The instant heating type heat recovery hot water system has a simple structure and a small volume and is convenient to install; a mechanical heat pump is formed by the compressor, the evaporator and the condenser; the heat in waste water is recovered by the mechanical heat pump and is transmitted to tap water which is to enter the electric water heater to heat the tap water, so that the water inlet temperature of the electric water heater is risen, the heating power of the electric water heater can be reduced and the power consumption can be reduced, as a result, the purpose of energy conservation is achieved.
Description
Technical field
The utility model belongs to technical field of water heaters, particularly a kind of Instant heating type heat recovery hot-water heating system.
Background technology
At present, electric heater can be divided into storage-type electric water heater and instant electric water heater's two large classes substantially.The defective of storage-type electric water heater has: because volume is large, weight is large, it is many to take the interior space, is difficult for installing; Be subjected to the restriction of volume, output is also limited to; Need in advance preheating, hot water can not be provided at once; The untimely use of hot water can cause heat to scatter and disappear gradually, need repeatedly add the heat waster electric energy.Above-mentioned shortcoming can't overcome, and makes the market sales volume of storage-type electric water heater be year by year downward trend.Defects in view of storage-type electric water heater, people to little, lightweight, the easy installation of volume, need not preheating, can be continuously a large amount of supplying hot waters, the instant electric water heater that can repeatedly not heat relative saves energy given abundant affirmation, instant electric water heater's market sales volume rapidly rises, and the gesture that replaces storage-type electric water heater is arranged greatly.
In order to ensure instant electric water heater's supply water temperature and output, instant electric water heater's design power consumption is all greater than 8Kw or greater than 10 Kw.Although newly-built house has considered that indoor comparision of quantity of electricity is large when finishing, house wiring and the following instant electric water heater of ammeter load 10 Kw do not have problems; But the load capacity of house wiring and ammeter is rare greater than 5kW in the house of finishing in one's early years, and this has just greatly limited the instant electric water heater in the use of fitting up in one's early years in the house.Therefore, people wish that the instant electric water heater reduces energy consumption and power consumption as far as possible under the prerequisite of assure feed water temperature and output.
No matter be storage-type electric water heater or instant electric water heater, its operation principle all is to convert electric energy to heat energy water is heated, the size of water yield, the height of leaving water temperature and power consumption are directly proportional, and purely reduce energy consumption and can't guarantee water yield and leaving water temperature.In addition, the instant electric water heater determines heating power according to discharge, inflow temperature and leaving water temperature.Therefore, when discharge and leaving water temperature are determined, improve the heating power that inflow temperature can reduce water heater as far as possible.Yet the waste water after the at present bathing directly is disposed in the sewer, and the heat in the waste water is thereupon waste also.
The utility model content
The purpose of this utility model has provided a kind of Instant heating type heat recovery hot-water heating system of simple in structure and saves energy.
For achieving the above object, the technical solution of the utility model is: a kind of Instant heating type heat recovery hot-water heating system comprises the compressor, waste water heat exchanger and the preheating cold water device that are interconnected; The waste water heat exchanger comprises the evaporimeter in heat exchange case and the heat exchange case, and heat exchange case top is connected with sewage collecting box by wastewater inlet pipe, and the heat exchange case bottom is provided with waste outlet; The preheating cold water device comprises the condenser in preheating cabinet and the preheating cabinet, and preheating cabinet top is connected with electric heater by upper hose, and the preheating cabinet bottom is provided with the running water water inlet; Electric heater is provided with outlet pipe.
Described outlet pipe oral area is corresponding up and down with sewage collecting box.
Described outlet pipe oral area is provided with shower nozzle, and shower nozzle is corresponding up and down with sewage collecting box.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises compressor, waste water heat exchanger and the preheating cold water device that is interconnected; The waste water heat exchanger comprises the evaporimeter in heat exchange case and the heat exchange case, and heat exchange case top is connected with sewage collecting box by wastewater inlet pipe, and the heat exchange case bottom is provided with waste outlet; The preheating cold water device comprises the condenser in preheating cabinet and the preheating cabinet, and preheating cabinet top is connected with electric heater by upper hose, and the preheating cabinet bottom is provided with the running water water inlet; Electric heater is provided with outlet pipe, it is simple in structure, volume is little, is convenient to install, and compressor, evaporimeter and condenser form the mechanical type heat pump, the mechanical type heat pump is with the heat recovery in the waste water, be transferred to the running water that is about to enter electric heater, with tap water heating, improve the inflow temperature of electric heater, can reduce the heating power of electric heater and reduce power consumption, thereby reach energy-conservation purpose.
2, the outlet pipe oral area is corresponding up and down with sewage collecting box, is convenient to sewage collecting box and collects waste water.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Instant heating type heat recovery hot-water heating system as shown in Figure 1, it comprises compressor 1, waste water heat exchanger and the preheating cold water device that is interconnected, the waste water heat exchanger comprises the evaporimeter 2 in heat exchange case 7 and the heat exchange case 7, be connected with sewage collecting box 6 on heat exchange case 7 tops by wastewater inlet pipe 13, heat exchange case 7 bottoms are provided with waste outlet 10; The preheating cold water device comprises the condenser 3 in preheating cabinet 4 and the preheating cabinet 4, is connected with electric heater 8 on preheating cabinet 4 tops by upper hose 11, and preheating cabinet 4 bottoms are provided with running water water inlet 5.Be provided with outlet pipe 12 at electric heater 8, outlet pipe 12 oral areas are provided with shower nozzle 9, and shower nozzle 9 is corresponding about in the of 6 with sewage collecting box, are convenient to sewage collecting box 6 and collect waste water.
Workflow of the present utility model is: waste water flows in the heat exchange case 7 after being collected by sewage collecting box 6, and waste water institute heat content is absorbed by evaporimeter 2, and the cooling waste water that is absorbed heat is disposed to sewer by waste outlet 10; Absorbing heat in the evaporimeter 2 and the refrigerant that gasifies are added by compressor 1 and are sent to condenser 3, refrigerant flows into evaporimeter 2 emit heat liquefaction in condenser 3 after again, and the heat that refrigerant cooling, liquefaction liberated heat and compressor 1 consume electric energy conversion all is used for the water in the running water preheating cabinet 4 is carried out preheating; Running water after the preheating electric heater 8 of flowing through, 8 pairs of water of electric heater are heated to design temperature again, then flow out through outlet pipe 12.
