[Detailed Description of the Invention] This #3A is a forced circulation a! between the radiator of the greenhouse and the hot water storage tank! The hot water is heated by the heat released from the refrigerant condenser in the engine-driven heat pump and the engine exhaust heat, and the hot water temperature detected by a sensor installed in the hot water tank is maintained at a set temperature. The present invention relates to greenhouse heating equipment configured to control the operation of an engine so as to control the operation of the engine.

When heating a greenhouse, the capacity of the engine heat pump installed should be adjusted to handle the maximum load, but it is not possible to introduce a large load that occurs once a year or once a year, with an extremely low incidence. This invention is not an idiot that will increase the cost of installing equipment, but will also reduce engine operating efficiency under normal loads and increase running costs. By adding a boiler that can be introduced at a low cost and has low maintenance costs, the heat pump can be operated efficiently under normal load conditions, and this auxiliary boiler can be rationally controlled to provide stable greenhouse heating. The purpose is to make #lc'j possible.

The characteristic configuration of Misfire J is that in the greenhouse heating equipment of the above configuration, an auxiliary boiler is connected to the hot water storage tank, and the hot water storage temperature detected by the sensor is lowered below the allowable lower limit temperature set lower than the set temperature. A control circuit is attached to control the ignition of the auxiliary boiler in item 111 when the above-mentioned state has passed over the set time period, and to control the auxiliary boiler to stop when the detected hot water storage temperature becomes higher than the lower limit temperature of the above-mentioned t. At the point.

According to the above characteristic configuration, the capacity of the engine heat pump to be introduced is relatively small enough to correspond to the maximum load during normal operation, so even if an auxiliary boiler is added, the overall equipment installation cost Vi will not increase significantly. In fact, the running cost of the engine heat pump during normal load operation can be kept low, making it highly economical.

In particular, when controlling the added auxiliary boiler, it is necessary to wait until the hot water temperature in the hot water storage tank, which stores a large amount of wet water, has fallen below the lower limit of the allowable temperature range for a certain period of time before starting the auxiliary boiler. Since the auxiliary heating was stopped immediately if the temperature returned to above the allowable lower limit after testing the J1 product, boiler control became stable.

The hot water storage tank accumulates heat from many rats and balances against changes in heat load, so even if the hot water temperature falls below the upper and lower limits of FF due to a short-term increase in load, the heating capacity will remain unchanged. The water temperature will not drop to an extreme level, and the heat pump's ability will restore the stored hot water temperature in a relatively short amount of time. Therefore, even if the auxiliary boiler is immediately ignited when the temperature drops below the minimum capacity limit under a large load for a short period of time, the fire must be extinguished during the extreme smoke period, and unnecessary VCMJ auxiliary boilers may be activated. This speeds up the replenishment of fuel and causes early wear and tear on the combustion section.

In contrast, in the present invention, the auxiliary boiler is ignited only when the stored hot water temperature drops as a result of a long-lasting crystal load. The iQi auxiliary boiler does not require the use of all boilers, and the auxiliary boiler can be effectively used to maintain a stable hot water storage temperature.
