In the winter time, have in the process of hot water of first temperature or second temperature, be arranged on first heat exchanger 12 in the outdoor unit 10 and can produce frost in generation as mentioned above.At this moment, the rate of heat exchange between first cold-producing medium and the outdoor air can reduce, thereby makes the performance degradation of supply equipment.
For this reason, supply equipment is controlled as 12 defrostings of first heat exchanger.More particularly, 4 logical valves 14 are controlled as high temperature first cold-producing medium from 11 dischargings of first compressor are directed to first heat exchanger 11.In this way, through being directed to first heat exchanger 11 from high temperature first cold-producing medium of first compressor, 11 dischargings, the heat of first cold-producing medium capable of using is to 12 defrostings of first heat exchanger.
In the process that superincumbent defrosting is handled, if surpass predetermined temperature from the temperature of the water of outside watering 30 supplies, then first cold-producing medium through first heat exchanger 12 can be passed to second heat exchanger 12.In this way, first cold-producing medium can absorb heat above the water of predetermined temperature from temperature, thereby distributes more heats to first heat exchanger 12, realizes the defrosting of first heat exchanger 12 is accomplished fast.In addition, as noted earlier, because the temperature of water surpasses predetermined temperature, so though the heat of water is absorbed by first cold-producing medium, water can not freeze.
On the other hand, if be lower than predetermined temperature from the temperature of the water of outside watering 30 supplies, then when the heat of first cold-producing medium absorption water, water can freeze, and causes the damage of water pipe.For this reason, when the temperature from the water of outside watering 30 supplies was lower than predetermined temperature, first cold-producing medium through first heat exchanger 12 was passed to the 3rd heat exchanger 23, to carry out heat exchange with second cold-producing medium.In this case, because the temperature of second cold-producing medium possibly not be high especially, so first cold-producing medium can absorb a spot of heat from water.Therefore, compare, with first cold-producing medium first heat exchanger 12 is defrosted in the said circumstances and will spend the relative longer time with the situation that from water, absorbs heat when first cold-producing medium.In any case,, damage so can prevent antipriming pipe because first cold-producing medium can not influence the temperature of water.
As stated, according to the supply equipment of embodiment optionally first temperature hot water, have hot water and/or the cold water of comparing the second quite high temperature with first temperature.At this moment, whether producing the hot water of hot water or second temperature of first temperature can be based on the external temperature of outdoor unit 10, from the temperature of the water of outside watering 30 supplies and the temperature that is discharged into the water of water consumption unit 40.
In an embodiment, outdoor unit 10 forms independent unit with overlapping unit 20 and is connected to each other through refrigerant pipe.Yet embodiment is not limited thereto.Selectively; As shown in Figure 4, as embodiment, outdoor unit 10 can comprise second compressor 21, second heat exchanger 22 that is included in the overlapping unit 20; The 3rd heat exchanger 23, the 4th heat exchanger 24, and first, second and the 3rd expansion valve 25,26 and 27.
In an embodiment, 4 logical valves 14 are arranged on the waste side of first compressor 11, can optionally produce hot water or to produce cold water.Yet embodiment is not limited thereto.Selectively, 4 logical valves 14 can be exempted, thus the generation that can omit cold water.
