Title:
METHOD AND DEVICE FOR DRIVING COOLING AND HEATING LOAD
Document Type and Number:
Japanese Patent JPH01196468
Kind Code:
A
Abstract:
PURPOSE:To permit cooling, freezing or refrigerating in some place and permit heating or hot-water supplying in the other place based on demand, by a method wherein heat pumps, operated by employing medium hot-water, generated by a medium hot-water generator, are arranged in respective places. CONSTITUTION:Medium hot-water, having a temperature in the degree of 15-20 deg.C throughout a year, is generated by a medium hot-water generator 1 and is supplied to air-conditioning electric heat pumps 4, arranged in a plurality of places, through a pump 2 and a pipeline 3, thereafter, is returned to the medium hot-water generator 1 after effecting cooling or heating to circulate it. When a space, wherein the heat pump 4A is arranged, for example, requires cooling, cooling operation is effected by the heat pump 4A employing the medium hot-water as cooling water. When another space, wherein the heat pump 4B is arranged, requires heating, heating operation is effected by the heat pump 4B employing the medium hot-water as heat source water. Accordingly, cooling or heating operation may be effected in accordance with the request of respective air-conditioning spaces. According to this method, energy for cooling, heating, hot-water supplying, refrigerating, freezing or the like is subtracted whereby the thermal load of the medium hot-water generator may be reduced.
