Initial Concepts

The Concepts where broken down into three different types.

-Heating

-Cooling

-Configuration

Problems with Condensation

configuration
Configuration

One of the most important ways to save space.

Folding areas give a reduction of space with

good maintenance. Unfortunately they do not

Have a long life span.

A vertical design saves space but

Is hard to maintain.

horizontal designs
Horizontal Designs

Horizontal Designs are easy to construct and work on. They are also the largest and most unwieldy of the designs.

slide11
In order to select a concept, we needed to be able to visualize the system

The dimensions of the house will not be defined until after the competition

Initially, we used 2-D methods to find the most compact design

slide12
Three dimensional models are generally easier to work with

Components sketched in CAD were to complex to arrange

The current system can be modeled in terms of “chunks”

CompressorBlack & White

Pumps Blue, Green

Heat Exchangers Red, Orange

Check Valves Cream

Expansion Valves Silver

Liquid Line Dryers Black

Solenoid Valves Gold

Sight Glass White

Four-way Valve Brown

We modeled the system using color-coded blocks

slide13
The current hot water tank and fan coil unit may restrict the heat pump space

slide14
Our objective for the first design was to meet the geometric specifications

To Fan Coil Unit

20”

One drawback to the design is the internal piping

20”

24”

Based on customer needs, ease of maintenance was rated a 1.4

In the future, we could modify the design with external piping

To Tempered Water Tank

To Hot Water Tank

slide15
A number of geometrical configurations for the system are possible

This system, mounted vertically, conserves floor space

14”

36”

Other advantages include the external piping and separate switches

In the future, more design options will be offered
