The embodiment explanation
1,2 pair of structure of the present utility model specifies in conjunction with the accompanying drawings:
The residential central air conditioning electrical auxiliary heater, it is a kind of metal shell 1 of horizontal column type.Above shell body 1, be provided with water inlet 15 and delivery port 16, at bottom mounting seat 18 and blowoff valve 14.In housing 1, be provided with metal inner tube 2, be provided with heat-insulation layer 3 between shell body 1 and the inner bag 2, be filled with insulation material in this heat-insulation layer 3.Insulation material is an aluminum silicate insulation material.Be welded with diaphragm 17 at the middle part of inner bag 2, the bottom of the lower end of diaphragm 17 and inner bag 2 is provided with passage.Be provided with many U type electric heating tubes 5 in inner bag 2, electric heating tube 5 is fixed on the flange 6 of housing and has lead to link to each other with power supply.Be placed with sensor sleeve 4 in the centre of electric heating tube 5, be provided with temperature sensor 8 and overtemperature prote device 11 in the sensor sleeve 4, electric heating tube 5 and sensor sleeve 4 are all in the same side.Shell flange 6 is provided with metallic safety protection cover 7, is provided with fiberglass waterproof insulation cover 12 in metallic safety protection cover 7, and fiberglass waterproof insulation cover 12 is made by fiberglass waterproof insulation material.In fiberglass waterproof insulation cover 12, be provided with electric heating tube fixed terminal, sensor sleeve 4 fixed terminals and binding post and fairlead.Binding post is connected with thermostat by lead with overtemperature prote device 11 with temperature sensor 8.Between water inlet above the housing 1 15 and delivery port 16, be provided with safety relief valve 13.
These family expenses central air-conditioning electrical auxiliary heater is installed on the residential central air conditioning heat pump backwater road when using.The unit of existing residential central air conditioning heat pump 19, it is to utilize mechanical energy absorbing Lowlevel thermal energy conversion high level heat that recirculated water is carried out heat temperature raising.Hot water is by flowing to indoor user main frame 26 then to the residential customer heat supply through a filter 21 and thermometer 22 in the middle of the hose connector 20.Recirculation water flow in the residential central air conditioning electrical auxiliary heater 24 of the present utility model from indoor user main frame 26 again.When outdoor temperature is lower than below 5 ℃, the also corresponding low temperature of return water temperature that enters from water inlet 15, the temperature that setting is entered the recirculation water of central air-conditioning unit can not reach the operate as normal value, this recirculation water is through the temperature of sensing backwater of temperature sensor 8 thus, will start power supply automatically, to electric heating tube 5 heating and carry out work, thereby the temperature that is transported to the recirculation water of central air conditioner system improves, the heat pump of central air-conditioning unit keeps normal operating conditions, satisfies the heat demand of dwelling house.
Be welded with diaphragm 17 at the middle part of electric heater inner bag 2.This diaphragm 17 can be divided into electrical heating inner bag 2 two relatively independent tempering rooms 27,28.Like this, recirculation water enters first diversed dividing plate 17 in tempering room 27 backs every living from water inlet 15, the recirculation water electric heating tube 5 of will flowing through downwards heats, recirculation water after being heated flows to second tempering room 28 by the passage of bottom diaphragm, carry out post bake through electric heating tube 5 again, can enter into the water return pipeline of central air-conditioning machine set system from delivery port 16.Thus, being provided with of diaphragm 17 can avoid recirculation water when water inlet 15 enters auxiliary heater 24, without electric heating tube 4 heating, directly flows out from delivery port 16.Just can enter the residential central air conditioning unit when having only the delivery port 16 that passes through electrical auxiliary heater 24 to reach the requirement temperature value, guarantee the operate as normal of central air conditioner system, guarantee that recirculation water circulates normally, satisfy the heat supply needs of residential customer.
When family expenses central air-conditioning electrical auxiliary heater 24 work, when return water temperature reaches requirement or after reaching requirement after the heating, temperature sensor 8 and binding post 10 will be controlled, the stop work of electric heating tube 5.Owing to be filled with insulation material in the heat-insulation layer between electrical auxiliary heater shell and the inner bag, have insulating power, what water temperature did not change flows out from delivery port 16 again.In fact, this electrical auxiliary heater 24 just becomes a recirculation water pipeline again.
Be provided with safety protection function at family expenses central air-conditioning electrical auxiliary heater 24.In case system down or people are maloperation, make to enter residential central air conditioning electrical auxiliary heater moment generation high temperature, the steam of high pressure will be destroyed the system of central air-conditioning, the generation of accident.Owing to above these family expenses central air-conditioning electrical auxiliary heater 24, be provided with safety relief valve 13, when electrical auxiliary heater 24 internal pressures surpass the safety value of setting, safety relief valve 13 will be opened pedestal automatically and reveal, release pressure, make residential central air conditioning electrical auxiliary heater 24 internal pressures be no more than safety value, guarantee operate as normal.
As from the foregoing, electrical auxiliary heater of the present utility model is mounted on the backwater road of household central air conditioning system.When outdoor temperature was very low, this electrical auxiliary heater was started working, and improved the recirculation water temperature, guaranteed the operate as normal of residential central air conditioning unit, satisfied the heat demand of dwelling house inside.This device is provided with safety guard, in case the system down of preventing or people avoid the generation of accident for maloperation produces the high temperature high-temperature vapor.This device is provided with automatic temperature control equipment simultaneously, can realize automatic temperature-control.
