DEVICE FOR HEATING THE EVAPORATOR OF AN OUTDOOR AIR HEAT PUMP

The invention refers to the heating and cooling systems with heat pumps, which have open type evaporators. A device for heating the evaporator of an open outdoor air heat pump, for example, with warm air removed out by the ventilation system from a pigsty, is offered. The invented device forms an air flow canal B around the vertically fixed open type evaporator (8) due to the air pressure which appears during the work of the pigsty ventilation system. The air flow in the canal automatically covers the evaporator, but when the ventilator does not work, opens the evaporator and it continues to work as the open type evaporator. The space B is formed by a corrugate tube (2), made of elastic material, the bottom end of which is connected to the ending (9) of a foundation (7), but the top end is fixed to a cover (1). If the outdoor temperature becomes lower than the temperature of the air removed out by the ventilation system, the warm air flow is directed to a space A. The force of the air flow pressure lifts up the cover (1) forming the space B, where the whirling warm air intensively gives the heat to the evaporator and being cooled down flows out to the atmosphere, but the condensate flows away from the device through a canal (6). In order to put the cover (1) on the evaporator (8) and it could move vertically along the pipe ribs of the evaporator (8), and after the heat exchange the cool air could flow out, the corresponding openings in the cover (1) are made. Izgudrojums attiecas uz sildīšanas un dzesēšanas sistēmām ar siltuma sūkņiem, kas aprīkoti ar atklāta tipa iztvaicētājiem. Piedāvāta ierīce āra gaisa siltuma sūkņa atklāta tipa iztvaicētāja apsildīšanai, piemēram, ar siltu gaisu no cūkkopības kompleksa kūts ventilācijas sistēmas. Izgudrotā ierīce silta gaisa plūsmas padeves laikā ar ventilācijas sistēmas gaisa spiediena palīdzību ap vertikāli nostiprinātu atklāta tipa iztvaicētāju (8) izveido gaisa plūsmas kanālu B, kurš, darbojoties ventilatoram, automātiski aptver iztvaicētāju, bet ventilatoru izslēdzot - atsedz iztvaicētāju, ļaujot tam darboties atklātā tipa iztvaicētāja darba režīmā. Piepūšamo telpu B veido iztvaicētāju aptveroša elastīga materiāla gofrēta caurule (2), kuras apakšējais gals piestiprināts pie iztvaicētāja pamatnes (7) esošās apmales (9), bet augšējais gals savienots ar vāku (1). Ja apkārtējās vides temperatūra kļūst zemāka nekā ventilācijas sistēmā esošā izvadāmā gaisa temperatūra, tad no ventilācijas sistēmās nākošo siltā gaisa pl
