Description

Conditioner

Technical field

The utility model relates to a kind of conditioner.

Background technology

Adjustment in the existing domestic communication station mainly contains dual mode, a kind of structure that is similar to the split-type air conditioner of domestic air conditioning, promptly form refrigerant circulation loop by condenser, evaporimeter, compressor and restricting element, under the compressor effect, cold-producing medium circulates, freeze to the machine station is indoor by evaporimeter, but the energy consumption height of this structure, long playing fault is many; Another kind is to adopt air-to-air heat exchanger, the housing that is heat exchanger is provided with extraneous wind inlet, extraneous wind outlet, indoor wind inlet and the outlet of indoor wind, extraneous wind inlet and the outlet of extraneous wind connect and formation exogenous wind passage, indoor wind inlet and the outlet of indoor wind connect and the interior wind passage of formation, interior wind passage, the exogenous wind passage all passes heat-exchanger rig and forms heat exchange structure, promptly this structure be with indoor hot blast directly in interior wind passage with the exogenous wind passage in the relatively low cold wind of temperature carry out heat exchange, the good energy-conserving effect of this heat exchange mode, but it is too high to work as indoor temperature, or ambient temperature is when too high, and its heat exchange effect is undesirable.

Summary of the invention

The purpose of this utility model is to provide a kind of energy-saving effect and the more satisfactory conditioner of heat exchange effect.

The utility model is achieved through the following technical solutions:

A kind of conditioner, be provided with heat-exchanger rig and separate interior wind passage, exogenous wind passage in this conditioner, should in wind passage, exogenous wind passage communicate with air channel, the outer air channel of heat exchange in the heat exchange of heat-exchanger rig respectively, be equipped with blower fan in this exogenous wind passage, the interior wind passage; It is characterized in that this conditioner comprises the bypass air channel that communicates with the exogenous wind passage, and the refrigerant circulation loop that comprises condenser, evaporimeter, compressor and restricting element; This evaporimeter, condenser place respectively in interior wind passage, the exogenous wind passage, are provided with the movable air door of its switching of control outside bypass air channel and heat exchange between the air channel, and compressor and each blower fan all are electrically connected with control circuit.

In the utility model, when if outdoor temperature is low, blower fan in directly opening in wind passage, the exogenous wind passage, movable air door communicates the outer air channel of exogenous wind passage and heat exchange and exogenous wind passage and bypass air channel is cut off, make room air and outdoor air by the heat-exchanger rig heat exchange, the little energy that consumes, and the mechanism of operation is few, and long-play also is difficult for producing fault; If outdoor environment temperature is too high, then open compressor, movable air door cuts off the outer air channel of exogenous wind passage and heat exchange and the exogenous wind passage is communicated with the bypass air channel, freezes the refrigerating efficiency height of this mode by evaporimeter; This shows that the utility model can be selected different mode of operations according to indoor and outdoor environment, can effectively satisfy powerful cooling requirement, again can be energy-conservation as much as possible.

Described movable air door is by drive mechanism, and driving mechanism and described control circuit are electrically connected.Control moving of movable air door by driving mechanism, automaticity height, easy operating, driving mechanism can adopt pinion and-rack structure or other structure and by motor as power resources, motor is controlled by control circuit.

Described movable air door is two, and one of them movable air door is located at outer air channel of described heat exchange and the forward end position in bypass air channel, and another movable air door is located at the outer air channel of described heat exchange and back-end location is leaned in the bypass air channel.Under the compressor cooling pattern, the outer two ends, air channel of heat exchange all are closed, and the heat of avoiding condenser to distribute imports in the outer air channel of heat exchange, influences refrigeration.

Described heat-exchanger rig is a heat exchanger core, is provided with the multilayer heat exchanger fin in this heat exchanger core, forms air channel in the described heat exchange, the outer air channel of heat exchange between each adjacent heat exchanger fin at interval.

This conditioner also includes temperature sensor, and temperature sensor and described control circuit are electrically connected.In the course of the work, come sensing ambient temperature, indoor temperature and entire system duty by temperature sensor, and select corresponding work mode with this, particularly, described temperature sensor is a plurality of, is located on the described evaporimeter at least, on the condenser, in the import of interior wind passage and outlet, the exogenous wind passage.

In the utility model, the refrigerant circulation loop that forms by condenser, evaporimeter, compressor and restricting element connection, this is a prior art, does not do too much description.
