Description
Technical field
The utility model relates to a kind of condensation heat step energy recycle device that is used for multistage hot-water air-conditioning, adopt cycles, economized to improve refrigeration system, adopt the heat exchanger of corresponding construction to bear cold, condensation heat-obtaining, overheated heat-obtaining respectively and produce the boiling water function, the standard matching component of can be used as is advantageously used in the condensation heat of heat pump and produces hot water apparatus, belongs to air-conditioning heat pump and heat supply process apparatus field.
Background technology
Factor affecting such as in the water heater of extensive use at present, the electric heater energy consumption is big, operating cost is too high, and the gas heater safety problem gives prominence to, is subjected to source of the gas to limit, and solar water heater is subjected to sunlight, take up room are excessive.Teat pump boiler adopts compressor refrigeration system to absorb heat from outdoor air, and running water is heated to temperature required with usefulness as the domestic hot-water by the fluorine water-to-water heat exchanger, its power consumption only reaches below 1/4 of electric heater, annual integrated operation expense is far below electric heater, also much lower than gas heater, solar water heater, and energy-conserving and environment-protective, safe and reliable, install and use and easy to maintenance, be fit to popularize in an all-round way, therefore applied fast in recent years.
In existing air source heat pump hot water and the boiler, great majority all will add the condenser that hot water uses and be placed in the hot-water cylinder, the heat exchanger heat transfer ability of this mode of smouldering is very low, cause heat exchanger area very big, and in a single day faults such as relevant portion leakage appear, can cause cold-producing medium to enter in the hot-water cylinder or the refrigeration system water inlet, and maintenance difficult.
Generally produce boiling water and often adopt electrothermal, combustion gas etc., the former directly expends the high-grade electric energy in a large number, the latter has also expended the high-grade primary energy, and the heat energy conversion ratio of general domestic gas cover has only about 20～30% the therefore in fact also very high energy waste of existence.
Emerging in the market heat pump techniques is produced the product of boiling water, system adopt greatly improve pressure at expulsion with obtain surpass 100 ℃ delivery temperature with the boiling water of purchasing, the compression ratio of heat pump cycle is excessive, cause Energy Efficiency Ratio greatly to descend, and heat exchanger area is excessive, make investment of equipment, running cost all comparatively high, be difficult to obtain the expection energy-saving effect, thus in fact far be not can practical application matured product.
Existing Teat pump boiler does not adopt the cycles, economized device basically, because the heating domestic hot-water needs condensation temperature very high to design temperature (generally getting about 50～60 ℃), cause pressure at expulsion very high, compression ratio is excessive, particularly even more serious under the condition in the winter time, this causes Energy Efficiency Ratio EER (heating capacity/input power) to reduce greatly on the one hand and power consumption is increased, and economy worsens, the fault rate of parts such as compressor increases on the other hand, and the life-span reduces.
Summary of the invention
The purpose of this utility model and task are, variety of problems at above-mentioned existence, utilize the state change process and the characteristics thereof of compressor air-discharging condensation heat, take counterflow exchange farthest to utilize the temperature levels of different phase, the heat of corresponding grade is taken out in segmentation, creatively with the synthetic cover standard package of the heat exchanger package of various corresponding construction forms, be conveniently used in small-sized household and medium-sized business air conditioner/heat-pump hot-water and boiler, big-and-middle-sized engineering central air-conditioning hot water unit, satisfy and reclaim the refrigeration unit condensation heat with warm domestic hot-water in providing (45～60 ℃), the needs of multiple hot water such as high temperature accumulation of energy hot water (60～75 ℃) and boiling water, and the employing of cycles, economized device can greatly reduce Compressor Discharge Pressure, improves heating energy efficiency ratio.
For this reason, the utility model has designed a kind of condensation heat step energy recycle device that is used for multistage hot-water air-conditioning, form by one group of fluorine water-to-water heat exchanger, a fluorine fluorine heat exchanger and other accessory, wherein fluorine water-to-water heat exchanger group comprise in boiler, superheater, conventional condenser, the subcooler partly or entirely.The high temperature and high pressure steam that compressor is discharged is successively by boiler, superheater, conventional condenser, subcooler and cycles, economized device, and the low temperature and low pressure steam that comes out with evaporimeter in the cycles, economized device carries out heat exchange, finishes whole condensation and crosses cold process and be sent to the evaporimeter refrigeration after the throttle mechanism step-down.
In hot water circuit, the low temperature water inlet is in the liquid heat of subcooler absorption refrigeration agent, in conventional condenser, absorb two-phase condensation heat and a part of steam superheating amount and liquid heat, after water temperature reaches 45～60 ℃, wherein a part can directly be sent, another part is sent to the heat that superheater absorbs the overheated zone, after water temperature reaches 60～75 ℃, wherein a part can be used as high-temperature-hot-water and stores in hot-water cylinder, another part is sent to the heat that superheater absorbs overheated zone highest temperature part, and water temperature is sent after reaching 95～99 ℃.
Cycles, economized device, subcooler, superheater and boiler all can be realized the step energy utilization of good countercurrent flow with abundant realization condensation heat.Need not to realize high-temperature heat accumulation as the user, can only establish the one-level intake, send after in superheater, hot water being heated to required temperature.Need not the boiling water function as the user, then can not establish special-purpose boiler and only establish the heat that superheater absorbs the overheated zone.
The cycles, economized device adopts external fin coiled or bushing type or board-like fluorine fluorine heat exchanger.Employing cycles, economized device can be when keeping condensation temperature to be lower temperature levels (40～54.4 ℃), be that pressure at expulsion is when being in reduced levels, effective lifting delivery temperature is with maintenance and even improve leaving water temperature level (35～100 ℃ of hot water effluent's temperature ranges) greatly, the simultaneity factor Energy Efficiency Ratio remains on high level, this is that general air-cooled heat pump and air source heat pump hot water, the dual-purpose machine of boiling water are unapproachable, and the reduction of pressure at expulsion can effectively reduce the possibility that each parts such as compressor break down, and prolongs machine life.
The utility model can be used as the standard configuration component application of refrigeration machine condensation and cycles, economized part in heat pump hot-water system, thereby for the machine system structure is optimized improvement, the purpose that realizes energy-efficient reliablely and stablely cooling, heat supply, productive life hot water and boiling water provides splendid equipment to select, make compact integral structure, easy to assembly, cost is low, effectively reduced fault rate, increase the service life, installation, operation, easy to maintenance, region and climate adaptability are wide.
