Description
Technical field
The present invention relates to a kind of air-replacement device, specifically, relate to a kind of heat-pump-type constant temperature and humidity intelligent air displacer.
Background technology
At present, heat-pump-type ventilation system is factory or family to take a breath or reaching the object of air-conditioning and the product generally adopted, most Heatpump (heat pump) formula air exchange system is made up of indoor set and off-premises station, and be arranged on indoor and outdoors respectively, belong to divergence type Heatpump (heat pump) air exchange system.The indoor set also had and off-premises station are one, are arranged on the place such as window or balcony, carry out Heatpump (heat pump) the formula air exchange system of air-breathing and exhaust through wall and window.
These systems, along with the increase of refrigerating/heating power demand, not only the volume of its off-premises station and indoor set can increase, and can bring very large vibrations during the compressor operating of off-premises station inside, and what adopt so general is divergence type Haetpump (heat pump) air exchange system.
The principle of above-mentioned Heatpump (heat pump) formula air exchange system forms heat exchange action by being arranged between the gas coolant of indoor low-temp low-pressure and air, the indoor set of supply hot blast or cold wind is housed, to ensure that indoor set plays hot-swap feature in inside.It is generally made up of the off-premises station and indoor set that refrigerant are carried out compress condensing expansion, and be connected and installed by refrigerant pipe between off-premises station and indoor set, indoor set forms the built-in evaporimeter of heat exchange action by the cold media gas by low-temp low-pressure, the suction inlet of Interior Space aspiration/row and exhaust outlet, room air is discharged to indoor blower fan again by evaporimeter and motor forms, the suction inlet of Interior Space aspiration/row and exhaust outlet are then arranged on above-mentioned evaporimeter side.
Off-premises station is the suction inlet and outlet being inhaled by outdoor air/arranged, the compressor (compressor reducer compressed by the refrigerant HTHP of evaporimeter above-mentioned) installed in above-mentioned machine, condenser (converting the machine of the liquid coolant of middle temperature high pressure after carrying out heat exchange by the refrigerant of compressor with outdoor air to), the decompression valve such as capillary or electric expansion valve (utilizing expansion means to make the machine of the gas coolant being become low-temp low-pressure by the refrigerant of condenser) and be arranged on above-mentioned condenser side and make outdoor air by the axial flow blower of condenser, motor forms.These motors are single-phase or 3 phase capacitor motors, employing be the form that the rotor in casing rotates in stator.
Above-mentioned off-premises station, in order to improve air-supply efficiency, is equipped with suction inlet 3 sides, exhaust outlet is housed above, during outdoor fan running, sucks air from 3 sides, after carrying out heat exchange, discharges from top the air after heat exchange.At this moment above-mentioned compressor, condenser, expansion gear, evaporimeter are connected by refrigerant pipe mutually, and refrigerant forms approach in order by compressing by above-mentioned, condensing, expand, and evaporation circulates.But, this existing air conditioning off-premises station, along with the increase of urban population and building density, the strengthening of environmental management, be subject to restriction is installed, the reason of the noise of machine own and hot driving causes the controversial issue of periphery occupant, and particularly sweeping high-rise building relates to attractive in appearance and noise, off-premises station can only be installed on balcony.
On the contrary, another kind of from sucking air above and after carrying out heat exchange, then from above the air adjustment off-premises station that formula is inhaled/arranged in the front that the air after heat exchange is discharged generally being adopted at large-scale building.But the heatpump formula off-premises stations suction area that the Heatpump (heat pump) of front suction and row's mode inhales and arrange than above-mentioned 3 with off-premises station is little, so the problem that air-supply efficiency and heat exchanger effectiveness reduce.
Further, air adjustment System is in the past the refrigerating/heating device being adjusted to main purpose with indoor temperature, and with humidifier and the dehumidifier of indoor humidity adjustment, but exist can not the problem of effective operation for humidifier and dehumidifier.
