In the prior art, the cabinet air conditioner of pump type heat except freezing summer, also is used for winter heating, and the hot blast when heating is blown out by the top air outlet equally.Because hot-air is toward the upper reaches, the hot blast of producing by boasting like this can still cannot make that but the temperature of lower space obviously improves so that the temperature of upper space obtains raising.The result who causes be the temperature experienced of people's brain obviously than foot height, just in time to be lower than the foot environment temperature opposite with head environment temperature that comfortableness requires.
If obtain human body comfort preferably when warming up equally in order to make to send winter, the air supply mode in the time of preferably will heating makes the bottom air-supply into.But,, be difficult to realize such requirement if the structure of air-conditioner is not done big change because the arrangement of air outlet, blower fan, evaporimeter is all definite; And if do big change, then can improve the cost of air-conditioner again greatly.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, design provides a kind of and both can improve the thermal comfort in winter, need not do the cabinet type heat pump type air conditioner that the hot blast function is sent in the bottom that has of big change again for the structure of original air-conditioner, mainly comprise off-premises station, evaporimeter, main chamber's inner blower, last air outlet, following indoor fan, electric heater, following air outlet, return air inlet, partition air door.
The present invention has increased by one in existing pump type heat cabinet air conditioner can select the bottom heat supply function that starts, only when air-conditioner is in heating condition, just can enable this function.When this function is enabled, the energising of the electric heater of bottom, following indoor fan starts, and following air outlet is opened, and partition air door is closed naturally and indoor apparatus of air conditioner is separated into two air flow circuits up and down.This moment, the last air outlet and the following air outlet of air-conditioner will have hot blast to send simultaneously.
When air-conditioner is in the heating condition (perhaps cooling condition) that the top heat supply is only arranged, the electric heater outage of bottom, following indoor fan is not worked, following air outlet is closed, partition air door relies on the air draught effect of main chamber's inner blower and opens in addition, and all flow through evaporimeter and blow out by last air outlet from the return air inlet inhaled air.
The present invention has significant advantage and good effect.The first, the present invention has the function that hot blast is sent in the bottom, the comfort level in the time of can improving the room effectively and heat.The second, the mechanism that is used to increase bottom air-supply function is simple, need not do big change for original cabinet-type air conditioner, and cost increases less.The 3rd, the present invention can increase total heating capacity in winter, and is particularly low in outdoor temperature, and when operation of heat pump efficient was low, the increase of heat was more obvious.
