Definitions

• Known hot water surface heating systems contain heating water circulation pumps, antifreeze, breather and expansion vessels. You can get muddy.
• Known heat pumps for space heating / cooling often contain a condenser that transfers the heat of condensation to an additional heating medium.
• the object of the invention is to dispense with all the parts or media listed and, in addition, to significantly improve the effectiveness of heating or cooling. Other tasks are: a) to reduce the manufacturing, operating and maintenance costs, bj to install a heating system with little additional effort for cooling put,
• the metal heating pipe is laid naked in the arrangement determined above, whereby it should be set to 25 before or immediately after laying, for example with oil-free compressed air inflated bar and thus biased. Then the exact heating pipe is carefully installed in commercially available concrete, screed or plaster with the least possible addition of water. Due to the internal pressure, tight bending radii can be achieved by a single person when laying by hand and the feared kinking of the pipe hardly occurs. The pressure in the heating pipe is continuously monitored, for example by a manometer. Damages can be discovered immediately. Corrosion damage to the outside of a fully embedded SF-CU F 20 copper pipe is rare. Practically all corrosion damage that has occurred so far can be traced back to one of the following cases, see, inter alia, (11):
• the concrete aggregate contains carbon, e.g. ash, b) it contains faeces, ammonia, urea, chlorides etc., c) the embedding is not tight against substances aggressive to copper, e.g. FeCl 3 and other water treatment agents.
• the heating pipe is used as a condenser of a refrigeration system, as described below.
• the refrigeration system is evacuated, dried and with a refrigerant: e.g. filled with R 12 (4) or, more environmentally friendly, with R 22 (4) or - after completion of the extensive test program (5) - with H-car 134a.
• Another advantage of the heat pump direct underfloor heating according to the invention is that the refrigerant gas overheats - 20 to 30% of the heat of condensation is released due to the system at a higher temperature level than it corresponds to the condensation temperature - into the edge zone, see DIN 4725 Part 1 Point 2.6 , is led, which then heats up particularly strongly - even at a low condensation temperature. This is not associated with any deterioration in efficiency.
• the evaporation temperature is usually higher to use the cooling capacity of this system particularly high, it is essentially only necessary, e.g. B. by a commercially available, inexpensive, automatically operated reversing valve to reverse the refrigerant flow so that the condenser surface in the ceiling is now evaporator.
• a water storage (12) with a capacity of several cubic meters as the source of the heat, if it is available, and even to freeze it, if necessary, in order to utilize the heat of solidification (ice dispenser). If this water dispenser (12) is also to be used, for example, for garden irrigation, the evaporator (13) would have to be installed at the lowest point of the store in order to be able to draw off a lot of water without significantly impeding the function of the heat pump. This is disadvantageous because a cold zone is formed at the bottom when the memory (12) is full.
• An advantage of the heat pump direct underfloor storage heating is that it can be reliably protected against impermissible temperatures by a simple pressostat connected on the high pressure side, which switches off the compressor when the set pressure, which corresponds exactly to the condensation temperature, is exceeded.
• underfloor heating according to the invention can in no way be carried out with the plastic pipes introduced in underfloor heating construction, because these are by no means completely diffusion-tight compared to the refrigerants used, cf. (6).
• the floor heating according to the invention does not count to that in Reeknagel, Sprenger, H ⁇ nmann see above. for the prior art described in 1988/1989.
• the heating tube (4) was flux-free with phosphate-containing copper base hard solder L-CuP6 according to DIN 8513 Part 1, see (1), at point (5) with the condensate tube (6) made of SF-Cu F 20 and the pressure gauge, which was soldered in at the other end (7) brazed and inflated to 25 bar with oil-free compressed air. This pressure remained for 40 days long - apart from a damage mentioned below and temperature-related fluctuations - standing still.
• this part of the 8 cm thick load distribution layer (8) was carefully compacted. Another part was carried out with gypsum to which 30% by weight of aluminum shavings had been added.
• the evaporator (13) On the inlet side, the evaporator (13) is connected via the injection pipe (14 ') to the thermostatically controlled injection valve (15), to which the refrigerant is liquid (condensed) from the heating pipe (6) via the sight glass (16) and the refrigerant filter dryer (17) ) is supplied.
• the heating tube was damaged after laying the tiles due to ineptitude of employees.
• the damage was remedied by a brazed socket installed at the damage point. It took less than an hour of work.
• the system was initially equipped with a 26 cnr displacement compressor, which approximately 130% of the above. Design heat requirements bring, equipped, carefully evacuated and with
• a floor temperature of approx. 40 ° C and a pressure fluctuation in the heating pipe of approx. 6 bar were measured, i.e. the same value that is also measured in normal operation in the heating pipe after the compressor has been running for a long time or has been idle for a long time.
• the air temperature in the middle of the apartment on a table could be increased to 20 ° C + 1 between 7 a.m. and 10 p.m. K can be kept constant.
• the electricity consumption during a heating period was measured at 560 kWh using a counter for the electrical start of work.
• the heating energy tax should have been 2,000 kWh.
• the condensation pressure would no longer be just under 11 bar, but 15 bar, see (4).
• the pressure ratio condenser pressure to evaporation pressure would increase from 3.0 to 4.2, the delivery rate, see (6), would decrease considerably and the heat pump's work factor would decrease from approx. 3.6 to approx. 2.6;
• the power consumption of the heat pump should increase by about 40% with the same heat output due to the only 2 mm thick plastic jacket!
