for residual cool recycling comprises a compressor, a water tank heat exchanger device, a four-way valve, an outdoor heat exchanger device, a residual cool recycling device, a throttling valve, an indoor unit and a gas and liquid separator and is characterized in that the residual cool recycling device is arranged between the outdoor heat exchanger device and the throttling valve. According to a hot water air conditioner, a triple generation heat pump unit and household central type heating and ventilation products produced through the technical scheme, during hot air and hot water making, residual cool generated by the device can be sufficiently recycled and used, and the power saving effect can be achieved to the larger degree.

Description

technical field [0001] The present invention is suitable for household central heating and ventilation products combined with refrigerators and air-conditioning fans, central heating, cooling, and hot water supply. It belongs to the field of household appliances. Specifically: it relates to a refrigerant circulation device for waste cold recovery. Background technique [0002] Hot water air conditioners, "triple supply" heat pump units, and other household central heating and ventilation products currently used in the market. They all have the functions of central heating, cooling, and hot water for bathing. When they are cooling, some equipment uses water tanks to recover waste heat, and some equipment does not recover waste heat. However, when they are heating or hot water, they do not recycle residual cold. The time for hot water for bathing or heating by the above-mentioned equipment is much longer than that for cooling, so a large amount of residual cold generated t...
