Problems solved by technology

However, there is a problem that when such an air-conditioning operation continues, when there is an enthalpy difference between the air sucked in from outside the bathroom and the air in the bathroom, part of the heat after the temperature adjustment of the bathroom leaks to the outside, resulting in Increased heat recovery loss and low air conditioning efficiency

Embodiment approach 1

[0043] figure 1 It is a figure which shows the air path structure and the cooling medium circuit of the bathroom air-conditioning apparatus concerning Embodiment 1 of this invention. like figure 1 As shown, the main body 1 of the bathroom air conditioner is arranged in the ceiling of the bathroom 2, and the suction port 3 and the blowing port 4 are opened on the lower surface of the main body 1 to communicate with the bathroom 2. Here, the suction port 3 and the blowing port 4 are opened at different positions in the bathroom 2 . In addition, one end of an exhaust duct 5 is connected to the main body 1 , and the other end of the exhaust duct 5 communicates with an outdoor outlet 6 . Inside the main body 1, a circulation air path 7 communicating with the suction port 3 and the blowing port 4, and a ventilation air path 8 communicating with the suction port 3 and the exhaust duct 5 are formed. A circulation fan 9 is arranged in the circulation air passage 7 , and a ventilatio...

Embodiment approach 2

[0086] Next, a method for increasing the energy efficiency by increasing the heat recovery amount of the heating operation will be described. Figure 7 It is a schematic cross-sectional view of the bathroom air conditioner according to Embodiment 2 of the present invention.

[0087] Figure 7 bathroom air conditioners and Figure 5 The difference of the bathroom air conditioner is that the partition wall 52 which divides the circulation air duct 7 and the ventilation air duct 8 is provided. In addition, the compressor 13 , the decompression mechanism 15 , and the control device 54 are provided in the ventilation duct 8 , and the ventilation fan 10 and the heat absorber 24 are provided in this order from the outdoor air outlet 6 side. in addition, Figure 7 The bathroom air conditioner of 2000 only performs heating operation, so there is no flow path switching valve.

[0088] Figure 7 The bathroom air conditioner has an opening and closing plate 53 that can switch the air...

Abstract

A bathroom air conditioner having a refrigeration circuit having connected by piping a compressor, a heat radiator, a pressure reduction mechanism, and a heat absorber, a circulation airflow path, and a ventilation airflow path. The heat radiator and a circulation fan for circulating air in a bathroom are arranged in the circulation airflow path, and the heat absorber and a ventilation fan for discharging air in the bathroom outdoors are arranged in the ventilation airflow path. The bathroom air conditioner further has a control device which, when, in a heating operation, the temperature in the bathroom is higher than a predetermined value, reduces the amount of airflow produced by the ventilation fan.In the heating operation, the air conditioner heats the inside of the bathroom by allowing, by means of the heat absorber, refrigerant to absorb heat from the air in the bathroom and also allowing, by means of the heat radiator, the refrigerant to release heat to the air in the bathroom.

Description

technical field [0001] The invention relates to a bathroom air conditioner which uses a heat pump to regulate the temperature of the bathroom. Background technique [0002] In a conventional bathroom air conditioner using a heat pump, for example, one heat exchanger of the heat pump releases or absorbs heat from air taken in from outside the bathroom, and blows the air into the bathroom. Furthermore, the other heat exchanger of the heat pump absorbs or releases heat from the air discharged from the bathroom to the outside, thereby adjusting the temperature of the bathroom (for example, refer to Patent Document 1). [0003] Such a bathroom air conditioner adjusts the temperature of the bathroom by recovering the heat of the air discharged from the bathroom to the outside and adding heat to the air sucked in from outside the bathroom. However, there is a problem that when such an air-conditioning operation continues, when there is an enthalpy difference between the air sucked...
