Description

A kind of shower waste heat recovery and preheating heating arrangement
Technical field
The utility model relates to a kind of shower waste heat recovery and preheating heating arrangement.Belong to machinery manufacturing technology field, be applicable to heating efficiency, energy-saving effect, waste water residual heat organic efficiency, comfort level requires the selection of shower waste heat recovery and preheating heating arrangement in higher electric heater.
Background technology
In order to energy-conservation and water saving, major part family has a bath and all adopts shower, during shower be by cold tap water heating to about 42 DEG C for people, but after shower, the temperature of waste water also has about 35 DEG C, these waste water containing a large amount of heat energy will directly be discharged by sewer, waste very large.If the heat recovery in shower waste can be used for heating tap water, then greatly can reduce the energy ezpenditure of water heater.But in the process of shower; use existing electric heater always to need to wait for a period of time and just have hot water, and often can run into the sometimes cold and sometimes hot situation of water temperature when shower, hot water supply not in time; water resource waste is serious, and water heater " instant-heating " function is weak.Existing water heater also can use heat exchanger tube to carry out heat exchange, thus recycles the waste heat of shower waste, improves the waste water residual heat rate of recovery.But the length of heat exchanger tube is longer, build is comparatively large, is not too applicable to small enclosures room.
Heat pump heating operations is by electrical energy drive compressor, and cold-producing medium is evaporated in evaporimeter, absorbs heat from low-temperature heat source simultaneously, and the electric energy transfer then absorbed heat and compressor consumed within the condenser is to the process of heating target.Heat pump unit is formed primarily of compressor, condenser, evaporimeter and expansion valve four part, and according to inverse Carnot cycle principle, refrigerant runs at unit inner sealing, and with outside, heat exchange occurs by condenser and evaporimeter.Refrigerant completes the boosting temperature-rise period of gaseous state under the effect of compressor, heat of high temperature heating water is discharged after entering condenser, after cooling, temperature declines, through filter, expansion valve, to pressure drop during evaporimeter, liquid evaporation endothermic is rapidly converted into gaseous state again, absorbs heat from waste water simultaneously, refrigerant temperature raises gradually, gets back to the circulation that compressor starts is new.So constantly circulate, the low temperature remnants just achieved in waste water are absorbed by refrigerant, and discharge its heat and heat for the second time of cold water.The benefit adopting compressor to heat to realize the transmission of low-temperature heat quantity to heat of high temperature, and traditional conduction heat transfer pattern can not realize, and heating efficiency can reach about 300-400%, and energy-saving effect is obvious.
In sum, in order to solve hot water supply in prior art, not in time, water resource waste is serious, and water temperature difference is large, weak, the existing heat-exchanger rig of water heater " instant-heating " function uses the problems such as inconvenience, need a kind of water-saving result of invention at present badly, energy-saving effect is remarkable, instant-heating performance is strong, and comfort level is high, saving water resource, practical, even water temperature, the shower waste heat recovery that build is small-sized and preheating heating arrangement.
Utility model content
The utility model proposes a kind of shower waste heat recovery and preheating heating arrangement, in solution prior art, hot water supply not in time, water resource waste is serious, and water temperature difference is large, and weak, the existing heat-exchanger rig of water heater " instant-heating " function uses the problems such as inconvenience.
The technical solution of the utility model is achieved in that
A kind of shower waste heat recovery and preheating heating arrangement, it is characterized in that, described structure comprises waste water collection device, heat pump unit and preheating heater, and described waste water collection device comprises shower waste pond, the first water pump and the first filter; Described preheating heater comprises heater, the second water pump, heat pump unit and one-way cock; Described heat pump unit comprises condenser and evaporimeter; Described preheating heater one end is provided with stop valve and shower nozzle, and described evaporimeter one end is provided with wastewater outlet, is provided with running water water intaking valve and running water water inlet bottom described condenser.
Further, compressor, temperature sensor, expansion valve and filter is provided with between described evaporimeter and condenser, described compressor, temperature sensor, expansion valve and filter form a closed circuit by metal connecting tube, are provided with refrigerant in described closed circuit.
Described metal connecting tube is in spiral shape through evaporimeter and condenser one section.
The utility model has following feature and beneficial effect:
The utility model sets up preheating heater to carry out the initial preheating to cold water, realizes instant-heating.After preheating cold water 30 seconds, can export hot water, subsequently in shower process, the shower waste after washing is by heat pump unit for running water provides heat, and energy-saving effect is strong.Whole device just can realize " self-sufficient " under the driving of heat pump unit.
Refrigerant completes the boosting temperature-rise period of gaseous state under the effect of compressor, heat of high temperature heating water is discharged after entering condenser, after cooling, temperature declines, through filter, expansion valve, to pressure drop during evaporimeter, liquid evaporation endothermic is rapidly converted into gaseous state again, absorbs heat from waste water simultaneously, refrigerant temperature raises gradually, gets back to the circulation that compressor starts is new.So constantly circulate, the heat just achieved in waste water is absorbed by refrigerant, and discharges the heating of its heat for cold water, improves waste water residual heat organic efficiency.
The utility model, by the combination of heat pump unit and preheating heater, allows user without the need to waiting for the very long preheating cold water time, and instant-heating is strong, reaches to want to wash just to wash, want to wash how long just wash result of use how long, and comfort level is high.The feature of instant heating also can prevent bacteria breed in electric heater, reduces secondary pollution.Energy-saving effect is remarkable, saves energy consumption and reaches 94.6%.
