Abstract
Provided is an instant-heating heat recovery heat pump water heater for bathrooms. By absorbing heat in bathing wastewater, the instant-heating heat recovery heat pump water heater heats tap water for twice. The instant-heating heat recovery heat pump water heater recovers heat through water-water heat exchange for the first time and further absorbs heat from the wastewater through the reverse carnot cycle principle for the second time. Due to the fact that the first heat exchange has no waste work, the total energy efficiency of the instant-heating heat recovery heat pump water heater is far higher than that of the known water source heat pump. The heat pump water heater is in an instant-heating design, so that hot water comes out directly after the tap water enters the heat pump water heater, a water tank is not needed, and space is greatly saved. The heat pump water heater utilizes the wastewater to serve as a heat source, the defrosting problem of an air source heat pump is solved, and energy efficiency and reliability are greatly improved.
Description
Affiliated technical field is a kind of take domestic shower waste water as thermal source, improves the running water temperature by the heat that reclaims shower waste, for the heat-pump hot-water unit of bathing use.
Background technology is along with the energy scarcity problem becomes increasingly conspicuous and the continuous deterioration of environment, energy-saving and emission-reduction have become a vital task of China's development, air energy heat pump water heater as the 5th generation water heater, its efficiency is considerably beyond traditional electric heater and gas heater, won consumers in general's approval, yet air-source water heater also has some intrinsic shortcomings: it is larger that 1, main frame and water tank take up an area the space, and in today of high housing price, increasing user does not admit this; 2, efficiency is subjected to the impact of environment temperature large, because air-source water heater is to absorb heat from air, along with the continuous reduction of air themperature, the absorbable heat of unit reduces thereupon; 3, during winter fin frosting, heat exchange efficiency is low, and defrost will affect the stability of water temperature and the reliability of main frame frequently.
Summary of the invention: the present invention adopts Instant heating type design, solves the problem that air energy heat pump water heater takes up room by the cancellation water tank, by absorb heat from waste water, has solved the problem that absorbs the large and easy frosting of heat temperature influence from air.
The present invention solves the employed technical scheme of its technical problem:
1, adopts contrary Carnot cycle principle, from waste water, absorb heat, reject heat in the running water, the temperature of running water is raise;
2, adopt the backheat design, make running water and waste water carry out primary heat exchange;
3, adopt double pipe heat exchanger as condenser, in condenser, cold-producing medium is with the heat transferred running water, and the running water temperature raises, for bathing.This double-tube heat exchanger long flow path can make water temperature rise to 45 ℃;
4, adopt double pipe heat exchanger as evaporimeter, in evaporimeter, cold-producing medium absorbs heat from waste water.This evaporimeter can make wastewater temperature be reduced to 6 ℃;
5, adopt capillary as throttle mechanism;
6, economizer and evaporimeter are secretly placed the below on chassis, bathroom, enter sewer after making wastewater streams after the bathing cross economizer and evaporimeter;
7, adopt microcomputer control system, by detecting coolant-temperature gage control discharge, make leaving water temperature remain on design temperature constant.
Benefit of the present invention is: adopt the heat pump principle hot water preparing, and adopt water-hydrothermal exchange when elementary heat exchange, the electric heater that its total Energy Efficiency Ratio is relatively traditional, gas heater and air-source water heater all improve greatly; Take Instant heating type design, can produce fast bath water; Because the temperature of bath wastewater is comparatively stable, so the operating condition of complete machine is comparatively stable, influenced by ambient temperature very little; The present invention has saved installing space greatly without storage tank; Adopt water as thermal source, do not relate to the defrost problem, greatly improved the Performance And Reliability of unit.
The present invention is further described below in conjunction with accompanying drawing for description of drawings.
Accompanying drawing is systematic schematic diagram of the present invention
Among the figure 1, double-pipe condenser 2, shower room 3, compressor 4, sleeve pipe economizer 5, casing tube evaporator 6, bathroom drain mouth 7, people 8, capillary 9, tap
Instant heating type recovery type heat bathroom heat-pump water heater in the specific embodiment accompanying drawing, this system mainly is comprised of water system and refrigerant system two parts:
Water system: running water is in sleeve pipe economizer 4, carried out preheating by the spent hot water, temperature tentatively raises, running water after being preheated enters double-pipe condenser 1, absorb heat in the cold-producing medium that from double-pipe condenser 1, flows, temperature is elevated to and can for the temperature of bathing, flows out the bathing for the user by tap 9, in the process of user's bathing, hot water flows down from human body, become waste water, temperature decreases, but still remains on higher temperature, this part waste water is through the discharge outlet 6 in bathroom 2, be discharged to that sleeve pipe economizer 4 is interior to carry out heat exchange with running water, out wastewater temperature further reduces in the sleeve pipe economizer 4, enters casing tube evaporator 5, carry out heat exchange at casing tube evaporator 5 interior water with cold-producing medium, reject heat in the cold-producing medium, water temperature reduces again, drains finally by pipeline.
Refrigerant system: refrigerant system is mainly by compressor 3, double-pipe condenser 1, casing tube evaporator 5, capillary 8 four parts form, the refrigerant gas of low-temp low-pressure, through behind the compressor 3, become the refrigerant gas of HTHP, cold-producing medium flows into double-pipe condenser 1, in double-pipe condenser 1, cold-producing medium rejects heat in the water, cold-producing medium becomes saturated liquid and then becomes subcooled liquid, after subcooled liquid process capillary 8 throttlings of high pressure, the liquid with flash steam that becomes low-temp low-pressure flows into casing tube evaporator 5, in casing tube evaporator 5, cold-producing medium absorbs heat from waste water, become to continue to absorb heat behind the saturated gas and become overheated gas, gets back to compressor 3.
Claims (6)
1. this Teat pump boiler absorbs heat fully from waste water.
2. this Teat pump boiler is provided with sleeve pipe economizer 4, double-pipe condenser 1,5 three heat exchangers of casing tube evaporator.
3. adopt Instant heating type design, running water through directly become behind the main frame can bathing hot water.
4. this Teat pump boiler is not with water tank.
5. employing two-step heating, the first order makes and carries out heat exchange between running water and the spent hot water by economizer 4, and contrary Carnot cycle is adopted in the second level, extracts heat by casing tube evaporator 5 from waste water, by double-pipe condenser 1 heat release in the running water.
6. this Teat pump boiler adopts running water natural pressure and gravity to circulate, and need not water pump.
