Develop your own IP at cost, then you too can protect it. :D
As Tesla stated, do a search on RE, there will be a lot of information (the free sort) to help you on your way.
As I also stated, do take care of the 'condenser pinch'. Pushing temp over 80'C is possible & some of us have developed technology to do exactly this, and higher actually. We will however, protect that knowhow, in order for our families to eat.

I have said if I need IP,I will pay for it ,of course not you. NOT always exagerate such simple questions, pls kindly confirm what is IP, what isn't IP, not to say everything is IP,or you cann't speak here.
My word is not only to you, to all the persons who always want to exagerate something or with discrimination.
Here should be a place to discuss things about heat pump freely and friendly, not alway to talk so much nonsense things,or what's the meaning of establishing this forum?
Thanks for all the comments on this issue!!
Hi billliu2010,
If you & your company is serious about purchasing IP, which you now seem to be, then MF has made you an offer to assist. Talk with him, using the private-mail feature on the RE board. He's a nice guy & will get you sorted out, I'm sure.
All the best & apologies for being a little hard on you. :)
in a design phase if something is regarded as a design secret or IP.. why even post about it on an open forum?
I work on and design a lot of things.. some of the projects are fun, some are proof of concept, some are truly design.. I only post on an open internet forum those projects and ideas which i feel may be helpful to others without compromising my possible future business ventures....
sure, like anyone else I enjoy and like to entertain others' ideas, however I dont Expect just because I post here that someone is going to come along and do the job for me for free.... so I expect on a forum vague ideas and responses... often those point me in a direction that is a huge help..

different jobs ,different requirement, different opinions! I'm sales ,only concept, no IP needed, so pls don't worry, I won't seize your bowl. :off topic:
The story-line morphs yet again. :D
I thought I would clear up the IP
The vapour compression refrigeration cycle has been around over 100 years, it has been tweeked, different compressor, elctronics, refrigerants, but all said and done it has not changed, you can not beat the laws of physics.
So you need six parts, compressor, evap, cond, expansion device, refrigerant and some thing to drive the system. Understand this then you are on your way.
IP or could be said Knowledge, this is gained through experience, some information we share, other information we do not. The NOT information is normally info that may effect our businesses, thus our families. Of course this information can always be purchased, this is the case when ever you pay for something that you can not do yourself.
In this field it is normally the concept/application that is classed as IP more than specifics, very few of use can say that we have built a whole system from raw materials (I have not), most still requirer major components from others, example compressor (only a limited number of manufactures world wide)
IP, or specialised knowhow.
Every professional uses their specialised knowhow to earn a living - lawyers, doctors etc. Engineers are no different.
Raising water temp reliably & safely to 80'C does require a certain amount of specialised knowhow - this knowhow comes at a cost in terms of design, experimentation & analysis expenses. The specialist engineer has a right to both protect this knowhow, & to charge for it, in order to recover their financial outlay.
What many specialists do, however, is to combined their specific expertise into co-operative ventures, where information is inter-traded, until a certain final product is ready for market release. The profits from these products are then shared amongst the co-operative partners.
Much of the information on RE is of a very general nature & can be freely shared. The ethical questions arise when specialist information is requested. If certain members are prepared to provide this information at no cost, then that is their right. We all have different views on where we draw the line.
Every IP have protection peroid,this is,maybe today it's is IP,tomorrow is know-how/knowledge, so during the protection peroid, illegal usage is forbidden ........
Cascade second stage is the only reliable way to reach these temperatures. R410A over R134A seems to be the answer.Quote:

I am able to store 50% more energy in a cylinder (if required, but normally not) than present systems available in NZ, the system is able to work in bigger ambient ranges, and has greater COPs than any system presently on the market. All this makes the unit much more reliable, than any system on the market.Quote:

In each case with a general reducion in power of 30% for the same amount of stored energy produced. They are mechanical principles, not electrical savings (which would further improve COP, ie DC motors)
