Abstract
The utility model relates to a heat pump air conditioner, which can improve the low-temperature heating capacity of an air conditioner. The exhausted gas of the compressor is directly led to the bottom of an outdoor machine via an electromagnetic valve; the temperature thereof is raised to promote the defrosting, the working condition of the compressor can be improved, and the heating capacity of the air conditioner can be improved thereby.
Description
The utility model relates to a kind of air-conditioner, particularly a kind of heat pump type air conditioner.
When heat pump type air conditioner heated, the outdoor heat converter bottom temp was lower, often the easiest frosting, even carry out defrost, the frost of bottom also is difficult for removing, and the refrigerant body temperature that enters compressor is spent low, make compressor be difficult to starting, and then influence the low-temperature heating ability of air-conditioner.
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of heat pump type air conditioner that can improve the air-conditioner low-temperature heating capacity is provided.
The purpose of this utility model can reach by following measure:
The utility model heat pump type air conditioner is by 1 compressor, 1 or many indoor sets, and the refrigeration system that 1 outdoor heat converter etc. are formed, the pipeline with circulation refrigerant body between each unit couples together.When heating, the refrigerant direction of flow is: compressor → cross valve → each indoor set → electric expansion valve → outdoor heat converter → cross valve → compressor.
When carrying out the defrost running, the cross valve commutation, the refrigerant direction of flow is as follows:
Compressor → cross valve → outdoor heat converter → electronic valve → each indoor set → cross valve → compressor, and, on compressor exhaust pipe, connect an arm, by magnetic valve and capillary, directly guide to the bottom of outdoor heat converter, the time opening magnetic valve quickens defrost, enable to finish up hill and dale rapidly defrost, thereby improve heating capacity of air conditioner.
The advantage of the utility model air-conditioner is that defrost is complete, improves working conditions of compressor, improves heating capacity of air conditioner.
Description of drawings: listed accompanying drawing is the systematic schematic diagram of the utility model air-conditioner, wherein, the 1st, compressor, the 2nd, cross valve, the 3rd, magnetic valve, the 4th, outdoor heat converter, the 5th, each indoor set, the 6th, electric expansion valve, the 7th, capillary.
Embodiment: as shown in drawings, with compressor 1, cross valve 2, each indoor set 5, electric expansion valve 6, off-premises station 4, and magnetic valve 3, capillary 7 is with coupling together by the pipeline of refrigerant body, form a refrigeration system, the time opening magnetic valve through the bottom of the direct inlet chamber outer heat-exchanger of capillary, carries out defrost with the part high-temperature exhaust air of compressor, like this, constitute the utility model air-conditioner.
Claims (1)
