Serial air conditioner and temperature regulating box all-in-one machine and operation control method thereof

Abstract

The invention discloses an air conditioner and temperature regulating box all-in-one machine, which comprises a compressor, an outdoor heat exchanger and a throttle mechanism which are sequentially connected through a main pipeline. The output end of the compressor is connected with the input end of the outdoor heat exchanger. The output end of the outdoor heat exchanger is connected with the input end of the throttle mechanism. The all-in-one machine additionally comprises an indoor temperature regulating box heat exchanger and an indoor air conditioner heat exchanger. The input end of the indoor temperature regulating box heat exchanger is connected with the output end of the throttle mechanism. The output end of the indoor temperature regulating box heat exchanger is connected with the input end of the indoor air conditioner heat exchanger. The output end of the indoor air conditioner heat exchanger is connected with the input end of the compressor. Since the indoor air conditioner heat exchanger and the indoor temperature regulating box heat exchanger of the all-in-one machine are connected in series, the problem of backflow caused by unbalanced pressure is solved.

Description

technical field [0001] The invention relates to the technical field of an air conditioner and a thermostat box integrated machine, in particular to a serial air conditioner and a thermostat box integrated machine and an operation control method thereof. Background technique [0002] The existing air conditioner and temperature control box integrated machine has the following two production methods: [0003] 1. The air conditioner and the temperature control box each have a set of independent all-in-one machines; the two are integrated for a certain purpose during the manufacturing process. The simple superposition of the two all-in-one machines not only increases the space size for no reason, but also has no innovation in the technical field , which will not be repeated here. [0004] 2. The air conditioner and the temperature control box share a set of all-in-one machines, and the indoor air conditioner heat exchanger and the indoor temperature control box heat exchanger a...

Problems solved by technology

Then, after passing through the two heat exchangers, when the refrigerant converges together, the refrigerant in the heat exchanger branch of the indoor air conditioner will flow back to the heat exchanger branch of the indoor thermostat box; this will seriously affect the performance of the indoor air conditioner and the indoor thermostat box

In response to this situation, the existing solution is to add a booster pump at the outlet of the refrigerator evaporator; the disadvantage is that not only the cost is high but also the efficiency is very low

[0005] On the other hand, the heat exchanger of the indoor air conditioner adopts fan forced convection heat exchange, while the heat exchanger of the indoor thermostat box relies on radiation heat exchange. , the evaporation temperature of the indoor air conditioner heat exchanger is higher than that of the refrigerator heat exchanger, and most of the refrigerant flows to the indoor thermostat heat exchanger with lower pressure, resulting in a significant reduction in air conditioning capacity

In response to this situation, the existing solution is to add a throttling device at the inlet of the refrigerator. The disadvantage is that the refrigerant in the heat exchanger of the indoor thermostat box cannot flow out from the outlet and will cause backflow, which will affect the efficiency of the all-in-one machine.
