CN201273665Y - Apparatus of small sized air conditioner for energy saving by condensed water - Google Patents

Abstract

The utility model relates to a device in which a small air conditioner uses condensed water to save energy, and the condensed water is led to cool the working medium in a condenser through an electric water pump and a by-pass pipe at the side of the condenser. The electric water pump is connected with a duct, a condensed water sleeve, a water return duct and a condensed water return leading-in pipe in sequence, wherein, the condensed water sleeve is mutually sleeved with a refrigerant coil in the condenser together, and the condensed water return leading-in pipe is connected with the upper part at the side of a water holding tray; the refrigerant coil and the condensed water sleeve which are mutually sleeved together are actually a heat exchanger which gas is mutually separated from liquid. When the condensed water in the water holding tray is accumulated to a certain degree, the electric water pump is started up to enable the condensed water to circulate in a circulation pipeline and forcedly cool the condenser. The way not only ensures the full heat exchange of the condenser, but also eliminates the 'dead ends' which can not exchange the heat when the middle local part is purely sprayed; meanwhile, compared with the prior art, the utility model can avoid environmental pollution, protect buildings, reduce the 'heat island effect', save energy and reduce consumption, improve the operating condition of the air conditioner, and the like.

Description

Small air-conditioning system utilizes the device of condensation water for energy conservation

Technical field

The utility model relates to air-conditioning, relates in particular to small-sized air conditioner.

Background technology

In summer, because the surface temperature of A/C evaporator is lower than the dew-point temperature of air, airborne water vapour can be in the evaporator surface formation condensate water of condensing.At present to the general method of disposal of condensate water be discharged into after with drainpipe it being extracted outdoor.In most of the cases, this discharging not only influences outdoor environment, also can pollute even damage building; To the pedestrian who below building, walks about, also be a kind of puzzlement.The more important thing is that these random dischargings that do not have through the low-temperature condensate of suitably handling still are a kind of energy (electric energy) waste.Application number is 2006201118711, name is called " a kind of split-type air conditioner that utilizes condensation water for energy conservation " patent application provides a kind of technical scheme that can overcome above-mentioned defective to a certain extent.This scheme is one group of its underpart to be set the weep pipe of several weepers is arranged or drip case (in this case above the condenser in the air-conditioner outdoor unit, be referred to as sprinkler), pass through one section conduit (in this case on the top of this weep pipe or the case that drips, be called bypass pipe) with indoor apparatus of air conditioner in that condensate water drip pan UNICOM of evaporimeter below, remove to cool off this condenser the condensate water in the condensate water drip pan is guided to the condenser top.From effect, this technical scheme has reached purpose really to a certain extent.Yet, this heat exchange method (especially wherein only utilizing the sort of structure of conducting oneself with dignity and electric pump not being installed) that only down flows to the condenser top by condensate water, not only abundant inadequately aspect heat exchange, but also have " dead angle " that can not carry out heat exchange.

The utility model content

The purpose of this utility model provides the device that a kind of small air-conditioning system utilizes condensation water for energy conservation, utilizes the device of condensation water for energy conservation in this small air-conditioning system, can further improve energy-saving effect.

For achieving the above object, the utility model provides a kind of like this small air-conditioning system to utilize the device of condensation water for energy conservation.Aspect same as the prior art is, this air conditioner comprises and has evaporimeter indoor set within it and have condenser off-premises station within it, a condensate water drip pan is arranged below the evaporimeter of indoor set, a condensate water fairlead is arranged in the bottom of this condensate water drip pan or near on the sidewall of bottom.After the condensate water fairlead, be orderly connected with electric water pump, bypass pipe and be positioned at sprinkler above the condenser.Its improvements are that an electric control valve is installed in bypass pipe; Piping node place between electric water pump and this electric control valve is orderly connected with condensate water sleeve pipe, one section backwater conduit and one section coagulation hydroenergy backwater inlet tube that is connected in the top, side of drip pan that one section conduit, one section and cold-producing medium coil pipe in the condenser set with each other---form a condensate circulating water pipe road.Wherein, " heat exchanger " that in fact cold-producing medium coil pipe that sets with each other and condensate water sleeve pipe isolate mutually with regard to a gas, liquid.After the condensate water productive set in the drip pan unloaded phenomenon can not take place to electric water pump, the electric water pump starting allowed this " heat exchanger " to enter duty, condensate water is circulated in circulation line to force the cold-producing medium in this cold-producing medium coil pipe of cooling; When the condensate water productive set in the drip pan to may overflow the time, the motorized adjustment opening of valves allows a part of condensate water be sprayed onto condenser by bypass pipe and makes full use of.

Superiority of the present utility model is as follows:

Because the utility model has increased " heat exchanger " that utilizes condensate water to force the cooling refrigeration agent, therefore, compared with prior art, not only can guarantee sufficient heat exchange, but also eliminate " dead angle " that can not carry out heat exchange.So, avoid environmental pollution, protection building, reduce " tropical island effect ", energy-saving and cost-reducing and improve the aspects such as operating condition of air conditioner, all increase than prior art.

Below in conjunction with accompanying drawing the utility model is further described.
