Definitions

  • the present invention relates to air conditioning technology and more particularly, to a wall-mounted chilled water air conditioner, which has the water valve device accommodated in the electrical control panel.
  • a conventional wall-mounted chilled water air conditioner generally uses a water valve device for controlling the delivery of chilled water from the chiller unit toward the evaporator subject to the control of a controller.
  • the controller detects the indoor temperature, and turns off the water valve device to stop chilled water from entering the evaporator when the indoor temperature is below a predetermined temperature value, or turns on the water valve device when the indoor temperature surpasses the predetermined temperature value for enabling chilled water to enter the evaporator for lowering the indoor temperature.
  • This is the working principle of a chilled water air conditioner.
  • a conventional wall-mounted chilled water air conditioner a has component parts closely arranged inside the housing.
  • the electrical control panel, referenced by 20 is arranged at the right side relative to the evaporator, referenced by 10.
  • a water intake tube 301 and a water outlet tube 302 are arranged in the gap between the evaporator 10 and the electrical control panel 20 , and respectively connected to the water valve device (not shown).
  • the water valve device must be mounted at the back side of the housing or in the adjacent wall. It is a complicated work to make a hole in the wall for accommodating the water valve device and the related drip tray. This installation method is not acceptable for home use.
  • Taiwan Patent I 283286 equivalent to China Patent ZL 200510069154.7 , issued to the present inventor, teaches a measure to solve the problem of the aforesaid prior art design.
  • the length of the evaporator 10 is minimized so that a space b is left n the housing at one lateral side of the evaporator 10 for accommodating a water valve device 40 .
  • This design facilitates installation and is practical for home application.
  • shortening the length of the evaporator 10 relatively lowers the cooling capacity.
  • the size of the air conditioner must be relatively increased. Thus, for the sake of economic considerations, an improvement is necessary.
  • the present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a wall-mounted chilled water air conditioner, which has the water valve device accommodated in the electrical control panel so that the size of the cooling capacity of the evaporator can be maximized without increasing the dimension of the machine body.
  • a wall-mounted chilled water air conditioner comprises an evaporator, a drip tray arranged beneath the evaporator, a fan disposed between the evaporator and the drip tray, a fan motor and an electrical control panel arranged at one lateral side relative to the evaporator, and a circuit board unit installed in the electrical control panel and electrically coupled with the fan motor.
  • the electrical control panel defines an accommodation space in an upper front side thereof for accommodating a water valve device that is electrically coupled to the circuit board unit and has a water intake tube and a water outlet tube respectively connected to the evaporator.
  • the electrical control panel comprises a housing consisting of a front shell member and a rear shell member.
  • the front shell member is disposed at the bottom side relative to the water valve device.
  • the rear shell member is disposed at the rear side relative to the water valve device.
  • a water guide set is arranged at the bottom side relative to the water valve device, and adapted for guiding condensed water drops from the water valve device to the drip tray.
  • the drip tray comprises a backwardly extended water-guide hole, and a side hole connected to a water collection box at the bottom side of the electrical control panel by a connection tube.
  • the water collection box has a water pump and a water level sensor arranged therein and electrically coupled to the circuit board unit.
  • the fan motor is a DC motor controllable by the circuit board unit to achieve thermostat control, saving energy consumption.
  • a wall-mounted chilled water air conditioner in accordance with the present invention comprising an evaporator 1 , a drip tray 2 , a fan 3 , a fan motor 4 and an electrical control panel 5 .
  • the drip tray 2 is arranged beneath the evaporator 1 .
  • the fan 3 is disposed between the evaporator 1 and the drip tray 2 .
  • the fan motor 4 and the electrical control panel 5 are arranged at one lateral side relative to the evaporator 1 .
  • the electrical control panel 5 comprises a housing consisting of a relatively shorter front shell member 51 and a relatively taller rear shell member 52 , and a circuit board unit 6 installed in, for example, the rear shell member 52 (see FIG. 3 , FIG. 4 and FIG. 5 ).
  • the fan motor 4 is electrically coupled to the circuit board unit 6 .
  • the electrical control panel 5 defines an accommodation space S in an upper front side thereof, i.e., in the upper side relative to the front shell member 51 and front side relative to the rear shell member 52 for accommodating a water valve device 7 (see FIG. 4 and FIG. 5 ).
  • the front shell member 51 is disposed at the bottom side of the water valve device 7 ;
  • the rear shell member 52 is disposed at the front side of the water valve device 7 .
  • the water valve device 7 electrically coupled to the circuit board unit 6 , comprising a water intake tube 71 and a water outlet tube 72 respectively connected to the evaporator 1 .
  • the water valve device 7 is controlled to close or open the water intake tube 71 and the water outlet tube 72 .
  • a water guide set 8 (for example, a two-component water guide set, as shown in FIG. 3 and FIG. 4 ) is arranged at the bottom side of the water valve device 7 .
  • the water guide set 8 is arranged at the top side of the front shell member 51 of the electrical control panel 5 and adapted for guiding condensed water drops from the water valve device 7 to the drip tray 2 (with respect to condensed water flowing direction, please refer to FIG. 6 ).
  • the drip tray 2 comprises a backwardly extended water-guide hole 21 , and a side hole 22 (see FIG. 7 ) connected to a water collection box 9 by a connection tube 23 (see FIG. 8 ).
  • the water collection box 9 is arranged at the bottom side of the electrical control panel 5 inside the body of the air conditioner (see FIGS. 3 , 4 and 5 ). Further, the water collection box 9 has a water pump 91 and a water level sensor 92 arranged therein (see FIG. 3 ) and electrically coupled to the circuit board unit 6 , constituting a second water discharge path.
  • the fan motor 4 is a DC motor controlled by the circuit board unit 6 , enabling the air conditioner can achieve thermostat control and save energy consumption. Of course, the fan motor 4 can be an AC motor without thermostat control and energy saving functions.
  • the water valve device 7 can be accommodated inside the machine body of the air conditioner and disposed in the electrical control panel 5 without occupying any evaporator space.
  • the length of the evaporator 1 can be maximized to provide enhanced cooling capacity.
  • the water guide set 8 guides condensed water drops from the water valve device 7 to the drip tray 2 , avoiding water leakage and meeting the requirements for wall mount application.
  • collected water can be selectively discharged through the backwardly extended water-guide hole 21 of the drip tray 2 (the first water discharge path) or through the side hole 22 and the water collection box 9 (the second water discharge path) subject to the conditions of the installation place or the consumer's preference.
  • the invention has the water valve device 7 mounted in the electrical control panel 5 inside the machine body of the air conditioner without lowering the cooling capacity of the evaporator 1 .
  • the invention greatly improves the effects of the wall-mounted chilled water air conditioner.
