Adopt the present invention, can select mode of operation suitable in the above-mentioned pattern, reach the change energy demand that satisfies every day according to the water temperature situation in height peak energy source demand and the accumulation of energy water tank.For example: when being in summer, needing refrigeration and heat water, can first running refrigerating hot water pattern, evaporation side heat absorption like this, condensation side heat release, the efficiency of unit can reach more than 6, and good energy savings has been saved the operating cost of product.Also demand is freezed after hot water makes, and so just can select the separate refrigeration pattern, freezes, and satisfies the demand of refrigeration.But also have the part-time refrigeration requirement lower in one day, the refrigerating capacity of unit is greater than the cold of actual demand, and unit will be shut down; but accumulating type air conditioner cold and hot water machine does not need to shut down; continuation is freezed to the accumulation of energy water tank, stores the part cold, the demand so that group peak cold to be provided.When the water temperature in the accumulation of energy water tank because provide cold and temperature is elevated to 20 degree when above to indoor apparatus of air conditioner, can not directly provide cold to indoor apparatus of air conditioner this moment, switch the flow direction of refrigerant like this with regard to demand, the accumulation of energy water in water tank is carried out degree of depth utilization, because at this moment the water temperature in the water tank is still low than ambient temperature, the refrigerating capacity of unit can improve, and power consumption can reduce, and reaches to improve refrigeration, energy savings and operating cost.
When being in the spring and autumn transition season, also need to use air-conditioning to freeze and warm oneself this moment, at this moment can select to heat aqueous mode separately, produces the domestic hot-water, do not need to add the equipment of producing the domestic hot-water, reach the buying expenses purpose that reduces used device.
Need heat winter water and when heating when being in, ebb heats the stage during demand, selects independent heating mode operation, when satisfying the heating demand, change over to and heat water running separately, hot water also heat finish after, the accumulation of energy mode operation is saved heat to the accumulation of energy water tank.Heat the stage during demand when being in the peak, carry out accumulation of heat and utilize mode operation, satisfy the demand of peak heating.Shift utilization by putting aside good energy, the energy requirement that freezes, heats when reaching the height peak valley reaches simultaneously and improves refrigeration and heating capacity, improves the efficiency of unit.Cooperate the accumulation of energy of accumulation of energy water tank, solve, have bigger feasibility, meet the environmental protection policy of country, have bigger economic benefit and social benefit for the big regional changes in temperature problem of day and night temperature.
