Description
The utility model belongs to the refrigeration and air-conditioning technical field, relates to a kind of air-cooled heat pump device that can make the domestic hot-water.
The air-cooled heat pump device is the heat power equipment that hot and cold water is provided for air-conditioning system, heat pump assembly carries out heat exchange by cold-producing medium and conditioned water, the hot and cold water of producing is sent into the end-equipment of air-conditioning system by water circulating pump, idle call water and air in the end-equipment carries out heat exchange, provide cold and hot amount to the room, thus environmental amenity in the holding chamber.
The structure of existing air-cooled heat pump device as shown in Figure 1, wherein 1 is compressor, 2 is cross valve, 3 is air cooling heat exchanger, 4 is bivalve mechanism, 5 is high pressure receiver, 6 is two-way device for drying and filtering, 7 is water-side heat, 8 is gas-liquid separator, 9 is water circulating pump.This heat pump assembly is when summer cooling moves, and cold-producing medium is indirectly from the room draw heat, and this heat is disposed in the atmospheric environment by air cooling heat exchanger 3; During heating operation, cold-producing medium is draw heat from atmospheric environment, and rejects heat in the indoor environment by conditioned water in the winter time.
When refrigeration, the heat extraction of cold-producing medium all directly is disposed to the atmospheric environment from air cooling heat exchanger, causes the loss of utilisable energy; When heating, exhaust outlet of compressor to the blast pipe between the water-side heat inlet also can cause the certain energy loss.Improve energy utilization rate for reducing energy loss, the existing at present technical scheme of utilizing above-mentioned off-energy, as the patent No. is 92110270, name is called the patent of " refrigerating heat pump hot water apparatus ", the patent No. is 97237016, name is called the patent of " pump type heat safety water heater ", the patent No. is 98204410, name is called the patent of " heat pump water heater ", the patent No. is 98241433, the patent and the patent No. that name is called " water-cooled split room air conditioner " are 00209342, and name is called the patent of " a kind of water-cooled household air conditioning device ".Though above scheme is not quite similar in form, all be to replace air cooling heat exchanger in itself with water cooling heat exchanger, the condensation heat that is discharged when heat pump assembly is freezed is stored by aqueous medium in condenser, thereby provides the domestic hot-water for the user.Taiwan Univ.'s machinery is the Teat pump boiler of professor's Huang Bingjun design, when heat pump assembly freezes, is that the heat that will take out from the room enters the tank equally, uses thereby make hot water; When not needing to freeze, heat pump will be designed to from the atmosphere draw heat, and the heat of discharge still imports and makes hot water in the tank, at this moment, can be described as " solar heat-pump water heater ".Proposition utilizes the solid-liquid phase change material accumulation of heat of heat extraction in heat storage tank of compressor exhaust pipe in the research paper that the rugged good letter in Japanese Sharp company mountain is delivered on " freezing " " 1992; 67 (722): 14-22 " (" Xu Re Ji Intraoperative と つ ア ジ イ system Yu Ji Intraoperative The Should with レ Le one system ユ ア コ ソ "), evaporation thermal source during as the heat pump assembly defrosting, during defrosting from heat storage tank heat-obtaining, developed the defrosting formula heat pump of indoor continuous heat supply, thus the room temperature that the reverse work of system causes when having reduced because of heat pump to melt frost fluctuation.
Above-mentioned prior art problems is, make the heat in the compressor air-discharging obtain utilizing, will carry out big change to existing heat pump refrigerating device, or existing air cooling heat exchanger changed into water cooling heat exchanger, or an accumulation of heat tank will be set, with the heat that receives heat pump from the room, to take out, therefore, the structure of these schemes is more complicated all, is difficult for implementing.
The purpose of this utility model is to improve the deficiencies in the prior art, provide a kind of and can utilize compressor air-discharging heat manufacturing domestic hot-water, again not to the condenser in the existing heat pump improve, simple air-cooled heat pump device.
For achieving the above object, the utility model is taked following design:
This air-cooled heat pump device includes compressor, cross valve, air cooling heat exchanger, bivalve mechanism, high pressure receiver, two-way device for drying and filtering, water-side heat, gas-liquid separator and water circulating pump, it connects and composes the air-cooled heat pump device, between the inlet of the exhaust outlet of described compressor and described cross valve, a hot water heat exchanger is set, described hot water heat exchanger is a dividing wall type heat exchanger, partition is separated out two adjacent isolated mutually spaces: refrigerant flow path and aqueous medium runner, the blast pipe of described compressor is connected with the inlet of the refrigerant flow path of described hot water heat exchanger, the outlet of refrigerant flow path is connected with the inlet of described cross valve, the import of described aqueous medium runner can be connected with water supply pipe, its outlet can use equipment such as shower nozzle with hot water, the tap of dish of washing one's hands connects, and described hot water heat exchanger preferably has heat-insulation layer.
In use, the aqueous medium in the aqueous medium runner and the cold-producing medium in the refrigerant flow path carry out heat exchange by partition therebetween, absorb the part sensible heat of compressor air-discharging, make the water temperature raising, thereby provide the domestic hot-water for the user.
The air-cooled heat pump apparatus structure that the utility model provides is simple, only between the exhaust outlet of the compressor of original common air-cooled heat pump device and cross valve inlet, set up a hot water heat exchanger with heat-insulation layer, the condenser of existing heat pump does not change, and existing equipment is not had bigger change.No matter this heat pump still is in other season in summer, winter, as long as be in running status, just can be simultaneously for the user provide the domestic hot-water, and in this course, it has reasonably utilized the partial condensation heat of hot water heat exchanger, thereby has improved energy utilization rate; Simultaneously, owing to increased the condensation area of device, also reduced the condensation temperature of device, so improved the Energy Efficiency Ratio of system.
The utility model is described in further detail below in conjunction with accompanying drawing.
