The heating water circulation unit is mainly used in heating terminal, for example radiator fin or floor heating coil pipe is delivered in heating of heating water and circulation.It comprises mainly and being used for the exchange heat of the solar energy recirculated water heating water-to-water heat exchanger to heating recirculated water that described heating water-to-water heat exchanger is arranged in the water circulation pipe of described solar energy water cycling element; Be used for heating water is carried out electrically heated heating water power heater.Certainly, in the water circulation pipe therein, comprise that also circulating pump etc. can make the necessary parts of water circulation.The heating water circulation unit is at first by the heat of heating water-to-water heat exchanger collection from solar energy recirculated water, secondly, by the heat of heat pump indoor heat exchanger collection from heat pump unit, only above-mentioned two kinds of shortages of heat with the situation that reaches the heating requirement under, just open heating water power heater heating recirculated water heated.
The chilled water cycling element is mainly used in the refrigeration terminal is delivered in chilled water cooling and circulation, and with regard to water circulation pipe, it and heating water circulation unit have overlapping part.
The domestic hot-water unit, it mainly acts on is to produce the domestic hot-water from the heat of solar energy recirculated water.It comprises the domestic water heat exchanger that is used for the exchange heat of solar energy recirculated water is formed to domestic water the domestic hot-water, described domestic water heat exchanger is arranged in the water circulation pipe of described solar energy water cycling element, be used to store domestic hot-water's domestic water storage device, be used for convection current birth and apply flexibly the domestic hot-water of water storage apparatus and carry out electrically heated domestic water electric heater unit.For the user who does not use bathtub, also can save the domestic water storage device.The domestic water electric heater unit adopts device for heating electric heating membrane, device for heating electric heating membrane is a kind of electric heater unit that the current of its inner chamber of flowing through is carried out infrared heating, the concrete structure of this device for heating electric heating membrane was disclosed among the CN1693810A on November 9th, 2005 as applicant of the present utility model, the characteristics of device for heating electric heating membrane are promptly logical instant heating, and are easy to use.
Control module, it mainly comprises central processing unit and the temperature sensor that is arranged in above-mentioned each unit, temperature sensor is mainly used in leaving water temperature and return water temperature, solar energy circulating water temperature and domestic hot-water's temperature of the leaving water temperature of surveying room temperature, outside air temperature, heating water and return water temperature, chilled water, the temperature signal and the design temperature that detect according to the said temperature sensor compare, thereby determine the automatic unlatching of each circulating pump, each electric heater unit and compressor etc., close adjusting with power automatically.
Operation principle is as follows:
When heat pump unit is in when heating state, compressor is sent the gaseous state heat-exchange working medium of HTHP into the heat pump indoor heat exchanger, the liquid of warm high pressure and release heat in becoming, and therefore, this moment, the heat pump indoor heat exchanger played the effect of condenser; The liquid heat exchange working medium of warm high pressure is through the throttling step-down of device for drying and filtering, liquid-sighting glass and expansion valve in being somebody's turn to do, become the liquid of low-temp low-pressure, evaporate by the heat that absorbs wherein in air source heat exchanger, solar heat exchanger or heat-exchange working medium electric heater unit through liquid-dividing head again, become the gas of low-temp low-pressure, so in fact air source heat exchanger, solar heat exchanger and heat-exchange working medium electric heater unit have played the effect of evaporimeter; The gas converting heat working medium of this low-temp low-pressure flows back to the compressor air suction mouth, finishes a working cycles.
For heat-exchange working mediums such as R22, R407A, when temperature was lower than 0 ℃, the thermal efficiency of common heat pump seriously descended, and it places outdoor heat exchanger frosting can occur even freezes, and causes shutting down.But as the disclosed heat pump unit of present embodiment, because it is a kind of heat pump of many thermal source inputs, therefore under temperature was lower than 0 ℃ situation, if the solar energy circulating water temperature is enough high, this heat pump unit still can be transformed into heat of high temperature with the low-temperature heat quantity in the solar energy recirculated water.Temperature is when 0 ℃ to-3 ℃ stage, if atmospheric humidity reaches dew point, preferential by the defrosting of operation solar energy recirculated water, when solar water-temperature descends, just stop the circulation of solar energy water, automatically start the direct heat exchanging working medium of heat-exchange working medium electric heater unit and heat, thereby finish defrosting, the described device for heating electric heating membrane of the preferential employing of heat-exchange working medium electric heater unit.
When temperature below-3 ℃ the time, because temperature is lower, or air humidity is big, the air source heat pump Energy Efficiency Ratio descends, and the heat exchange ratio is 1: 1, and this moment, control module was closed heat pump automatically, and startup heating water power heater heats heating recirculated water, heating water power heater also is to adopt device for heating electric heating membrane, and control module is regulated the heating power of heating water power heater automatically according to the water temperature of setting, and lacks 1 ℃ of 1 ℃ of compensation.After reaching the water temperature of setting, regulate heating power automatically and keep water temperature constant, when arriving the setting room temperature, temporarily stop the operation of heat pump unit.Along with conversion round the clock and meteorological the variation, when satisfying solar units or heat pump unit service condition, control module then stops heating water power heater automatically, and starts solar energy cycling element or heat pump unit simultaneously.
When heat pump unit is in refrigerating state, by cross valve, regulate the flow direction of heat-exchange working medium, at this moment, the heat pump indoor heat exchanger absorbs heat, played the effect of evaporimeter, and the air source heat exchanger is emitted heat, has played the effect of condenser.In the accompanying drawing, the dotted portion of heat pump unit has been expressed the flow direction of heat-exchange working medium, has then expressed the flow direction of kind of refrigeration cycle water accordingly at the dotted portion of chilled water cycling element.Such adjusting is that those of ordinary skill in the art is known.
By kind of refrigeration cycle water, cold is delivered to the room that each need freeze, can reduce the expense of the device that installs an air-conditioner greatly, reduce the quantity that building hangs air-conditioner, can also reduce the energy consumption of refrigeration by cold balancing greatly.
The central air conditioner system that the utility model disclosed, its solar energy recirculated water unit, heating water circulation unit, chilled water cycling element, heat pump unit and domestic hot-water unit are not only separate but also interrelated, thereby solar energy, air energy and electric energy are organically combined, brought into play advantage separately to greatest extent, really accomplished mutual supplement with each other's advantages, make the central air conditioner system can stable operation under round-the-clock condition, and saved the energy to greatest extent.
