Description
Affiliated technical field
The utility model relates to heat-pump hot-water and air-conditioning system, and especially a kind of highly effective energy-saving heat pump air conditioner able to heat water belongs to the heat pump application technical field.
Background technology
Existing heat pump air conditioner function singleness, generally can only be used to regulate air performance parameter and its in summer during refrigeration work to outdoor discharging hot gas, both wasted a large amount of heat energy, and influenced external environment again and caused the tropical island effect in city, its refrigerating efficiency is lower in addition; Teat pump boiler has thermal efficiency height, energy-conservation, excellent properties such as safety and environmental protection, as energy-saving and cost-reducing hot water facility of new generation, be familiar with by people gradually and promote the use of, but, a large amount of refrigerating capacities that the Teat pump boiler of prior art produced when working its summer often are difficult for being utilized, operation principle is: the cold-producing medium that cold-producing medium is compressed into HTHP by compressor enters into behind the water condenser cold-producing medium that is absorbed heat by water and be condensed into medium temperature and medium pressure, inflow evaporator absorbs heat energy after throttling arrangement reduces pressure into the cold-producing medium of low-temp low-pressure then, gets back to compressor at last and finishes circulation.When the water temperature in the water condenser is lower or higher, it is low excessively to be easy to generate system refrigerant back pressure low pressure, the return-air recirculating oil quantity is very few or the pressure at expulsion high pressure is too high, condensation temperature is too high, cold-producing medium evaporation heat absorption capacity is crossed problems such as low, to such an extent as to had a strong impact on the performance of the normal performance of heat-pump water heater, and the life-span of compressor is subjected to greatly decaying, therefore, though its advantage of heat-pump water heater is a lot, but, because it also has above-mentioned fatal shortcoming, its practical effect and actual life can not be fully satisfactory, its structure more complicated in actual design is made, join the type difficulty, this has also limited applying of the energy saving and environment friendly product of this a new generation widely.In sum, the air-conditioner of prior art relative with the Teat pump boiler function single, performance is not ideal enough, needs repeated configuration two cover heat pump assemblies when people not only need air-conditioning but also need hot water, increases customer investment cost and energy use cost exponentially.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of highly effective energy-saving heat pump air conditioner able to heat water.
The purpose of this utility model is achieved in that the highly effective energy-saving heat pump air conditioner able to heat water, mainly contain compressor, sluice valve, water condenser, indoor heat exchanger, throttling arrangement, outdoor heat exchanger and reversing arrangement constitute, and connect into the cold-producing medium closed circulation system by corresponding coolant channel, this system is by electric control gear control work, it is characterized in that the water condenser refrigerant outlet in the above-mentioned cold-producing medium closed circulation system is divided into two-way at least by corresponding coolant channel, wherein have at least and lead up to corresponding coolant channel and link to each other, have at least another road behind the serial connection strobe unit, to link to each other with reversing arrangement high-pressure refrigerant inlet by corresponding coolant channel with throttling arrangement.
The heat pump air conditioner of the utility model and prior art and Teat pump boiler are compared and have been obtained appreciable performance boost and good effect:
Under the gating control of sluice valve, water condenser can add hot water for answering the domestic hot-water, indoor heat exchanger can be supplied air conditioner refrigerating or heat, reached the effect of air conditioning and hot water function dual-use, and air conditioner refrigerating can freely heat water when using, the comprehensive Energy Efficiency Ratio of unit is able to remarkable lifting, has reduced the environment thermal energy discharging simultaneously, has reduced urban heat land effect.
Moreover because the utility model water condenser refrigerant outlet is divided into two-way at least by corresponding coolant channel, the corresponding coolant channel of wherein leading up to links to each other with throttling arrangement, other has one the tunnel to link to each other with reversing arrangement high-pressure refrigerant inlet by corresponding coolant channel after being connected in series a strobe unit, like this, when needed, can so that water condenser under the control of the gating of strobe unit, both can form the duty of relative parallel-connection structure with indoor heat exchanger or outdoor heat exchanger, also can form relative parallel-connection structure and relative cascaded structure simultaneously and the duty of depositing.When strobe unit is disconnected, water condenser and indoor heat exchanger or outdoor heat exchanger form the duty of relative parallel-connection structure, at this moment, the flow of refrigerant stroke is shorter relatively, can guarantee that the utility model is when hot water is worked, the cold-producing medium total amount is abundant, hot water speed is fast, the unlikely return-air recirculating oil quantity of system is very few, back pressure is low excessively, return-air and excessive discharge temperature, when especially lower and/or outdoor heat exchanger ambient temperature of living in is low in the water condenser water temperature, can guarantee security of system, stable, work efficiently, and when water condenser is when forming relative parallel-connection structure duty with outdoor heat exchanger under the control of the gating of reversing arrangement, indoor heat exchanger is a system evaporator, can efficiently supply the air conditioner refrigerating in hot day when heating water apace; When strobe unit is connected, water condenser and indoor heat exchanger or outdoor heat exchanger form relative parallel-connection structure and cascaded structure is simultaneously and the duty of depositing relatively, this moment, a part of liquid refrigerant branched to indoor heat exchanger or outdoor heat exchanger through strobe unit, a part or the subcooler or the reservoir of indoor heat exchanger or outdoor heat exchanger double as system condensing device, this moment, cold-producing medium overall flow stroke was longer relatively, can guarantee that the utility model is when hot water is worked, refrigerant amount is suitable, and the unlikely pressure at expulsion of system is too high, condensation temperature is too high, cold-producing medium evaporation heat absorption capacity is low excessively, moreover can also be when heating water the part air-conditioning of efficient provision cold day heat or the air conditioner refrigerating in hot day, improved the utility model complete machine combination property coefficient, when especially higher and/or outdoor heat exchanger ambient temperature of living in is higher in the water condenser water temperature, can guarantee security of system, stable, work efficiently and the life-span of critical piece such as compressor is greatly ensured; Through electric control gear be provided with dexterously can so that in the water condenser water temperature when lower and/or outdoor heat exchanger ambient temperature of living in is low strobe unit disconnect, and when the water condenser water temperature when higher and/or outdoor heat exchanger ambient temperature of living in is higher strobe unit connect, the utility model can be given full play to the advantage performance under its various operating modes like this, reaches optimum efficiency.The utility model is simple for structure at the actual design manufacture view, it is easy to join type, and unit performance is more stable during the work of hot water operating mode, long service life.
