Problems solved by technology

[0003] But as we all know, the climatic conditions in various places vary greatly, and the living habits and consumption levels of consumers are also uneven. In some places, air conditioners only need cooling functions, and in some places, air conditioners need both cooling and heating functions, but there are also many Local air conditioners only need the heating function, and even in the same place, some people only need the cooling and heating functions, and some people only need the heating function. The performance optimization of this part of consumers
Because the pure electric air conditioner consumes too much electricity when heating, the heat pump type and the heat pump assisted electric type need to add a four-way reversing valve and other auxiliary devices. Completely redundant, they not only greatly increase the cost of the air conditioner, but also reduce the reliability of the whole machine

Embodiment Construction

[0021] figure 1 It shows the heating cycle principle of the healthy heat pump provided by the present invention. During heating, the refrigerant flow direction is: compressor 1 → condenser 2 → capillary tube 4 → evaporator 3 → compressor 1, where the condenser 2 is fixed in the indoor unit, The evaporator 3 is fixed at the outdoor unit; considering the defrosting needs during heating in winter, a defrosting branch pipe 5 is connected in parallel to the exhaust pipe of the compressor 1, and the defrosting branch pipe 5 is connected to the evaporator 3 At the bottom, there is a normally closed defrosting solenoid valve 6 in series with the defrosting branch pipe 5. When the air conditioning control unit detects that the evaporator 3 has accumulated frost and reaches the defrosting start condition, it will be opened intermittently according to the preset defrosting program. The defrosting solenoid valve 6 allows the high-temperature exhaust gas from the compressor 1 to directly e...

Abstract

A heat pump is prepared as setting evaporator in outdoor unit of air conditioner and condenser in indoor unit of air conditioner; setting evaporator, condenser, compressor and throttle unit to be worked only on heating mode for providing consumer an air conditioner only with heating function.

Description

technical field [0001] The invention relates to a room air conditioner. Background technique [0002] Existing room air conditioners can be divided into two types according to their basic functions: single-cooling type and heating and cooling type. At the same time, the design and manufacture of room air conditioners are mainly based on the cooling function, so the indoor unit contains the evaporator, and the outdoor unit contains the condenser. In order to realize heat pump heating, room air conditioners without exception need to add a four-way reversing valve to change the refrigerant flow direction, temporarily turning the evaporator of the indoor unit into a condenser, and temporarily changing the condenser of the outdoor unit into an evaporator . However, the working conditions of the room air conditioner during cooling operation and heat pump heating operation are very different. It is difficult to achieve the best effect of heating operation at the same time when th...
