The preposition water- to-water heat exchanger changes in temperature hot water three-way set of the single-unit stream, it is characterized in that: the water of the water- to-water heat exchanger is logical Road connects on circulating water loop or is also equipped with respectively water route electricity with the circulating water outlet of heat storage water tank, import into and out of interface Magnet valve, when executing four kinds of function methods of operation, the control mode of waterway electromagnetic valve is identical as the control mode of water circulating pump.
Innovative point of the invention mainly has:
1, the preposition water- to-water heat exchanger changes in temperature hot water three-way set of the single-unit stream, in the refrigerant circuit of general cooling and heating air conditioner On the basis of, a water- to-water heat exchanger is added between exhaust outlet of compressor and four-way valve air inlet, and high-pressure gas-liquid is utilized to separate Device and allows liquid refrigerant directly to go to throttle gas-liquid separation is carried out by the refrigerant of water- to-water heat exchanger, allows gas refrigerant The design for going throttling again by the condensed liquid of wind heat exchanger again can organize four kinds of function operation moulds for whole system State, and control system is very simple, no matter which kind of state four-way valve is in, as long as starting water circulating pump water heating, stops Only water circulating pump can return the function of air conditioner.
2, the preposition water- to-water heat exchanger changes in temperature hot water three-way set of the single-unit stream by a throttling element and four check valves, group At to four operational modals: water heating, refrigeration gas and water heating, heating gas and refrigeration gas, difference adjusts throttling according to demand The characteristics of;
3, there is the very big pressure loss liquid flow is out-of-date due to flow controller, so the flow controller in same pressure difference It is exactly blocking effect to gas, this just stops in water circulating pump, when water- to-water heat exchanger does not have water flow to pass through, forces the exhaust of compressor Indoor wind heat exchanger must be flowed to or outdoor wind heat exchanger is gone, since indoor fan or outdoor fan operate, refrigerant heat release is solidifying Form liquid, fluid density is bigger than gas, and gas condensation process just constantly aspirates the refrigerant gas of high-pressure gas-liquid separator, coagulates The liquid refrigerant of knot, indoors, the inlet of the left end liquid inlet and outlet connectors of outdoor wind heat exchanger to high-pressure gas-liquid separator Between pipeline on the pressure that generates of liquid be greater than the right end gas inlet and outlet connectors of indoor and outdoor wind heat exchanger to high-pressure gas-liquid point From the pressure that gas on the pipeline between the gas outlet of device generates, so the refrigerant liquid cognition of condensation flows into high-pressure gas-liquid point again From device, and the liquid outlet from its bottom, after being depressured by flow controller, outdoor wind heat exchanger or indoor wind heat exchanger are flowed to, then inhale Thermal evaporation, then flow back to compressor;The three-way set designed with this principle, the control valve of refrigerant circuit is considerably less, mentions significantly High operational reliability.
3, the gas outlet of the high-pressure gas-liquid separator is connect with four-way valve intake interface, and no matter whether water- to-water heat exchanger exchanges heat Water heating, the refrigerant for flowing into high-pressure gas-liquid separator is liquid or gas, can guarantee that four-way valve is in work in gas return path Make, avoid four-way valve when passing through liquid, because of the minute leakage of four-way valve, highly pressurised liquid is directly leaked into low pressure gas and returned Road is gone, and just will be greatly reduced the efficiency of system.
4, the preposition water- to-water heat exchanger changes in temperature hot water three-way set of the single-unit stream especially heats in different modalities operation When water mode, refrigerant liquid will not be generated and rest on certain air cooling heat exchanger and operating loop is made to occur lacking showing for refrigeration dose As;Because of structure of the invention, when heating water condition, the coil pipe of the interior wind heat exchanger of high pressure or outdoor wind heat exchanger is mainly Gas is full of, and liquid originally can gradually participate in recycling, and the liquid of demand in the coil pipe of supplementary feed heat exchanger, this is very It cleverly designs, i.e., for the heat pump refrigerant refrigeration dose of this structure convenient for optimization, refrigeration dose is constant when operation, stable.
5, unit defrosting of the present invention utilizes the heat of heat storage water tank hot water, and defrosting heat is sufficient, therefore can be in the short time Interior defrosting thoroughly, can guarantee that single-unit stream preposition water- to-water heat exchanger changes in temperature hot water three-way set winter operates normally.
In conclusion advance, novelty and the reality of the preposition water- to-water heat exchanger changes in temperature hot water three-way set of single-unit stream of the invention It is obvious with property.

The refrigerant flow circuit of heating gas mode is: compressor → water- to-water heat exchanger → high-pressure gas-liquid separator → four-way valve air inlet To left interface → interior wind heat exchanger → third check valve → high-pressure gas-liquid separator → flow controller → second one-way valve → outdoor The right interface of wind heat exchanger → four-way valve is to middle interface → low-pressure gas-liquid separator → compressor;Its control is compressor, interior It is operated with outdoor fan, four-way valve is in heat pump cycle state, and water circulating pump is shut down;Refrigerant in water- to-water heat exchanger without heat exchange, It absorbs heat and evaporates in outdoor wind heat exchanger, wind heat exchanger heat release indoors heats gas;
The refrigerant flow circuit of refrigeration gas mode is: compressor → water- to-water heat exchanger → high-pressure gas-liquid separator → four-way valve air inlet To right interface → outdoor wind heat exchanger → four check valves → high-pressure gas-liquid separator → flow controller → the first check valve → interior For the left interface of wind heat exchanger → four-way valve to middle interface → low-pressure gas-liquid separator → compressor, control is compressor, interior It is operated with outdoor fan, four-way valve is in refrigeration cycle state, and water circulating pump is shut down;Refrigerant in water- to-water heat exchanger without heat exchange, In outdoor wind heat exchanger exothermic condensation, wind heat exchanger absorption refrigeration gas indoors.
5. the preposition water- to-water heat exchanger changes in temperature hot water three-way set of single-unit stream according to claim 4, it is characterized in that: the water changes The water passage of hot device is connected on circulating water loop respectively with the circulating water outlet of heat storage water tank, import into and out of interface and is equipped with Waterway electromagnetic valve, the control mode and the control mode phase of water circulating pump of waterway electromagnetic valve when executing four kinds of function methods of operation Together.
