The air regulating device consists of a condenser (2), a frequency conversion compressor (3), a circulation fan (4), a water exchange evaporator (5), a heat-insulation box (9), a throttle mechanism and a control system, at least one air inlet (8) and an air outlet (1) are respectively arranged on a front surface and a rear surface of the heat-insulation box (9), the condenser (2), the frequency conversion compressor (3), the circulation fan (4), the water exchange evaporator (5) and the throttle mechanism are placed in the heat-insulation box (9), wherein the condenser (2) is mounted nearby the air outlet (1), and the circulation fan (4) is placed on the inner side of the condenser (2). Compared with an existing heat pump air regulating device, the air regulating device of the water circulation direct-current frequency conversion heat pump is obvious in energy-saving effect and high in thermal energy utilization rate, and the evaporator cannot be frosted.
Description
Technical field
The utility model relates to a kind of conditioner, particularly a kind of water circulation DC frequency-changing heat pump conditioner, and it is applicable to that constant-temperature house, hatch machine etc. need to keep the place of steady temperature.
Background technology:
General electrothermal tube or the hot-water boiler of adopting such as greenhouse and constant-temperature house is as thermal source at present, and it is low that electrothermal tube exists efficiency, and power consumption is bigger, starts shortcomings such as frequent; Hot-water boiler needs burning coal, and needs staff on duty, though use cost is low than electrothermal tube, and not environmental protection.
Heat pump belongs to new energy technology, not only energy-conservation but also environmental protection.Application number is that 200710191653.2 patent application document discloses a kind of air energy hatching machine, and this hatch machine adopts air source heat pump, and utilizes along circulation and contrary circulation and control temperature, has following shortcoming:
(1) cross valve starts frequently, can cause gas-liquid to impact to whole heat pump when switching at every turn, can influence the normal use and the life-span of compressor when serious;
(2) just contrary circulation when temperature reaches thermostat temperature, this moment, incubator did not need heat, but also at consumed power, energy-saving effect is not obvious;
(3) when environment temperature is low, the easy frosting of evaporimeter;
(4) non-uniform temperature in the thermostatic box.
Summary of the invention
The purpose of this utility model is to provide the water circulation DC frequency-changing heat pump conditioner of the more obvious and evaporimeter frost-free of a kind of energy-saving effect.
For achieving the above object, the solution that the utility model adopts is: this conditioner comprises condenser, compressor, evaporimeter, the insulation casing, throttle mechanism and control system, compressor, condenser, throttle mechanism and evaporimeter head and the tail successively connect and compose heat pump heating system, described evaporimeter adopts water exchange evaporimeter, compressor adopts frequency-changeable compressor, condenser, frequency-changeable compressor, evaporimeter and throttle mechanism are installed in the insulation casing, on former and later two faces of insulation casing, be respectively equipped with at least one air inlet and an air outlet, condenser is near air outlet, in the installed inside of condenser circulating fan arranged.
Control system mainly is made up of single-chip microcomputer and a plurality of sensor, is used to finish thermostatic box temperature sampling, frequency conversion drive, all kinds of protections etc.
In the air inspiration heat pump insulation casing that circulating fan is lower with thermostatic box bottom relative temperature during the utility model work, after the condenser heating, enter in the thermostatic box, the interior temperature of thermostatic box is risen by the air outlet pipeline.When in the thermostatic box during temperature superelevation, open the overtemperature air door and enter cool ambient air.
The utlity model has following advantage: (1) is owing to adopted variable-frequency driving technique, so energy-saving effect is more obvious, and the heat pump life-span is long; (2) owing to adopted water exchange evaporimeter, so evaporimeter can frosting; (3) temperature is even in the thermostatic box.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is made up of condenser 2, frequency-changeable compressor 3, circulating fan 4, water exchange evaporimeter 5, insulation casing 9, throttle mechanism and control system, condenser 2, frequency-changeable compressor 3, circulating fan 4, water exchange evaporimeter 5 and throttle mechanism all place in the insulation casing 9, and refrigerant uses environmental protection R410a.The front end face of insulation casing 9 is provided with an air inlet 8, rear end face is provided with an air outlet 1, condenser 2 is installed by air outlet 1, and circulating fan 4 is installed in the inboard of condenser 2, is used in the air inspiration heat pump insulation casing 9 that thermostatic box bottom relative temperature is lower.Water exchange evaporimeter 5 is provided with water inlet 6 and delivery port 7, the water of each heat pump demand is by the pipeline parallel connection, utilize water pump to be recovered to the heat exchange water tower or geothermal heat exchanger carries out heat exchange, water valve 10,11 is installed on the pipeline of water tower, water valve 12,13 is installed on the pipeline of geothermal heat exchanger.Closed water valve 12,13 when summer, environment temperature was high, open water valve 10,11 usefulness water towers and carry out heat exchange, open water valve 12,13 winter when environment temperature is very low, close water valve 10,11 and utilize underground heat to carry out heat exchange, improved the efficiency of heat pump.
Control system mainly is made up of single-chip microcomputer and a plurality of sensor, is used to finish thermostatic box temperature sampling, frequency conversion drive, all kinds of protections etc.Power frequency AC becomes direct current through behind the rectifying and wave-filtering, and dc source is added on the power model, and power model offers frequency-changeable compressor 3 on demand by after the control of control system.
During the utility model operate as normal, frequency-changeable compressor enters condenser release heat energy at the control lower compression refrigerant of drive circuit, and by circulating fan and air channel heat energy is taken in the thermostatic box.Refrigerant is then come the heat absorption of water exchange evaporator evaporation by choke valve, gets back to compressor compresses then and enters next circulation.In the thermostatic box appropriate location temperature sensor is installed, single-chip microcomputer compares calculating to user's design temperature and thermostatic box actual temperature, controls frequency-changeable compressor by the output of power model then, to reach the purpose of constant temperature.When single-chip microcomputer detects overcurrent, abnormity of power supply, the current water temperature is unusual, system pressure is unusual etc. will be by oneself, block output in case of necessity and start standby heater simultaneously.
