Abstract

A well (1) is bored, producing at least 51 water per sq.m. floor area. This provides house and garden raw water and hot water requirements, and supplies working fluid for a reversible heat-pump (2) delivering hot water at 45-50 degrees C and chilled water at 3-6 degrees C. The latter is applied to air conditioning, cold storage (9) and wine cellar (8) purposes; the former to domestic space and water heating, and to swimming pool heating (3). The space heating system includes room heater/air conditioners (6), with circulating fans, and/or floor and wall heating coils (7). The various applications rely extensively on automatic controls to maintain set conditions with optimum energy conservation. Optionally, these systems include remote operation and alarms.

Description

 The present invention is intended to supply all or part of the hot and cold energy, of a detached house or any local, from a single generator.

 This thermodynamic electric generator alone ensures the following needs, SUMMER and WINTER: - heating of all rooms.

- the cooling of all the rooms.

- production of domestic hot water at 450C.

- cold water necessary for watering and water needs other than food.

- heating of an outdoor swimming pool.

- maintaining the temperature and humidity of a wine cellar incorporated or not in the construction at a TOC of 130C and 50% RH.

- maintaining at a temperature of 6/8 "C a cold room thermally insulated with 7 cm of polystyrene on all the walls.

 All the aforementioned needs are traditionally satisfied by several individual generators at higher operating costs, whatever the energies or networks used, such - hot generator for heating.

- cold generator for cooling.

- generators sometimes reversible hot / cold but ensuring only these 2 functions.

- water heater.

- pool heater.

- cellar air conditioner.

- public water supply - refrigerator.

 The invention includes: - 1 sensor - 1 generator - several transmitters.

It allows from these three components to supply, distribute and use raw water, hot water and iced water for the different needs of a single house or premises with identical needs.

 The attached documents represent - Figure 1: the block diagram of the invention.

- Figure 2: the drawing of a perspective realization with all the equipment installed.

SUMMER WINTER.

 Sensor (Reference 1): It is a borehole recovering calf from an aquifer at a constant temperature varying according to the regions from 12 to 14 "C. The water requirements are 5 liters / m2 of surface to be heated or cool. It can also be sensors buried in the ground in which circulates a heat transfer fluid (glycol water) at low temperature (from +10 to -10 C). These sensors recover energy from the ground between 0, 5 and 3 ml deep.

 Generator (Item 2): It is a group of chilled water water / water with any refrigerant simultaneously supplying - hot water at 45/50 "C.

- 3/6 "C glazed veal.

 The differences in T "C being obtained by manual or automatic modifications of the flow rates at the inlet of the condenser and of the evaporator of the generator reference 2.

 The water supplied by the two generator organs (evaporator or condenser) is used or not depending on the needs and the season. Thus the heating of the swimming pool will be provided free of charge, when it is necessary to cool the premises. Hot water can be supplied at 45 "C all year round, whatever the hot or cold needs of the premises from the reference tank 3.

The generator power is as follows
For 1 kWh consumed; it produces - 3.5 kWh hot - 2.5 kWh cold or 6 kWh provides for 1 kWh consumed.

The installed power is 25W / m2 (+ or - 20% depending on the sites and the degree of thermal insulation) for the generator.

 The regulation of the generator is carried out according to the needs and the season on the return of hot water or chilled water. Thus in SUMMER, the regulation has priority over the cold, the valves reference 4 are open and the valves item 5 are closed. In WINTER, regulation takes priority over heating, the valves reference 4 are closed, the valves reference 5 are open.

The distribution of raw water can be a generator running.

 Transmitters (marks 6, 7, 8 and 9): They are of 4 types: - Mark 6: Fan coil units with simple hot / cold batteries individually regulated by thermostat or room sensor with or without regulators, for living rooms of the house or room.

- Reference 7: Heating / cooling floor in crosslinked polyethylene embedded in the slab representing a power of - 25 W / ml in hot for water at 30 "C - 10 W / ml in cold for water at 15" vs.

The floor is regulated by a 4-way valve controlled by the external TOC.

- Reference 8: Fan coil double hot / cold coil with humidifier regulated by double 3-way valve, T "C probe and HR probe.

- Reference 9: Exchanger by serpentine dito floor in crosslinked polyethylene or copper hardened on the ground and vertical walls, at the rate of 1 ml of tube for 30 W of cold power to be supplied for a T "C of distribution of + 4 / + 60C, with the possibility of lowering to + 3 / + 5 "C.

The cold room is fitted with a floor siphon for condensate drainage.

 The invention can be applied in new and existing premises. The low water requirements mean that it can be applied almost everywhere. It can operate on surface water, watercourses, lakes, ponds and also on sea water with an intermediate exchanger. All companies specialized in heating and air conditioning can set it up. We can associate it with all possible home automation systems such as watering remote control.

- automatic remote start.

- optimization of consumption.

- remote alarm.

- etc ...
