Ergonomic heating and cooling equipment

Abstract

A chiller system for supplying chilled water to a building is provided. Embodiments of the presented disclosure relate to chiller systems using a plurality of ergonomic control boxes. In some embodiments, the ergonomic control boxes are in wireless data communication with each other and/or with one or more sensors located outside of the control boxes. Embodiments of the present disclosure allow an operator to access the control panels without the use of a ladder or stairs. Embodiments of the present disclosure relate to a chiller system that does not require an operator to reach overhead in order to adjust the operations of the chiller system.

1 . A chiller system comprising:
 a chiller wherein the chiller has a capacity of at least 30 tons;   a first chiller control box wherein the first chiller control box resides entirely within the footprint of the chiller and has an upper surface that is less than two meters above the surface the chiller rests on; and   a second chiller control box, wherein the second chiller control box resides entirely within the footprint of the chiller and has an upper surface that is less than two meters above the surface the chiller rests on, and the second chiller control box is in data communication with the first chiller control box.   
     
     
         2 . The chiller system of  claim 1 , wherein the second chiller control box is in wireless data communication with the first chiller control box. 
     
     
         3 . The chiller system of  claim 1 , wherein the second chiller control box is in 5G data communication with the first chiller control box. 
     
     
         4 . The chiller system of  claim 1 , wherein at least one chiller control box provides an indication of the communication status between the chiller control boxes. 
     
     
         5 . The chiller system of  claim 1 , wherein the chiller system comprises a refrigerant at least partially comprising a refrigerant selected from the group consisting of R410A, R32, R454B, R452B, HFO-1234ze, HFO-1233zd, R134a, R513A, R515A, R515B, and HFO-1234yf. 
     
     
         6 . The chiller system of  claim 1 , further comprising a third chiller control box in data communication with at least one of the first and second chiller control boxes. 
     
     
         7 . The chiller system of  claim 1 , further comprising one or more temperature sensors, one or more pressure sensors, and one or more voltage sensors, and wherein the first and second control boxes each contain one of more programmable logic controllers and a local wireless communication module. 
     
     
         8 . A refrigeration system comprising:
 a chiller with at least a 300 refrigeration ton (RT) capacity mounted on a frame;   one of more programmable logic controllers;   a first control box mounted on the frame; and   a second control box mounted on the frame, wherein the first control box is in wireless communication with the second control box, and wherein the first and second control boxes each have an upper side and a lower side, wherein the lower side of the first control box and second control box is 1.6 meters high and the upper side of the first control box and second control box is 1.8 meters high.   
     
     
         9 . A refrigeration system comprising:
 a chiller with at least a 300 refrigeration ton (RT) capacity;   one or more temperature sensors;   one or more pressure sensors;   one or more voltage sensors;   one of more programmable logic controllers; and   three or more control boxes, wherein the majority of the control boxes are positioned such that the bottom of the control boxes are less than 1.6 meters high, wherein the majority of the control boxes are less than 0.5 meters tall, and wherein one or more of the control boxes comprises a local wireless communication module configured to wirelessly receive data from at least one of the temperature sensors, pressure sensors, or voltage sensors.
