Chiller unit

Abstract

In a chiller unit having a chiller unit main body that is disposed to be juxtaposed with an outdoor unit and performs heat-exchange between refrigerant supplied from the outdoor unit and water medium supplied from the outside to generate cold or hot water, a refrigerant pipe and a water medium pipe connected to the plate type heat exchanger are led out to the back surface side of the chiller unit main body, a refrigerant pipe of the chiller unit main body and a refrigerant pipe of the outdoor unit are connectable to each other at the back surface side concerned, an electrical component box wounded by a heat insulating member is disposed at the front surface side of the chiller unit main body and an electrically-operated valve for controlling a flow rate of refrigerant is disposed below the electrical component box.

1 . A chiller unit having a chiller unit main body comprising:
 a plate type heat exchanger unit for performing heat exchange between refrigerant supplied from an outdoor unit through a refrigerant pipe and water medium supplied from the outside through a water refrigerant pipe to generate cold or hot water;   an electrical component box that includes electronic equipment and is disposed at the front surface side of the chiller unit main body and surrounded by a heat insulating member; and   an electrically-operated valve that is disposed below the electrical component box and controls a flow rate of refrigerant flowing through the refrigerant pipe of the chiller unit main body, wherein the refrigerant pipe and the water medium pipe connected to the plate type heat exchanger unit are lead out to the back surface side of the chiller unit main body, and a refrigerant pipe of the chiller unit main body is connectable to the refrigerant pipe from the outdoor unit at the back surface side.   
   
   
       2 . The chiller unit according to  claim 1 , wherein the outdoor unit and the chiller unit main body are arranged side by side and the width in the depth direction of the chiller unit main body and the width in the width direction of the outdoor unit are set to be substantially equal to each other. 
   
   
       3 . The chiller unit according to  claim 1 , wherein the chiller unit main body and the outdoor unit are mounted on a vibration-proof table. 
   
   
       4 . A chiller unit having a chiller unit main body comprising:
 a housing having an upper stage portion and a lower stage portion;   a plate type heat exchanger unit for performing heat exchange between refrigerant supplied from an outdoor unit through a refrigerant pipe and water medium supplied from the outside through a water medium pipe to generate cold or hot water; and   a pipe group connected to the refrigerant pipe from the outdoor unit and the water medium pipe from the outside to supply the refrigerant and the water medium to the plate type heat exchanger unit, wherein the pipe group supplies the refrigerant and the water medium to the plate type heat exchanger unit while splitting the flow of each of the refrigerant and the water medium, the pipe group is collectively disposed in the lower stage portion of the chiller unit main body, and the pipe group is connected to the plate type heat exchanger unit so that the pipe group is located to be equal to or lower than the top portion of the plate type heat exchanger unit in height.   
   
   
       5 . The chiller unit according to  claim 4 , wherein the chiller unit main body has a support table substantially at the center portion in the height direction thereof, and the plate type heat exchanger unit is mounted on the support table and also secured to a side portion of the chiller unit main body through a support plate. 
   
   
       6 . The chiller unit according to  claim 4 , wherein the plate type heat exchanger unit comprises a plurality of plate type heat exchangers that are arranged so as to be spaced from one another and secured to counter-side portions of the chiller unit main body so that the weight balance of the whole chiller unit is kept. 
   
   
       7 . The chiller unit according to  claim 4 , wherein a through hole through which the water medium pipe is led out from the chiller unit main body is provided at the lower portion of the back surface of the chiller unit main body. 
   
   
       8 . A chiller unit having a chiller unit main body that is disposed to be juxtaposed with an outdoor unit and performs heat-exchange between refrigerant supplied from the outdoor unit and water medium supplied from the outside to generate cold or hot water, wherein a refrigerant pipe and a water medium pipe connected to the plate type heat exchanger are led out to the back surface side of the chiller unit main body, a refrigerant pipe of the chiller unit main body and a refrigerant pipe of the outdoor unit are connectable to each other at the back surface side concerned, an electrical component box wounded by a heat insulating member is disposed at the front surface side of the chiller unit main body and an electrically-operated valve for controlling a flow rate of refrigerant is disposed below the electrical component box.
