The innovative point of the present invention mainly has：
1, the described mode changes in temperature hot water three-way set of preposition water- to-water heat exchanger four, on the basis of the refrigerant loop of general cooling and heating air conditioner, a water- to-water heat exchanger is added between exhaust outlet of compressor and four-way valve air inlet, again using high-pressure gas-liquid separator the refrigerant progress gas-liquid separation by water- to-water heat exchanger, and allow liquid refrigerant directly to go throttling, gas refrigerant is allowed to go the design of throttling again by the condensed liquid of wind heat exchanger again, for whole system, four kinds of function operational modals can be organized, and control system is very simple, no matter which kind of state four-way valve is in, just can be with water heating as long as starting water circulating pump, the function of air conditioner can just be returned by stopping water circulating pump.
2nd, triangle No. four flow controller being made up of three throttling elements of throttling element first, second and third and three check valves of check valve first, second and third of the described mode changes in temperature hot water three-way set of preposition water- to-water heat exchanger four, or Y-shaped No. four flow controller being made up of three throttling elements of throttling element first, second and third and two check valve sequence numbers 1,2 check valves, there is orientation throttling, throttling is distinguished according to demand, throttling and automatic four features to gas occluding are automatically adjusted to heating water condition；The flow controller has the throttling of four tunnels：When heating gas mode, it is considered to which winter makes outdoor temperature is low, for the height pressure difference that guarantee refrigerant is larger, throttling degree is big, so make use of the superposition of first and second throttling element to throttle；During gas mode of freezing, used in summer, the refrigerant condensing temperature of the refrigerant evaporating temperature of indoor wind heat exchanger and outdoor wind heat exchanger is more or less the same, it is small that section mobility ratio heats gas mode, so avoiding first throttle part using the bypass of the first check valve, the throttling of the second throttling element only make use of；Water heating mode, commonly use throughout the year, ambient air temperature changes big, water heating summer, mobility time should not be big, season in spring and autumn mobility slightly increases, winter environment temperature it is low, it is necessary to throttling degree it is maximum, therefore the 3rd throttling element must use heating power expansion valve or electric expansion valve, and throttling degree can be automatically adjusted according to operating mode；Because throttling element plays the role of to control flow to liquid, so throttling element is exactly blocking effect to gas in same pressure differential, this just stops in water circulating pump, water- to-water heat exchanger do not have current by when, force that the exhaust of compressor must flow to indoor wind heat exchanger or outdoor wind heat exchanger goes heat release to condense, again by flow controller, outdoor wind heat exchanger or indoor wind heat exchanger heat absorption evaporation are flowed to, then flow back to compressor；With the three-way set of this principle design, the control valve of refrigerant loop is considerably less, substantially increases operational reliability.
3rd, Y-shaped No. four flow controller being made up of three throttling elements of throttling element first, second and third and two check valve sequence numbers 1,2 check valves of the described mode changes in temperature hot water three-way set of preposition water- to-water heat exchanger four, also there is the function of similar triangle No. four flow controller.
4th, high-pressure gas-liquid separator is utilized, refrigerant liquid and the gas separation come from water- to-water heat exchanger, gas is connected with four-way valve, it is ensured that four-way valve, which is in gas return path, to work, and will not have small leakage to cause to produce systematic function big influence because of four-way valve.
5th, the described mode changes in temperature hot water three-way set of preposition water- to-water heat exchanger four, different modalities operation in, particularly water heating mode when, will not produce refrigerant liquid rest on certain air cooling heat exchanger and make operating loop occur lack refrigerant amount phenomenon；For example, when heating water condition, the coil pipe of the indoor wind heat exchanger of high pressure or outdoor wind heat exchanger is mainly gas and is full of, the liquid of its original storage can participate in the liquid of demand in circulation, the coil pipe of supplementary feed heat exchanger, and this is cleverly to design very much；Therefore, the three-way set refrigeration dosage of this structure is easy to optimization, and refrigerant amount can be automatically adjusted during four kinds of methods of operation, stable.
6th, unit defrosting of the present invention is using the heat of heat storage water tank hot water, and defrosting heat abundance, therefore, it is possible to defrost in a short time thoroughly, ensure that the preposition mode changes in temperature hot water three-way set winter of water- to-water heat exchanger four is normally run.
In summary, advance, the innovation and practicality of the mode changes in temperature hot water three-way set of preposition water- to-water heat exchanger four of the invention are obvious.
